Accounting Policies [Abstract] | |
Basis of Presentation and Significant Accounting Policies | Basis of Presentation and Significant Accounting Policies Basis of Presentation: The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP, for interim financial reporting. Accordingly, they do not include all of the information and footnotes required by GAAP for annual financial statements. We have omitted certain footnote disclosures that would substantially duplicate the disclosures in our 2017 Annual Report on Form 10-K, unless the information contained in those disclosures materially changed or is required by GAAP. Certain prior year amounts have been reclassified to conform to the current year presentation or adjusted to conform to the current year rounding convention. In the opinion of management, all adjustments, including normal recurring adjustments, necessary for a fair statement of the consolidated financial statements as of and for the three and nine months ended September 30, 2018 and 2017 have been recorded. The results of operations for the three and nine months ended September 30, 2018 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2018 , or any other period. These unaudited consolidated financial statements should be read in conjunction with our audited consolidated financial statements as of and for the year ended December 31, 2017 included in our 2017 Annual Report on Form 10-K. Cash and Cash Equivalents: Certain of our subsidiaries operate outside of the United States and have functional currencies other than the U.S. dollar, or USD. We translate the assets and liabilities of those subsidiaries to USD using the exchange rate in effect at the end of the period. We translate the revenues and expenses of those subsidiaries to USD using the average exchange rates in effect during the period. The net effect of these translation adjustments is included in “Foreign currency translation adjustments” in our consolidated statements of comprehensive income. Additionally, we control a number of bank accounts that are used exclusively to hold customer funds for the administration of customer benefits and have cash and cash equivalents on deposit to meet certain regulatory requirements. These amounts totaled $243 and $182 at September 30, 2018 and December 31, 2017 , respectively and are included in the cash and cash equivalents line on our consolidated balance sheets. Revenue Recognition: Premiums for fully-insured contracts are recognized as revenue over the period insurance coverage is provided, and, if applicable, net of amounts recognized for the minimum medical loss ratio rebates or contractual or government-mandated premium stabilization programs. Administrative fees and other revenue includes revenue from certain group contracts that provide for the group to be at risk for all, or with supplemental insurance arrangements, a portion of their claims experience. We charge these self-funded groups an administrative fee, which is based on the number of members in a group or the group’s claim experience. Under our self-funded arrangements, revenue is recognized as administrative services are performed, and benefit payments under these programs are excluded from benefit expense. For additional information about our revenues, see Note 2, “Basis of Presentation and Significant Accounting Policies” and Note 19, “Segment Information,” to our audited consolidated financial statements as of and for the year ended December 31, 2017 included in our 2017 Annual Report on Form 10-K. In addition, see Note 15, “Segment Information,” herein for the disaggregation of revenues by segments and products. Premium and self-funded receivables include the uncollected amounts from insured groups, individuals and government programs. Premium receivables are reported net of an allowance for doubtful accounts of $312 and $302 at September 30, 2018 and December 31, 2017 , respectively. Self-funded receivables are reported net of an allowance for doubtful accounts of $40 and $153 at September 30, 2018 and December 31, 2017 , respectively. For our non-fully-insured contracts, we had no material contract assets, contract liabilities or deferred contract costs recorded on our consolidated balance sheet at September 30, 2018 . For the three and nine months ended September 30, 2018 , revenue recognized from performance obligations related to prior periods, such as due to changes in transaction price, was not material. For contracts that have an original expected duration of greater than one year, revenue expected to be recognized in future periods related to unfulfilled contractual performance obligations and contracts with variable consideration related to undelivered performance obligations is not material. Recently Adopted Accounting Guidance: In February 2018, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update No. 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income , or ASU 2018-02. On December 22, 2017, the federal government enacted a tax bill, H.R.1, An act to provide for reconciliation pursuant to titles II and V of the concurrent resolution on the budget for fiscal year 2018 , or the Tax Cuts and Jobs Act. The Tax Cuts and Jobs Act contains significant changes to corporate taxation, including, but not limited to, reducing the U.S. federal corporate income tax rate from 35% to 21% and modifying or limiting many business deductions. Current FASB guidance requires adjustments of deferred taxes due to a change in the federal corporate income tax rate to be included in income from operations. As a result, the tax effects of items within accumulated other comprehensive loss did not reflect the appropriate tax rate. The amendments in ASU 2018-02 allow a reclassification from accumulated other comprehensive loss to retained earnings for stranded tax effects resulting from the change in the federal corporate income tax rate. We adopted the amendments in ASU 2018-02 for our interim and annual reporting periods beginning on January 1, 2018 and reclassified $91 of stranded tax effects from accumulated other comprehensive loss to retained earnings on our consolidated balance sheet. The adoption of ASU 2018-02 did not have any impact on our results of operations or cash flows. In May 2017, the FASB issued Accounting Standards Update No. 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting , or ASU 2017-09. This update provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. We adopted ASU 2017-09 on January 1, 2018. The guidance has been and will be applied prospectively to awards modified on or after the adoption date. The adoption of ASU 2017-09 did not have any impact on our consolidated financial position, results of operations or cash flows. In March 2017, the FASB issued Accounting Standards Update No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost , or ASU 2017-07. This amendment requires entities to disaggregate the service cost component from the other components of the benefit cost and present the service cost component in the same income statement line item as other employee compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. Certain of our defined benefit plans have previously been frozen, resulting in no annual service costs, and the remaining service costs for our non-frozen plan are not material. We adopted ASU 2017-07 on January 1, 2018 and it did not have a material impact on our results of operations, cash flows or consolidated financial position. In December 2016, the FASB issued Accounting Standards Update No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers , or ASU 2016-20 . In May 2016, the FASB issued Accounting Standards Update No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients , or ASU 2016-12. In April 2016, the FASB issued Accounting Standards Update No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing , or ASU 2016-10. In March 2016, the FASB issued Accounting Standards Update No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross verses Net) , or ASU 2016-08. These updates provide additional clarification and implementation guidance on the previously issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) , or ASU 2014-09. Collectively, these updates require a company to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. These updates supersede almost all existing revenue recognition guidance under GAAP, with certain exceptions, including an exception for our premium revenues, which are recorded on the Premiums line item on our consolidated statements of income and will continue to be accounted for in accordance with the provisions of Accounting Standards Codification, or ASC, Topic 944, Financial Services - Insurance . Our administrative service and other contracts that are subject to these Accounting Standards Updates are recorded in the Administrative fees and other revenue line item on our consolidated statements of income and represents approximately 6% of our consolidated total operating revenue. We adopted these standards on January 1, 2018 using the modified retrospective approach. The adoption of these standards did not have a material impact on our beginning retained earnings, results of operations, cash flows or consolidated financial position. In November 2016, the FASB issued Accounting Standards Update No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, or ASU 2016-18. This update amends ASC Topic 230 to add and clarify guidance on the classification and presentation of restricted cash in the statement of cash flows. The guidance requires entities to show the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. We adopted ASU 2016-18 on January 1, 2018 using a retrospective approach. The adoption of ASU 2016-18 did not have a material impact on our consolidated statements of cash flows and did not impact our results of operations or consolidated financial position. In August 2016, the FASB issued Accounting Standards Update No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, or ASU 2016-15. This update addresses the presentation and classification on the statement of cash flows for eight specific items, with the objective of reducing existing diversity in practice in how certain cash receipts and cash payments are presented and classified. We adopted ASU 2016-15 on January 1, 2018. The adoption of ASU 2016-15 did not have a material impact on our consolidated statements of cash flows, results of operations or consolidated financial position. In January 2016, the FASB issued Accounting Standards Update No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities , or ASU 2016-01. The amendments in ASU 2016-01 change the accounting for non-consolidated equity investments that are not accounted for under the equity method of accounting by requiring changes in fair value to be recognized in income. Additionally, ASU 2016-01 simplifies the impairment assessment of equity investments without readily determinable fair values; requires entities to use the exit price when estimating the fair value of financial instruments; and modifies various presentation disclosure requirements for financial instruments. We adopted ASU 2016-01 on January 1, 2018 as a cumulative-effect adjustment and reclassified $320 of unrealized gains on equity investments, net of tax, from accumulated other comprehensive loss to retained earnings on our consolidated balance sheet. Effective January 1, 2018, our results of operations include the changes in fair value of these financial instruments. Recent Accounting Guidance Not Yet Adopted: In August 2018, the FASB issued Accounting Standards Update No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract , or ASU 2018-15. The amendments in ASU 2018-15 require implementation costs incurred by customers in cloud computing arrangements to be deferred and recognized over the term of the arrangement, if those costs would be capitalized by the customer in a software licensing arrangement under the internal-use software guidance. The amendments also require an entity to disclose the nature of its hosting arrangements and adhere to certain presentation requirements in its balance sheet, income statement and statement of cash flows. ASU 2018-15 is effective for our interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. The guidance can be applied either prospectively to all implementation costs incurred after the date of adoption or retrospectively. We are currently evaluating the effects the adoption of ASU 2018-15 will have on our consolidated financial position, results of operations and cash flows. In August 2018, the FASB issued Accounting Standards Update No. 2018-14, Compensation—Retirement Benefits - Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans , or ASU 2018-14. The amendments in ASU 2018-14 eliminate, add, and modify certain disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The amendments are effective for our annual reporting periods beginning after December 15, 2020, with early adoption permitted. The guidance is to be applied on a retrospective basis to all periods presented. We are currently evaluating the effects the adoption of ASU 2018-14 will have on our disclosures. In August 2018, the FASB issued Accounting Standards Update No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, or ASU 2018-13. The amendments in ASU 2018-13 eliminate, add, and modify certain disclosure requirements for fair value measurements. The amendments are effective for our interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted for either the entire ASU or only the provisions that eliminate or modify requirements. The amendments with respect to changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty are to be applied prospectively. All other amendments are to be applied retrospectively to all periods presented. We are currently evaluating the effects the adoption of ASU 2018-13 will have on our disclosures. In August 2018, the FASB issued Accounting Standards Update No. 2018-12, Financial Services—Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts, or ASU 2018-12. The amendments in ASU 2018-12 make changes to a variety of areas to simplify or improve the existing recognition, measurement, presentation and disclosure requirements for long-duration contracts issued by an insurance entity. The amendments require insurers to annually review the assumptions they make about their policyholders and update the liabilities for future policy benefits if the assumptions change. The amendments also simplify the amortization of deferred contract acquisition costs and add new disclosure requirements about the assumptions insurers use to measure their liabilities and how they may affect future cash flows. The amendments in ASU 2018-12 will be effective for our interim and annual reporting periods beginning after December 15, 2020. The amendments related to the liability for future policy benefits for traditional and limited-payment contracts and deferred acquisition costs are to be applied to contracts in force as of the beginning of the earliest period presented, with an option to apply such amendments retrospectively with a cumulative-effect adjustment to the opening balance of retained earnings as of the earliest period presented. The amendments for market risk benefits are to be applied retrospectively. We are currently evaluating the effects the adoption of ASU 2018-12 will have on our consolidated financial position, results of operations, cash flows, and related disclosures. In July 2018, the FASB issued Accounting Standards Update No. 2018-11, Leases (Topic 842): Targeted Improvements , or ASU 2018-11, and Accounting Standards Update No. 2018-10, Codification Improvements to Topic 842, Leases , or ASU 2018-10. The amendments in ASU 2018-11 provide for an additional and optional transition method that allows an entity to initially apply ASC Topic 842 at the adoption date and recognize a cumulative effect adjustment to its opening balance of retained earnings in the period of adoption and continue its reporting for the comparative periods presented in accordance with the current lease guidance, ASC Topic 840. The amendments in ASU 2018-11 also provide lessors with a practical expedient, by class of underlying asset, to not separate nonlease components from the associated lease component and, instead, to account for those components as a single component if the nonlease components otherwise would be accounted for under the new revenue guidance, ASC Topic 606 and if certain conditions are met. The amendments in ASU 2018-10 provide additional clarification and implementation guidance on certain aspects of the previously issued Accounting Standards Update No. 2016-02, Leases (Topic 842), or ASU 2016-02, and have the same effective and transition requirements as ASU 2016-02. Upon the effective date, ASU 2016-02 will supersede the current lease guidance in ASC Topic 840. Under the new guidance, lessees will be required to recognize for all leases, with the exception of short-term leases, a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis. Concurrently, lessees will be required to recognize a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASU 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. ASU 2016-02 requires a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative periods presented in the financial statements. As noted above, ASU 2018-11 provides for an additional and optional transition method. We plan to apply the optional transition method at the adoption date and are currently evaluating the effects the adoption of ASU 2016-02 will have on our consolidated financial statements, results of operations and cash flows. In July 2018, the FASB issued Accounting Standards Update No. 2018-09, Codification Improvements, or ASU 2018-09. This amendment makes changes to a variety of topics to clarify, correct errors in, or make minor improvements to the Accounting Standards Codification. The majority of the amendments in ASU 2018-09 will be effective for us in annual periods beginning after December 15, 2018. We are currently evaluating the effects the adoption of ASU 2018-09 will have on our consolidated financial statements, results of operations and cash flows. There were no other new accounting pronouncements that were issued or became effective since the issuance of our 2017 Annual Report on Form 10-K that had, or are expected to have, a material impact on our consolidated financial position, results of operations or cash flows. |

Business Combinations [Abstract] | |
Business Acquisitions | Business Acquisitions Acquisition of America’s 1st Choice On February 15, 2018, we completed our acquisition of Freedom Health, Inc., Optimum HealthCare, Inc., America’s 1st Choice of South Carolina, Inc. and related entities, or collectively, America’s 1st Choice, a Medicare Advantage organization that offers HMO products, including Chronic Special Needs Plans and Dual-Eligible Special Needs Plans under its Freedom Health and Optimum HealthCare brands in Florida and its America’s 1st Choice of South Carolina brand in South Carolina. At the time of acquisition, through its Medicare Advantage plans, America’s 1st Choice served approximately one hundred and thirty-five thousand members in twenty-five Florida and three South Carolina counties. This acquisition aligns with our plans for continued growth in the Medicare Advantage and Special Needs populations. In accordance with FASB accounting guidance for business combinations, the consideration transferred was allocated to the preliminary fair value of America's 1st Choice's assets acquired and liabilities assumed, including identifiable intangible assets. The excess of the consideration transferred over the preliminary fair value of net assets acquired resulted in preliminary goodwill of $1,021 at September 30, 2018 , all of which was allocated to our Government Business segment. Preliminary goodwill recognized from the acquisition of America's 1st Choice primarily relates to the future economic benefits arising from the assets acquired and is consistent with our stated intentions to strengthen our position and expand operations in the government sector to service Medicare Advantage and Special Needs populations. As of September 30, 2018 , the initial accounting for the acquisition has not been finalized. Any subsequent adjustments made to the assets acquired or liabilities assumed during the measurement period will be recorded as an adjustment to goodwill. During the nine months ended September 30, 2018 , we increased preliminary goodwill by $31 . The preliminary fair value of the net assets acquired from America's 1st Choice includes $711 of other intangible assets, which primarily consist of finite-lived customer relationships and provider networks with amortization periods ranging from 3 to 20 years. The results of operations of America's 1st Choice are included in our consolidated financial statements within our Government Business segment for the period following February 15, 2018. The pro forma effects of this acquisition for prior periods were not material to our consolidated results of operations. Acquisition of HealthSun On December 21, 2017, we completed our acquisition of HealthSun Health Plans, Inc., or HealthSun , which at the time of acquisition served approximately forty thousand members in the state of Florida through its Medicare Advantage plans, and which received a five-star rating from the Centers for Medicare & Medicaid Services. This acquisition aligns with our plans for continued growth in the Medicare Advantage and dual-eligible populations. In accordance with FASB accounting guidance for business combinations, the consideration transferred was allocated to the preliminary fair value of HealthSun's assets acquired and liabilities assumed, including identifiable intangible assets. The excess of the consideration transferred over the preliminary fair value of net assets acquired resulted in preliminary goodwill of $1,605 at September 30, 2018 , all of which was allocated to our Government Business segment. Preliminary goodwill recognized from the acquisition of HealthSun primarily relates to the future economic benefits arising from the assets acquired and is consistent with our stated intentions to strengthen our position and expand operations in the government sector to service Medicare Advantage and dual-eligible enrollees. As of September 30, 2018 , the initial accounting for the acquisition has not been finalized. Any subsequent adjustments made to the assets acquired or liabilities assumed during the measurement period will be recorded as an adjustment to goodwill. During the nine months ended September 30, 2018 , we reduced preliminary goodwill by $38 primarily due to adjustments made to acquired intangible assets, partially offset by the establishment of certain deferred tax liabilities. The preliminary fair value of the net assets acquired from HealthSun includes $637 of other intangible assets, which primarily consist of finite-lived customer relationships with amortization periods ranging from 4 to 20 years. The results of operations of HealthSun are included in our consolidated financial statements within our Government Business segment for the period following December 21, 2017. The pro forma effects of this acquisition for prior periods were not material to our consolidated results of operations. |

Investments [Abstract] | |
Investments | Investments Fixed Maturity Securities We evaluate our available-for-sale fixed maturity securities for other-than-temporary declines based on qualitative and quantitative factors. There were no individually significant other-than-temporary impairment losses on investments during the three and nine months ended September 30, 2018 and 2017 . We continue to review our investment portfolios under our impairment review policy. Given the inherent uncertainty of changes in market conditions and the significant judgments involved, there is a continuing risk that further declines in fair value may occur and additional material other-than-temporary impairment losses on investments may be recorded in future periods. A summary of current and long-term fixed maturity securities, available-for-sale, at September 30, 2018 and December 31, 2017 is as follows: Non-Credit Component of Other-Than- Other Comprehensive Loss Cost or Gross Gross Unrealized Losses Estimated Less than 12 Months 12 Months or Greater September 30, 2018 Fixed maturity securities: United States Government securities $ 634 $ 1 $ (4 ) $ (6 ) $ 625 $ — Government sponsored securities 103 — (1 ) (1 ) 101 — States, municipalities and political subdivisions, tax-exempt 4,944 66 (31 ) (15 ) 4,964 — Corporate securities 8,340 62 (98 ) (48 ) 8,256 (2 ) Residential mortgage-backed securities 2,742 26 (23 ) (52 ) 2,693 — Commercial mortgage-backed securities 68 — — (2 ) 66 — Other securities 1,174 15 (3 ) (5 ) 1,181 — Total fixed maturity securities $ 18,005 $ 170 $ (160 ) $ (129 ) $ 17,886 $ (2 ) December 31, 2017 Fixed maturity securities: United States Government securities $ 649 $ 2 $ (5 ) $ (1 ) $ 645 $ — Government sponsored securities 90 — — — 90 — States, municipalities and political subdivisions, tax-exempt 5,854 193 (5 ) (7 ) 6,035 — Corporate securities 7,363 166 (30 ) (13 ) 7,486 — Residential mortgage-backed securities 2,520 39 (8 ) (12 ) 2,539 — Commercial mortgage-backed securities 80 1 — (2 ) 79 — Other securities 1,054 14 (3 ) (1 ) 1,064 — Total fixed maturity securities $ 17,610 $ 415 $ (51 ) $ (36 ) $ 17,938 $ — For fixed maturity securities in an unrealized loss position at September 30, 2018 and December 31, 2017 , the following table summarizes the aggregate fair values and gross unrealized losses by length of time those securities have continuously been in an unrealized loss position: Less than 12 Months 12 Months or Greater (Securities are whole amounts) Number of Securities Estimated Fair Value Gross Unrealized Loss Number of Securities Estimated Fair Value Gross Unrealized Loss September 30, 2018 Fixed maturity securities: United States Government securities 45 $ 374 $ (4 ) 20 $ 206 $ (6 ) Government sponsored securities 27 66 (1 ) 17 17 (1 ) States, municipalities and political subdivisions, tax-exempt 997 1,960 (31 ) 260 383 (15 ) Corporate securities 2,243 4,642 (98 ) 593 936 (48 ) Residential mortgage-backed securities 677 1,144 (23 ) 531 1,092 (52 ) Commercial mortgage-backed securities 17 31 — 10 25 (2 ) Other securities 192 575 (3 ) 68 201 (5 ) Total fixed maturity securities 4,198 $ 8,792 $ (160 ) 1,499 $ 2,860 $ (129 ) December 31, 2017 Fixed maturity securities: United States Government securities 36 $ 450 $ (5 ) 11 $ 56 $ (1 ) Government sponsored securities 12 16 — 16 15 — States, municipalities and political subdivisions, tax-exempt 414 641 (5 ) 189 356 (7 ) Corporate securities 1,081 2,200 (30 ) 279 330 (13 ) Residential mortgage-backed securities 445 1,050 (8 ) 287 478 (12 ) Commercial mortgage-backed securities 7 14 — 12 27 (2 ) Other securities 132 406 (3 ) 20 36 (1 ) Total fixed maturity securities 2,127 $ 4,777 $ (51 ) 814 $ 1,298 $ (36 ) The amortized cost and fair value of fixed maturity securities at September 30, 2018 , by contractual maturity, are shown below.

All securities sold resulting in investment gains and losses are recorded on the trade date. Realized gains and losses are determined on the basis of the cost or amortized cost of the specific securities sold. Equity Securities A summary of current and long-term equity securities at September 30, 2018 and December 31, 2017 is as follows: September 30, 2018 December 31, 2017 Equity securities: Exchange traded funds $ 487 $ 1,300 Fixed maturity mutual funds 611 791 Common equity securities 890 1,254 Private equity securities 318 287 Total $ 2,306 $ 3,632 The gains and losses related to equity securities for the three and nine months ended September 30, 2018 are as follows: Three Months Ended September 30, 2018 Nine Months Ended September 30, 2018 Net realized gains (losses) recognized on equity securities $ 27 $ (33 ) Less: Net realized gains recognized on equity securities sold during the period (11 ) (208 ) Unrealized gains (losses) recognized on equity securities still held at September 30, 2018 $ 16 $ (241 ) The gross realized gains recognized on sales of equity securities for the three and nine months ended September 30, 2017 were $96 and $120 , respectively. The gross realized losses recognized on sales of equity securities for the three and nine months ended September 30, 2017 were $8 and $13 , respectively. Securities Lending Programs We participate in securities lending programs whereby marketable securities in our investment portfolio are transferred to independent brokers or dealers in exchange for cash and securities collateral. The fair value of the collateral received at the time of the transactions amounted to $741 and $454 at September 30, 2018 and December 31, 2017 , respectively. The value of the collateral represented 103% and 104% of the market value of the securities on loan at September 30, 2018 and December 31, 2017 , respectively. We recognize the collateral as an asset under the caption “Securities lending collateral” on our consolidated balance sheets and we recognize a corresponding liability for the obligation to return the collateral to the borrower under the caption “Securities lending payable.” The securities on loan are reported in the applicable investment category on our consolidated balance sheets. The remaining contractual maturity of our securities lending agreements at September 30, 2018 is as follows: Overnight and Continuous Securities lending transactions United States Government securities $ 131 Corporate securities 456 Equity securities 154 Total $ 741 The market value of loaned securities and that of the collateral pledged can fluctuate in non-synchronized fashions. To the extent the loaned securities' value appreciates faster or depreciates slower than the value of the collateral pledged, we are exposed to the risk of the shortfall. As a primary mitigating mechanism, the loaned securities and collateral pledged are marked to market on a daily basis and the shortfall, if any, is collected accordingly. Secondarily, the minimum collateral level is set at 102% of the value of the loaned securities, which provides a cushion before any shortfall arises. The investment of the cash collateral is subject to market risk, which is managed by limiting the investments to higher quality and shorter duration instruments. |

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
Derivative Financial Instruments | Derivative Financial Instruments We primarily invest in the following types of derivative financial instruments: interest rate swaps, futures, forward contracts, put and call options, swaptions, embedded derivatives and warrants. We also enter into master netting agreements which reduce credit risk by permitting net settlement of transactions. We had posted collateral of $14 and $12 related to our derivative financial instruments at September 30, 2018 and December 31, 2017 , respectively. A summary of the aggregate contractual or notional amounts and estimated fair values related to derivative financial instruments at September 30, 2018 and December 31, 2017 is as follows: Contractual/ Notional Amount Balance Sheet Location Estimated Fair Value Asset (Liability) September 30, 2018 Hedging instruments Interest rate swaps - fixed to floating $ 1,200 Other assets/other liabilities $ — $ (19 ) Non-hedging instruments Interest rate swaps 179 Equity securities 7 (1 ) Futures 274 Equity securities 3 (1 ) Subtotal non-hedging 453 Subtotal non-hedging 10 (2 ) Total derivatives $ 1,653 Total derivatives 10 (21 ) Amounts netted (10 ) 10 Net derivatives $ — $ (11 ) December 31, 2017 Hedging instruments Interest rate swaps - fixed to floating $ 1,235 Other assets/other liabilities $ 2 $ (5 ) Interest rate swaps - forward starting pay fixed swaps 425 Other assets/other liabilities — (9 ) Subtotal hedging 1,660 Subtotal hedging 2 (14 ) Non-hedging instruments Interest rate swaps 171 Equity securities 1 (5 ) Options 100 Other assets/other liabilities — — Futures 117 Equity securities — (2 ) Subtotal non-hedging 388 Subtotal non-hedging 1 (7 ) Total derivatives $ 2,048 Total derivatives 3 (21 ) Amounts netted (1 ) 1 Net derivatives $ 2 $ (20 ) Fair Value Hedges We have entered into various interest rate swap contracts to convert a portion of our interest rate exposure on our long-term debt from fixed rates to floating rates. The floating rates payable on all of our fair value hedges are benchmarked to LIBOR. A summary of our outstanding fair value hedges at September 30, 2018 and December 31, 2017 is as follows: Type of Fair Value Hedges Year Entered Into Outstanding Notional Amount Interest Rate Received Expiration Date September 30, 2018 December 31, 2017 Interest rate swap 2018 $ 50 $ — 4.101 % September 1, 2027 Interest rate swap 2018 450 — 3.300 January 15, 2023 Interest rate swap 2018 90 — 4.350 August 15, 2020 Interest rate swap 2017 50 50 4.350 August 15, 2020 Interest rate swap 2015 200 200 4.350 August 15, 2020 Interest rate swap 2014 150 150 4.350 August 15, 2020 Interest rate swap 2013 10 10 4.350 August 15, 2020 Interest rate swap 2012 200 200 4.350 August 15, 2020 Interest rate swap 2012 — 625 1.875 January 15, 2018 Total notional amount outstanding $ 1,200 $ 1,235 The following amounts were recorded on our consolidated balance sheets related to cumulative basis adjustments for fair value hedges at September 30, 2018 and December 31, 2017 : Balance Sheet Classification in Which Hedged Item is Included Carrying Amount of Hedged Liability Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Liability September 30, 2018 December 31, 2017 September 30, 2018 December 31, 2017 Current portion of long term-debt $ 849 $ 1,275 $ — $ 2 Long-term debt 17,300 17,382 (19 ) (5 ) Cash Flow Hedges We have entered into a series of forward starting pay fixed interest rate swaps with the objective of reducing the variability of cash flows in the interest payments on anticipated future financings. We had $425 in notional amounts outstanding under forward starting pay fixed interest rate swaps at December 31, 2017 . During the nine months ended September 30, 2018 , swaps in the notional amount of $425 were terminated. We received an aggregate of $24 from the swap counter parties upon termination. The unrecognized loss for all outstanding, expired and terminated cash flow hedges included in accumulated other comprehensive loss, net of tax, was $249 and $ 233 at September 30, 2018 and December 31, 2017 , respectively. As of September 30, 2018 , the total amount of amortization over the next twelve months for all cash flow hedges is estimated to increase interest expense by approximately $14 . No amounts were excluded from effectiveness testing. A summary of the effect of cash flow hedges in accumulated other comprehensive loss for the three and nine months ended September 30, 2018 and 2017 is as follows: Hedge Income Statement Location of Accumulated Other Comprehensive Loss Hedge Loss Type of Cash Flow Hedge Three months ended September 30, 2018 Forward starting pay fixed swaps $ — Interest expense $ (4 ) Three months ended September 30, 2017 Forward starting pay fixed swaps $ (9 ) Interest expense $ (2 ) Nine months ended September 30, 2018 Forward starting pay fixed swaps $ (33 ) Interest expense $ (10 ) Nine months ended September 30, 2017 Forward starting pay fixed swaps $ (109 ) Interest expense $ (5 ) Forward starting pay fixed swaps Net realized gains on financial instruments $ (12 ) Income Statement Relationship of Fair Value and Cash Flow Hedging A summary of the relationship between the effects of fair value and cash flow hedges on the total amount of income and expense presented in our consolidated statements of income for the three and nine months ended September 30, 2018 and 2017 is as follows: Classification and Amount of Gain (Loss) Recognized in Income on Fair Value and Cash Flow Hedging Relationships Three Months Ended September 30, 2018 Three Months Ended September 30, 2017 Nine Months Ended September 30, 2018 Nine Months Ended September 30, 2017 Net Realized Gains on Financial Instruments Interest Expense Net Realized Gains on Financial Instruments Interest Expense Net Realized Gains on Financial Instruments Interest Expense Net Realized Gains on Financial Instruments Interest Expense Total amount of income or expense in the income statement in which the effects of fair value or cash flow hedges are recorded $ 27 $ (188 ) $ 115 $ (150 ) $ 5 $ (564 ) $ 138 $ (575 ) (Loss) gain on fair value hedging relationships: Interest rate swaps Hedged items — — — — — (1 ) — — Derivatives designated as hedging instruments — — — — — 1 — — Loss on cash flow hedging relationships: Forward starting pay fixed swaps Amount of loss reclassified from accumulated other comprehensive loss into net income — (4 ) — (2 ) — (10 ) — (5 ) Amount of loss reclassified from accumulated other comprehensive loss into net income due to ineffectiveness and missed forecasted transactions — — — — — — (12 ) — Non-Hedging Derivatives A summary of the effect of non-hedging derivatives on our consolidated statements of income for the three and nine months ended September 30, 2018 and 2017 is as follows: Type of Non-Hedging Derivatives Income Statement Location of Gain (Loss) Recognized Derivative Gain (Loss) Recognized Three months ended September 30, 2018 Interest rate swaps Net realized gains on financial instruments $ — Options Net realized gains on financial instruments — Futures Net realized gains on financial instruments 2 Total $ 2 Three months ended September 30, 2017 Interest rate swaps Net realized gains on financial instruments $ — Options Net realized gains on financial instruments (13 ) Futures Net realized gains on financial instruments — Total $ (13 ) Nine months ended September 30, 2018 Interest rate swaps Net realized gains on financial instruments $ 15 Options Net realized gains on financial instruments — Futures Net realized gains on financial instruments 7 Total $ 22 Nine months ended September 30, 2017 Interest rate swaps Net realized gains on financial instruments $ (1 ) Options Net realized gains on financial instruments (34 ) Futures Net realized gains on financial instruments (2 ) Total $ (37 ) |

Fair Value Disclosures [Abstract] | |
Fair Value | Fair Value Assets and liabilities recorded at fair value in our consolidated balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Level inputs, as defined by FASB guidance for fair value measurements and disclosures, are as follows: Level Input Input Definition Level I Inputs are unadjusted, quoted prices for identical assets or liabilities in active markets at the measurement date. Level II Inputs other than quoted prices included in Level I that are observable for the asset or liability through corroboration with market data at the measurement date. Level III Unobservable inputs that reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. The following methods, assumptions and inputs were used to determine the fair value of each class of the following assets and liabilities recorded at fair value in our consolidated balance sheets: Cash equivalents: Cash equivalents primarily consist of highly rated money market funds with maturities of three months or less and are purchased daily at par value with specified yield rates. Due to the high ratings and short-term nature of the funds, we designate all cash equivalents as Level I. Fixed maturity securities, available-for-sale: Fair values of available-for-sale fixed maturity securities are based on quoted market prices, where available. These fair values are obtained primarily from third party pricing services, which generally use Level I or Level II inputs for the determination of fair value to facilitate fair value measurements and disclosures. Level II securities primarily include United States Government securities, corporate securities, securities from states, municipalities and political subdivisions, mortgage-backed securities and certain other asset-backed securities. For securities not actively traded, the pricing services may use quoted market prices of comparable instruments or discounted cash flow analyses, incorporating inputs that are currently observable in the markets for similar securities. We have controls in place to review the pricing services’ qualifications and procedures used to determine fair values. In addition, we periodically review the pricing services’ pricing methodologies, data sources and pricing inputs to ensure the fair values obtained are reasonable. Inputs that are often used in the valuation methodologies include, but are not limited to, broker quotes, benchmark yields, credit spreads, default rates and prepayment speeds. We also have certain fixed maturity securities, primarily corporate debt securities, which are designated Level III securities. For these securities, the valuation methodologies may incorporate broker quotes or discounted cash flow analyses using assumptions for inputs such as expected cash flows, benchmark yields, credit spreads, default rates and prepayment speeds that are not observable in the markets. Equity securities: Fair values of equity securities are generally designated as Level I and are based on quoted market prices. For certain equity securities, quoted market prices for the identical security are not always available and the fair value is estimated by reference to similar securities for which quoted prices are available. These securities are designated Level II. We also have certain equity securities, including private equity securities, for which the fair value is estimated based on each security’s current condition and future cash flow projections. Such securities are designated Level III. The fair values of these private equity securities are generally based on either broker quotes or discounted cash flow projections using assumptions for inputs such as the weighted-average cost of capital, long-term revenue growth rates and earnings before interest, taxes, depreciation and amortization, and/or revenue multiples that are not observable in the markets. Other invested assets, current: Other invested assets, current include securities held in rabbi trusts that are classified as trading. These securities are designated Level I securities, as fair values are based on quoted market prices. Securities lending collateral: Fair values of securities lending collateral are based on quoted market prices, where available. These fair values are obtained primarily from third party pricing services, which generally use Level I or Level II inputs for the determination of fair value, to facilitate fair value measurements and disclosures. Derivatives: Fair values are based on the quoted market prices by the financial institution that is the counterparty to the derivative transaction. We independently verify prices provided by the counterparties using valuation models that incorporate observable market inputs for similar derivative transactions. Derivatives are designated as Level II securities. Derivatives presented within the fair value hierarchy table below are presented on a gross basis and not on a master netting basis by counterparty. A summary of fair value measurements by level for assets and liabilities measured at fair value on a recurring basis at September 30, 2018 and December 31, 2017 is as follows: Level I Level II Level

Transfers between levels, if any, are recorded as of the beginning of the reporting period. There were no individually material transfers between levels during the three and nine months ended September 30, 2018 or 2017 . Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain circumstances. As disclosed in Note 3, “Business Acquisitions,” we completed our acquisition of America's 1st Choice on February 15, 2018. The preliminary values of net assets acquired in our acquisition of America's 1st Choice and resulting goodwill and other intangible assets were recorded at fair value primarily using Level III inputs. The majority of America's 1st Choice's assets acquired and liabilities assumed were recorded at their carrying values as of the respective date of acquisition, as their carrying values approximated their fair values due to their short-term nature. The preliminary fair values of intangible assets acquired in our acquisition of America's 1st Choice were internally estimated based on the income approach. The income approach estimates fair value based on the present value of the cash flows that the assets could be expected to generate in the future. We developed internal estimates for the expected cash flows and discount rate in the present value calculation. Other than the assets acquired and liabilities assumed in our acquisition of America's 1st Choice described above, there were no material assets or liabilities measured at fair value on a nonrecurring basis during the three and nine months ended September 30, 2018 or 2017 . Our valuation policy is determined by members of our treasury and accounting departments. Whenever possible, our policy is to obtain quoted market prices in active markets to estimate fair values for recognition and disclosure purposes. Where quoted market prices in active markets are not available, fair values are estimated using discounted cash flow analyses, broker quotes or other valuation techniques. These techniques are significantly affected by our assumptions, including discount rates and estimates of future cash flows. Potential taxes and other transaction costs are not considered in estimating fair values. Our valuation policy is generally to obtain only one quoted price for each security from third party pricing services, which are derived through recently reported trades for identical or similar securities making adjustments through the reporting date based upon available market observable information. When broker quotes are used, we generally obtain only one broker quote per security. As we are responsible for the determination of fair value, we perform a monthly analysis on the prices received from the pricing services to determine whether the prices are reasonable estimates of fair value. This analysis is performed by our internal treasury personnel who are familiar with our investment portfolios, the pricing services engaged and the valuation techniques and inputs used. Our analysis includes a review of month-to-month price fluctuations. If unusual fluctuations are noted in this review, we may obtain additional information from other pricing services to validate the quoted price. There were no adjustments to quoted market prices obtained from the pricing services during the three and nine months ended September 30, 2018 or 2017 . In addition to the preceding disclosures on assets recorded at fair value in the consolidated balance sheets, FASB guidance requires the disclosure of fair values for certain other financial instruments for which it is practicable to estimate fair value, whether or not such values are recognized in our consolidated balance sheets. Non-financial instruments such as real estate, property and equipment, other current assets, deferred income taxes, intangible assets and certain financial instruments, such as policy liabilities, are excluded from the fair value disclosures. Therefore, the fair value amounts cannot be aggregated to determine our underlying economic value. The carrying amounts reported in our consolidated balance sheets for cash, accrued investment income, premium receivables, self-funded receivables, other receivables, income taxes receivable/payable, unearned income, accounts payable and accrued expenses, security trades pending payable, securities lending payable and certain other current liabilities approximate fair value because of the short term nature of these items. These assets and liabilities are not listed in the table below. The following methods, assumptions and inputs were used to estimate the fair value of each class of financial instrument that is recorded at its carrying value in our consolidated balance sheets: Other invested assets, long-term: Other invested assets, long-term include primarily our investments in limited partnerships, joint ventures and other non-controlled corporations, as well as the cash surrender value of corporate-owned life insurance policies. Investments in limited partnerships, joint ventures and other non-controlled corporations are carried at our share in the entities’ undistributed earnings, which approximates fair value. The carrying value of corporate-owned life insurance policies represents the cash surrender value as reported by the respective insurer, which approximates fair value. Short-term borrowings: The fair value of our short-term borrowings is based on quoted market prices for the same or similar debt, or, if no quoted market prices were available, on the current market interest rates estimated to be available to us for debt of similar terms and remaining maturities. Long-term debt – commercial paper: The carrying amount for commercial paper approximates fair value, as the underlying instruments have variable interest rates at market value. Long-term debt – senior unsecured notes and surplus notes: The fair values of our notes are based on quoted market prices in active markets for the same or similar debt, or, if no quoted market prices are available, on the current observable market rates estimated to be available to us for debt of similar terms and remaining maturities. Long-term debt – convertible debentures: The fair value of our convertible debentures is based on the market price in the active private market in which the convertible debentures trade. A summary of the estimated fair values by level of each class of financial instrument that is recorded at its carrying value on our consolidated balance sheets at September 30, 2018 and December 31, 2017 is as follows: Carrying Value Estimated Fair Value Level I Level II Level III Total September 30, 2018 Assets: Other invested assets, long-term $ 3,572 $ — $ — $ 3,572 $ 3,572 Liabilities: Debt: Short-term borrowings 1,270 — 1,270 — 1,270 Commercial paper 750 — 750 — 750 Notes 17,160 — 17,178 — 17,178 Convertible debentures 239 — 1,363 — 1,363 December 31, 2017 Assets: Other invested assets, long-term $ 3,344 $ — $ — $ 3,344 $ 3,344 Liabilities: Debt: Short-term borrowings 1,275 — 1,275 — 1,275 Commercial paper 804 — 804 — 804 Notes 17,593 — 18,815 — 18,815 Convertible debentures 260 — 1,216 — 1,216 |

Income Tax Disclosure [Abstract] | |
Income Taxes | Income Taxes During the three months ended September 30, 2018 and 2017 , we recognized income tax expense of $282 and $372 , respectively, which represent effective tax rates of 22.7% and 33.2% , respectively. The decrease in income tax expense and effective tax rate was primarily due to the effect of the Tax Cuts and Jobs Act, which reduced the U.S. federal corporate income tax rate from 35% to 21% effective January 1, 2018 and required remeasurement of deferred tax assets and liabilities due to the revisions of 2017 provision estimates at the new rate . The decrease in income tax expense and effective tax rate was partially offset by the reinstatement of the non-tax deductible Health Insurance Provider Fee, or HIP Fee, for 2018, which resulted in additional income tax expense of $76 during the three months ended September 30, 2018 . During the nine months ended September 30, 2018 and 2017 , we recognized income tax expense of $1,200 and $1,228 , respectively, which represent effective tax rates of 26.5% and 32.0% , respectively. The decrease in income tax expense and effective tax rate was primarily due to the effect of the Tax Cuts and Jobs Act. The decrease in income tax expense and effective tax rate was partially offset by the reinstatement of the HIP Fee for 2018, which resulted in additional income tax expense of $243 during the nine months ended September 30, 2018 . The decrease in income tax expense and effective tax rate was also partially offset by the tax benefits we recognized during the nine months ended September 30, 2017 for prior acquisition costs incurred related to the terminated merger agreement with Cigna Corporation. At September 30, 2018, we have not completed our accounting for all of the tax effects of the Tax Cuts and Jobs Act. We have made a reasonable estimate of the effects and will continue to make and refine our calculations as additional analysis is completed. Our estimates may also be affected if additional interpretative guidance is issued regarding the Tax Cuts and Jobs Act. |

Debt Disclosure [Abstract] | |
Debt | Debt We generally issue senior unsecured notes for long-term borrowing purposes. At September 30, 2018 and December 31, 2017 , we had $17,135 and $16,329 , respectively, outstanding under these notes. On July 16, 2018, we repaid, at maturity, the $650 outstanding balance of our 2.300% senior unsecured notes. On January 15, 2018, we repaid, at maturity, the $625 outstanding balance of our 1.875% senior unsecured notes. In May 2015, we issued 25.0 Equity Units, in an aggregate principal amount of $1,250 . Each Equity Unit had a stated amount of $50 (whole dollars) and consisted of a purchase contract obligating the holder to purchase a certain number of shares of our common stock on May 1, 2018, subject to earlier termination or settlement, for a price in cash of $50 (whole dollars); and a 5% undivided beneficial ownership interest in $1,000 (whole dollars) principal amount of our 1.900% remarketable subordinated notes, or RSNs, due 2028. On May 1, 2018, we settled each of the Equity Units stock purchase contracts at a settlement rate of 0.2412 shares of our common stock, using a market value formula set forth in the Equity Units purchase contracts. This resulted in the issuance of approximately 6.0 shares. On March 2, 2018, we remarketed the RSNs and used the proceeds to purchase U.S. Treasury securities that were pledged to secure the stock purchase obligations of the holders of the Equity Units. The purchasers of the RSNs transferred the RSNs to us in exchange for $1,250 principal amount of our 4.101% senior notes due 2028, or the 2028 Notes, and a cash payment of $4 . We cancelled the RSNs upon receipt and recognized a loss on extinguishment of debt of $18 . At the remarketing, we also issued $850 aggregate principal amount of 4.550% notes due 2048, or the 2048 Notes, under our shelf registration statement. We used the proceeds from the 2048 Notes for working capital and general corporate purposes. We have an unsecured surplus note with an outstanding principal balance of $25 at both September 30, 2018 and December 31, 2017 . We have a senior revolving credit facility, or the Facility, with a group of lenders for general corporate purposes. The Facility provides credit up to $3,500 and matures on August 25, 2020 . There were no amounts outstanding under the Facility at any time during the nine months ended September 30, 2018 or at December 31, 2017 . We have two separate 364-day lines of credit with separate lenders for general corporate purposes. The facilities provide combined credit up to $500 . We had $450 outstanding under these lines of credit at September 30, 2018 and December 31, 2017 . We have an authorized commercial paper program of up to $2,500 , the proceeds of which may be used for general corporate purposes. At September 30, 2018 and December 31, 2017 , we had $750 and $804 , respectively, outstanding under this program. We have outstanding senior unsecured convertible debentures due 2042, or the Debentures, which are governed by an indenture between us and The Bank of New York Mellon Trust Company, N.A., as trustee. We have accounted for the Debentures in accordance with the cash conversion guidance in FASB guidance for debt with conversion and other options. As a result, the value of the embedded conversion option has been bifurcated from its debt host and recorded as a component of additional paid-in capital (net of deferred taxes and equity issuance costs) in our consolidated balance sheets. During the nine months ended September 30, 2018 , $35 aggregate principal amount of the Debentures were surrendered for conversion by certain holders in accordance with the terms and provisions of the indenture. We elected to settle the excess of the principal amount of the conversions with cash for total payments of $118 . We recognized a gain on the extinguishment of debt related to the Debentures of $1 , based on the fair values of the debt on the conversion settlement dates. The following table summarizes at September 30, 2018 the related balances, conversion rate and conversion price of the Debentures: Outstanding principal amount $ 361 Unamortized debt discount $ 118 Net debt carrying amount $ 239 Equity component carrying amount $ 131 Conversion rate (shares of common stock per $1,000 of principal amount) 13.8258 Effective conversion price (per $1,000 of principal amount) $ 72.3280 We had $820 and $825 in outstanding short-term borrowings from various Federal Home Loan Banks, or FHLBs, at September 30, 2018 and December 31, 2017 with fixed interest rates of 2.149% and 1.386% respectively. All debt is a direct obligation of Anthem, Inc., except for the surplus note, the FHLB borrowings, and the 364-day lines of credit. |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments And Contingencies | Commitments and Contingencies Litigation and Regulatory Proceedings In the ordinary course of business, we are defendants in, or parties to, a number of pending or threatened legal actions or proceedings. To the extent a plaintiff or plaintiffs in the following cases have specified in their complaint or in other court filings the amount of damages being sought, we have noted those alleged damages in the descriptions below. With respect to the cases described below, we contest liability and/or the amount of damages in each matter and believe we have meritorious defenses. Where available information indicates that it is probable that a loss has been incurred as of the date of the consolidated financial statements and we can reasonably estimate the amount of that loss, we accrue the estimated loss by a charge to income. In many proceedings, however, it is difficult to determine whether any loss is probable or reasonably possible. In addition, even where loss is possible or an exposure to loss exists in excess of the liability already accrued with respect to a previously identified loss contingency, it is not always possible to reasonably estimate the amount of the possible loss or range of loss. With respect to many of the proceedings to which we are a party, we cannot provide an estimate of the possible losses, or the range of possible losses in excess of the amount, if any, accrued, for various reasons, including but not limited to some or all of the following: (i) there are novel or unsettled legal issues presented, (ii) the proceedings are in early stages, (iii) there is uncertainty as to the likelihood of a class being certified or decertified or the ultimate size and scope of the class, (iv) there is uncertainty as to the outcome of pending appeals or motions, (v) there are significant factual issues to be resolved, and/or (vi) in many cases, the plaintiffs have not specified damages in their complaint or in court filings. For those legal proceedings where a loss is probable, or reasonably possible, and for which it is possible to reasonably estimate the amount of the possible loss or range of losses, we currently believe that the range of possible losses, in excess of established reserves is, in the aggregate, from $0 to approximately $ 250 at September 30, 2018 . This estimated aggregate range of reasonably possible losses is based upon currently available information taking into account our best estimate of such losses for which such an estimate can be made. Blue Cross Blue Shield Antitrust Litigation We are a defendant in multiple lawsuits that were initially filed in 2012 against the BCBSA and Blue Cross and/or Blue Shield licensees, or Blue plans, across the country. The cases were consolidated into a single multi-district proceeding captioned In re Blue Cross Blue Shield Antitrust Litigation that is pending in the United States District Court for the Northern District of Alabama, or the Court. Generally, the suits allege that the BCBSA and the Blue plans have conspired to horizontally allocate geographic markets through license agreements, best efforts rules that limit the percentage of non-Blue revenue of each plan, restrictions on acquisitions rules governing the BlueCard and National Accounts programs and other arrangements in violation of the Sherman Antitrust Act, or Sherman Act, and related state laws. The cases were brought by two putative nationwide classes of plaintiffs, health plan subscribers and providers, and actions filed in Alabama, Arkansas, California, Florida, Hawaii, Illinois, Indiana, Kansas, Kansas City, Louisiana, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, New Hampshire, North Carolina, North Dakota, Oklahoma, Pennsylvania, South Dakota, Rhode Island, South Carolina, Tennessee, Texas, Vermont and Virginia have been consolidated into the multi-district proceeding. In response to cross motions for partial summary judgment by plaintiffs and defendants, the Court issued an order in April 2018 determining that the defendants’ aggregation of geographic market allocations and output restrictions are to be analyzed under a per se standard of review, and the BlueCard program and other alleged Section 1 Sherman Act violations are to be analyzed under the rule of reason standard of review. The Court also found that there remain genuine issues of material fact as to whether defendants operate as a single entity with regard to the enforcement of the Blue Cross Blue Shield trademarks. In June 2018, in response to a motion filed by the defendants, the Court certified its April order for interlocutory appeal to the Eleventh Circuit Court of Appeals. Also in June 2018, the defendants filed, with the Eleventh Circuit Court of Appeals, a petition for permission to appeal the April order, which Plaintiffs opposed. The defendants’ petition remains pending. No dates have been set for either the final pretrial conferences or trials in these actions. We intend to vigorously defend these suits; however, their ultimate outcome cannot be presently determined. Blue Cross of California Taxation Litigation In July 2013, our California affiliate Blue Cross of California (doing business as Anthem Blue Cross), or BCC, was named as a defendant in a California taxpayer action filed in Los Angeles County Superior Court, captioned Michael D. Myers v. State Board of Equalization, et al. This action was brought under a California statute that permits an individual taxpayer to sue a governmental agency when the taxpayer believes the agency has failed to enforce governing law. Plaintiff contends that BCC, a licensed Health Care Service Plan, or HCSP, is an “insurer” for purposes of taxation despite acknowledging it is not an “insurer” under regulatory law. At the time, under California law, “insurers” were required to pay a gross premiums tax, or GPT, calculated as 2.35% on gross premiums. As a licensed HCSP, BCC has paid the California Corporate Franchise Tax, or CFT, the tax paid by California businesses generally. Plaintiff contends that BCC must pay the GPT rather than the CFT, and seeks a writ of mandate directing the taxing agencies to collect the GPT and an order requiring BCC to pay GPT back taxes, interest, and penalties, for the eight-year period prior to the filing of the complaint. In March 2018, the Court denied BCC’s motion for judgment on the pleadings and similar motions brought by other entities. We filed a writ of mandate in the California Court of Appeal. The Court of Appeal accepted our writ, and we anticipate that a hearing on our writ will occur in late 2018. Because GPT is constitutionally imposed in lieu of certain other taxes, BCC has filed protective tax refund claims with the City of Los Angeles, the California Department of Health Care Services and the Franchise Tax Board to protect its rights to recover certain taxes previously paid should BCC eventually be determined to be subject to the GPT for the same tax periods. BCC intends to vigorously defend this suit; however, its ultimate outcome cannot be presently determined. Express Scripts, Inc. Pharmacy Benefit Management Litigation In March 2016, we filed a lawsuit against Express Scripts, Inc., or Express Scripts, our vendor for pharmacy benefit management, or PBM, services, captioned Anthem, Inc. v. Express Scripts, Inc. , in the U.S. District Court for the Southern District of New York. The lawsuit seeks to recover over $14,800 in damages for pharmacy pricing that is higher than competitive benchmark pricing under the agreement between the parties, or PBM Agreement, over $158 in damages related to operational breaches, as well as various declarations under the PBM Agreement between the parties, including that Express Scripts: (i) breached its obligation to negotiate in good faith and to agree in writing to new pricing terms; (ii) is required to provide competitive benchmark pricing to us through the term of the PBM Agreement; (iii) has breached the PBM Agreement and that we can terminate the PBM Agreement; and (iv) is required under the PBM Agreement to provide post-termination services, at competitive benchmark pricing, for one year following any termination. Express Scripts has disputed our contractual claims and is seeking declaratory judgments: (i) regarding the timing of the periodic pricing review under the PBM Agreement; (ii) that it has no obligation to ensure that we receive any specific level of pricing, that we have no contractual right to any change in pricing under the PBM Agreement and that its sole obligation is to negotiate proposed pricing terms in good faith; and (iii) that we do not have the right to terminate the PBM Agreement. In the alternative, Express Scripts claims that we have been unjustly enriched by its payment of $4,675 at the time of the PBM Agreement. In March 2017, the court granted our motion to dismiss Express Scripts’ counterclaims for (i) breach of the implied covenant of good faith and fair dealing, and (ii) unjust enrichment with prejudice. The only remaining claims are for breach of contract and declaratory relief. We intend to vigorously pursue our claims and defend against any counterclaims, which we believe are without merit; however, the ultimate outcome cannot be presently determined. ERISA Litigation We are a defendant in a class action lawsuit that was initially filed in June 2016 against Anthem, Inc. and Express Scripts, which has been consolidated into a single multi-district lawsuit captioned In Re Express Scripts/Anthem ERISA Litigation, in the U.S. District Court for the Southern District of New York. The consolidated complaint was filed by plaintiffs against Express Scripts and us on behalf of all persons who are participants in or beneficiaries of any ERISA or non-ERISA healthcare plan from December 1, 2009 to the present in which we provided prescription drug benefits through the PBM Agreement with Express Scripts and paid a percentage based co-insurance payment in the course of using that prescription drug benefit. The plaintiffs allege that we breached our duties, either under ERISA or with respect to the implied covenant of good faith and fair dealing implied in the health plans, (i) by failing to adequately monitor Express Scripts’ pricing under the PBM Agreement and (ii) by placing our own pecuniary interest above the best interests of our insureds by allegedly agreeing to higher pricing in the PBM Agreement in exchange for the purchase price for our NextRx PBM business, and (iii) with respect to the non-ERISA members, by negotiating and entering into the PBM Agreement with Express Scripts that was allegedly detrimental to the interests of such non-ERISA members. Plaintiffs seek to hold us and Express Scripts jointly and severally liable and to recover all losses suffered by the proposed class, equitable relief, disgorgement of alleged ill-gotten gains, injunctive relief, attorney’s fees and costs and interest. In April 2017, we filed a motion to dismiss the claims brought against us, and it was granted, without prejudice, in January 2018. Plaintiffs filed a notice of appeal with the United States Court of Appeals for the Second Circuit, which was heard in October 2018. We intend to vigorously defend this suit; however, its ultimate outcome cannot be presently determined. Cigna Corporation Merger Litigation In July 2015, we and Cigna Corporation, or Cigna, announced that we entered into the Agreement and Plan of Merger, or Cigna Merger Agreement, pursuant to which we would acquire all outstanding shares of Cigna. In July 2016, the U.S. Department of Justice, or DOJ, along with certain state attorneys general, filed a civil antitrust lawsuit in the U.S. District Court for the District of Columbia, or District Court, seeking to block the merger. In February 2017, Cigna purported to terminate the Cigna Merger Agreement and commenced litigation against us in the Delaware Court of Chancery, or Delaware Court, seeking damages, including the $1,850 termination fee pursuant to the terms of the Cigna Merger Agreement, and a declaratory judgment that its purported termination of the Cigna Merger Agreement was lawful, among other claims, which is captioned Cigna Corp. v. Anthem Inc. Also in February 2017, we initiated our own litigation against Cigna in the Delaware Court seeking a temporary restraining order to enjoin Cigna from terminating the Cigna Merger Agreement, specific performance compelling Cigna to comply with the Cigna Merger Agreement and damages, which is captioned Anthem Inc. v. Cigna Corp . In April 2017, the U.S. Circuit Court of Appeals for the District of Columbia affirmed the ruling of the District Court, which blocked the merger. In May 2017, after the Delaware Court denied our motion to enjoin Cigna from terminating the Cigna Merger Agreement, we delivered to Cigna a notice terminating the Cigna Merger Agreement. The litigation in Delaware is ongoing with trial scheduled to commence in February 2019. We believe Cigna’s allegations are without merit and we intend to vigorously pursue our claims and defend against Cigna’s allegations; however, the ultimate outcome of our litigation with Cigna cannot be presently determined. In October 2018, a shareholder filed a derivative lawsuit in Marion County Superior Court, captioned Henry Bittmann, Derivatively, et al. v. Joseph R Swedish, et al. , on behalf of Anthem and its shareholders against certain current and former directors and executives alleging breaches of fiduciary duties, unjust enrichment and corporate waste associated with the Cigna Merger Agreement. We intend to vigorously defend this lawsuit; however, its ultimate outcome cannot be presently determined. U.S. Department of Justice (DOJ) Civil Investigative Demands Beginning in December 2016, the DOJ has issued civil investigative demands to us to discover information about our chart review and risk adjustment programs under Parts C and D of the Medicare Program. We understand the DOJ is investigating the programs of other Medicare Advantage health plans, along with providers and vendors. We continue to cooperate with the DOJ’s investigation, and the ultimate outcome cannot presently be determined. Cyber Attack Regulatory Proceedings and Litigation In February 2015, we reported that we were the target of a sophisticated external cyber attack. The attackers gained unauthorized access to certain of our information technology systems and obtained personal information related to many individuals and employees, such as names, birth dates, healthcare identification/social security numbers, street addresses, email addresses, phone numbers and employment information, including income data. To date, there is no evidence that credit card or medical information, such as claims, test results or diagnostic codes, were targeted, accessed or obtained, although no assurance can be given that we will not identify additional information that was accessed or obtained. Upon discovery of the cyber attack, we took immediate action to remediate the security vulnerability and retained a cybersecurity firm to evaluate our systems and identify solutions based on the evolving landscape. We have provided credit monitoring and identity protection services to those who have been affected by this cyber attack. We have continued to implement security enhancements since this incident. We have incurred expenses subsequent to the cyber attack to investigate and remediate this matter and expect to continue to incur expenses of this nature in the foreseeable future. We recognize these expenses in the periods in which they are incurred. Federal and state agencies, including state insurance regulators, state attorneys general, the Health and Human Services, or HHS, Office of Civil Rights and the Federal Bureau of Investigation, are investigating, or have investigated, events related to the cyber attack, including how it occurred, its consequences and our responses. In connection with the resolution of the National Association of Insurance Commissioners’ multistate targeted market conduct and financial exam in December 2016, we agreed to provide a customized credit protection program, equivalent to a credit freeze, for our members who were under the age of eighteen on January 27, 2015. No fines or penalties were imposed on us. In October 2018, we resolved the investigation by the HHS Office of Civil Rights. The resolution included a monetary settlement along with an agreement to a two-year Corrective Action Plan. Additionally, an ongoing investigation by a multi-state group of Attorneys General remains outstanding. Although we are cooperating in these investigations, we may be subject to additional fines or other obligations, which may have an adverse effect on how we operate our business and an adverse effect on our results of operations and financial condition. Civil class actions were filed in various federal and state courts by current or former members and others seeking damages that they alleged arose from the cyber-attack. In June 2015, the Judicial Panel on Multidistrict Litigation entered an order transferring the consolidated civil actions to the U.S. District Court for the Northern District of California, or the U.S. District Court in a matter captioned In Re Anthem, Inc. Data Breach Litigation . The parties agreed to settle plaintiffs’ claims on a class-wide basis for a total settlement payment of $115 . In August 2017, the U.S. District Court issued an order of preliminary approval of the settlement. The U.S. District Court held hearings on plaintiffs’ motion for final approval and class counsel’s fee petition in February and June 2018 and appointed a special master to review class counsel’s fee petition. Final approval of the settlement was granted by the U.S. District Court in August 2018. A number of appeals have since been filed with the Ninth Circuit Court of Appeals by class-member objections challenging that approval, several of which have been resolved. The three state court cases related to the cyber attack that were proceeding outside of this multidistrict litigation have been resolved and dismissed with prejudice. We have contingency plans and insurance coverage for certain expenses and potential liabilities of this nature and will pursue coverage for all applicable losses; however, the ultimate outcome of our pursuit of insurance coverage cannot be presently determined. We intend to vigorously defend the remaining regulatory actions related to the cyber attack; however, their ultimate outcome cannot be presently determined. Other Contingencies From time to time, we and certain of our subsidiaries are parties to various legal proceedings, many of which involve claims for coverage encountered in the ordinary course of business. We, like HMOs and health insurers generally, exclude certain healthcare and other services from coverage under our HMO, PPO and other plans. We are, in the ordinary course of business, subject to the claims of our enrollees arising out of decisions to restrict or deny reimbursement for uncovered services. The loss of even one such claim, if it results in a significant punitive damage award, could have a material adverse effect on us. In addition, the risk of potential liability under punitive damage theories may increase significantly the difficulty of obtaining reasonable settlements of coverage claims. In addition to the lawsuits described above, we are also involved in other pending and threatened litigation of the character incidental to our business, and are from time to time involved as a party in various governmental investigations, audits, reviews and administrative proceedings. These investigations, audits, reviews and administrative proceedings include routine and special inquiries by state insurance departments, state attorneys general, the U.S. Attorney General and subcommittees of the U.S. Congress. Such investigations, audits, reviews and administrative proceedings could result in the imposition of civil or criminal fines, penalties, other sanctions and additional rules, regulations or other restrictions on our business operations. Any liability that may result from any one of these actions, or in the aggregate, could have a material adverse effect on our consolidated financial position or results of operations. Contractual Obligations and Commitments Express Scripts, through our PBM Agreement, is the exclusive provider of certain PBM services to our plans, excluding certain of our subsidiaries that have exclusive agreements with different PBM service providers. The initial term of this PBM Agreement expires on December 31, 2019. Under the PBM Agreement, the Express Scripts PBM services include, but are not limited to, pharmacy network management, mail order and specialty drug fulfillment, claims processing, rebate management and specialty pharmaceutical management services. Accordingly, the PBM Agreement contains certain financial and operational requirements obligating both Express Scripts and us. Express Scripts’ primary obligations relate to the performance of such services in a compliant manner and meeting certain pricing guarantees and performance standards. Our primary responsibilities relate to formulary management, product and benefit design, provision of data, payment for services, certain minimum volume requirements and oversight. The failure by either party to meet the respective requirements could potentially serve as a basis for financial penalties or early termination of the PBM Agreement. In March 2016, we filed a lawsuit against Express Scripts seeking to recover damages for pharmacy pricing that is higher than competitive benchmark pricing, damages related to operational breaches, as well as various declarations under the PBM Agreement between the parties. For additional information regarding this lawsuit, refer to the Litigation and Regulatory Proceedings section above. We believe we have appropriately recognized all rights and obligations under this PBM Agreement at September 30, 2018 . |

Capital [Abstract] | |
Capital Stock | Capital Stock Use of Capital – Dividends and Stock Repurchase Program We regularly review the appropriate use of capital, including acquisitions, common stock and debt security repurchases and dividends to shareholders. The declaration and payment of any dividends or repurchases of our common stock or debt is at the discretion of our Board of Directors and depends upon our financial condition, results of operations, future liquidity needs, regulatory and capital requirements and other factors deemed relevant by our Board of Directors. A summary of the cash dividend activity for the nine months ended September 30, 2018 and 2017 is as follows: Declaration Date Record Date Payment Date Cash Dividend per Share Total Nine Months Ended September 30, 2018 January 30, 2018 March 9, 2018 March 23, 2018 $0.75 $ 192 April 24, 2018 June 8, 2018 June 25, 2018 $0.75 $ 196 July 24, 2018 September 10, 2018 September 25, 2018 $0.75 $ 195 Nine Months Ended September 30, 2017 February 22, 2017 March 10, 2017 March 24, 2017 $0.65 $ 172 April 27, 2017 June 9, 2017 June 23, 2017 $0.65 $ 172 July 25, 2017 September 8, 2017 September 25, 2017 $0.70 $ 181 On October 30, 2018, our Audit Committee declared a fourth quarter 2018 dividend to shareholders of $0.75 per share, payable on December 21, 2018 to shareholders of record at the close of business on December 5, 2018 . Under our Board of Directors’ authorization, we maintain a common stock repurchase program. On December 7, 2017, the Board of Directors authorized a $5,000 increase to the common stock repurchase program. Repurchases may be made from time to time at prevailing market prices, subject to certain restrictions on volume, pricing and timing. The repurchases are effected from time to time in the open market, through negotiated transactions, including accelerated share repurchase agreements, and through plans designed to comply with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended. Our stock repurchase program is discretionary, as we are under no obligation to repurchase shares. We repurchase shares under the program when we believe it is a prudent use of capital. The excess cost of the repurchased shares over par value is charged on a pro rata basis to additional paid-in capital and retained earnings. A summary of common stock repurchases from October 1, 2018 through October 18, 2018 (subsequent to September 30, 2018 ) and for the nine months ended September 30, 2018 and 2017 is as follows: October 1, 2018 Nine Months Ended September 30 2018 2017 Shares repurchased 0.3 5.0 8.7 Average price per share $ 274.32 $ 240.15 $ 186.80 Aggregate cost $ 95 $ 1,192 $ 1,635 Authorization remaining at the end of the period $ 5,891 $ 5,986 $ 2,541 Equity Units In May 2015, we issued 25.0 Equity Units in an aggregate principal amount of $1,250 . Each Equity Unit contained a purchase contract obligating the holder to purchase a certain number of shares of our common stock on May 1, 2018, subject to earlier termination or settlement. On May 1, 2018, we issued approximately 6.0 shares of our common stock pursuant to the purchase contract portion of the Equity Units, and we received $1,250 in proceeds from the holders of the Equity Units for such common stock. The number of shares purchased was determined using a market value formula set forth in the Equity Units purchase contracts. For additional information relating to the Equity Units, see Note 10, “Debt” of this Form 10-Q and Note 12, “Debt,” to our audited consolidated financial statements as of and for the year ended December 31, 2017 included in our 2017 Annual Report on Form 10-K.

These grants have been included in the activity shown above, but will be subject to adjustment at the end of 2020 based on results in the three year period. During the nine months ended September 30, 2018 , we granted an additional 0.2 restricted stock units, associated with our 2015 grants, that were earned as a result of satisfactory completion of performance measures between 2015 and 2017. These grants and vested shares have been included in the activity shown above. Fair Value We use a binomial lattice valuation model to estimate the fair value of all stock options granted. For a more detailed discussion of our stock incentive plan fair value methodology, see Note 14, “Capital Stock,” to our audited consolidated financial statements as of and for the year ended December 31, 2017 included in our 2017 Annual Report on Form 10-K. The following weighted-average assumptions were used to estimate the fair values of options granted during the nine months ended September 30, 2018 and 2017 : Nine Months Ended September 30 2018 2017 Risk-free interest rate 2.90 % 2.31 % Volatility factor 30.00 % 32.00 % Quarterly dividend yield 0.323 % 0.397 % Weighted-average expected life (years) 3.70 4.00 The following weighted-average fair values per option or share were determined for the nine months ended September 30, 2018 and 2017 : Nine Months Ended September 30 2018 2017 Options granted during the period $ 55.44 $ 40.84 Restricted stock awards granted during the period 233.27 173.62 |

Earnings Per Share | Earnings per Share The denominator for basic and diluted earnings per share for the three and nine months ended September 30, 2018 and 2017 is as follows: Three Months Ended Nine Months Ended 2018 2017 2018 2017 Denominator for basic earnings per share – weighted-average shares 259.5 260.5 258.0 263.2 Effect of dilutive securities – employee stock options, nonvested restricted stock awards, convertible debentures and equity units 5.9 6.5 6.3 6.2 Denominator for diluted earnings per share 265.4 267.0 264.3 269.4 During the three months ended September 30, 2018 and 2017 , there were no stock options that were anti-dilutive or excluded from the denominator for diluted earnings per share. During the nine months ended September 30, 2018 and 2017 , weighted-average shares related to certain stock options of 0.4 and 0.5 , respectively, were excluded from the denominator for diluted earnings per share because the stock options were anti-dilutive. The Equity Unit purchase contracts were settled in May 2018, and approximately 6.0 shares of our common stock were issued and included in the basic earnings per share calculation. During the three and nine months ended September 30, 2018 , we issued restricted stock units under our stock incentive plans of 0.0 and 0.9 , respectively, 0.3 of which vesting is contingent upon us meeting specified annual earnings targets for the three year period of 2018 through 2020. During the three and nine months ended September 30, 2017 , we issued restricted stock units under our stock incentive plans of 0.2 and 0.8 , respectively, 0.4 of which vesting is contingent upon us meeting specified annual earnings targets for the three year period of 2017 through 2019. The contingent restricted stock units have been excluded from the denominator for diluted earnings per share and will be included only if and when the contingency is met. |

Financial data by reportable segment for the three and nine months ended September 30, 2018 and 2017 is as follows: Commercial & Specialty Business Government Business Other Total Three Months Ended September 30, 2018 Operating revenue $ 9,128 $ 13,841 $ 11 $ 22,980 Operating gain (loss) 833 466 (50 ) 1,249 Three Months Ended September 30, 2017 Operating revenue $ 10,052 $ 12,037 $ 8 $ 22,097 Operating gain (loss) 535 457 (10 ) 982 Nine Months Ended September 30, 2018 Operating revenue $ 27,357 $ 40,647 $ 33 $ 68,037 Operating gain (loss) 3,295 1,494 (113 ) 4,676 Nine Months Ended September 30, 2017 Operating revenue $ 30,651 $ 35,946 $ 17 $ 66,614 Operating gain (loss) 2,805 1,069 (80 ) 3,794 The major product revenues for each of the reportable segments for the three and nine months ended September 30, 2018 and 2017 are as follows: Three Months Ended Nine Months Ended 2018 2017 2018 2017 Commercial & Specialty Business Managed care products $ 7,377 $ 8,478 $ 22,212 $ 25,815 Managed care services 1,334 1,196 3,918 3,651 Dental/Vision products and services 306 305 914 913 Other 111 73 313 272 Total Commercial & Specialty Business 9,128 10,052 27,357 30,651 Government Business Managed care products 13,695 11,934 40,276 35,619 Managed care services 146 103 371 327 Total Government Business 13,841 12,037 40,647 35,946 Other Other 11 8 33 17 Total product revenues $ 22,980 $ 22,097 $ 68,037 $ 66,614 The classification between managed care products and managed care services in the above table primarily distinguishes between the levels of risk assumed. Managed care products represent insurance products where we bear the insurance risk, whereas managed care services represent product offerings where we provide claims adjudication and other administrative services to the customer, but the customer principally bears the insurance risk. A reconciliation of reportable segments’ operating revenues to the amounts of total revenues included in our consolidated statements of income for the three and nine months ended September 30, 2018 and 2017 is as follows: Three Months Ended Nine Months Ended 2018 2017 2018 2017 Reportable segments’ operating revenues $ 22,980 $ 22,097 $ 68,037 $ 66,614 Net investment income 250 220 708 628 Net realized gains on financial instruments 27 115 5 138 Other-than-temporary impairment losses recognized in income (6 ) (6 ) (18 ) (21 ) Total revenues $ 23,251 $ 22,426 $ 68,732 $ 67,359 A reconciliation of reportable segments’ operating gain to income before income tax expense included in our consolidated statements of income for the three and nine months ended September 30, 2018 and 2017 is as follows: Three Months Ended Nine Months Ended 2018 2017 2018 2017 Reportable segments’ operating gain $ 1,249 $ 982 $ 4,676 $ 3,794 Net investment income 250 220 708 628 Net realized gains on financial instruments 27 115 5 138 Other-than-temporary impairment losses recognized in income (6 ) (6 ) (18 ) (21 ) Interest expense (188 ) (150 ) (564 ) (575 ) Amortization of other intangible assets (91 ) (42 ) (265 ) (124 ) Gain (loss) on extinguishment of debt 1 — (17 ) — Income before income tax expense $ 1,242 $ 1,119 $ 4,525 $ 3,840 |

Accounting Policies [Abstract] | |
Basis of Presentation | Basis of Presentation: The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP, for interim financial reporting. Accordingly, they do not include all of the information and footnotes required by GAAP for annual financial statements. We have omitted certain footnote disclosures that would substantially duplicate the disclosures in our 2017 Annual Report on Form 10-K, unless the information contained in those disclosures materially changed or is required by GAAP. Certain prior year amounts have been reclassified to conform to the current year presentation or adjusted to conform to the current year rounding convention. In the opinion of management, all adjustments, including normal recurring adjustments, necessary for a fair statement of the consolidated financial statements as of and for the three and nine months ended September 30, 2018 and 2017 have been recorded. The results of operations for the three and nine months ended September 30, 2018 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2018 , or any other period. These unaudited consolidated financial statements should be read in conjunction with our audited consolidated financial statements as of and for the year ended December 31, 2017 included in our 2017 Annual Report on Form 10-K. |
Foreign Currency | Certain of our subsidiaries operate outside of the United States and have functional currencies other than the U.S. dollar, or USD. We translate the assets and liabilities of those subsidiaries to USD using the exchange rate in effect at the end of the period. We translate the revenues and expenses of those subsidiaries to USD using the average exchange rates in effect during the period. The net effect of these translation adjustments is included in “Foreign currency translation adjustments” in our consolidated statements of comprehensive income. |
Cash and Cash Equivalents | Additionally, we control a number of bank accounts that are used exclusively to hold customer funds for the administration of customer benefits and have cash and cash equivalents on deposit to meet certain regulatory requirements. These amounts totaled $243 and $182 at September 30, 2018 and December 31, 2017 , respectively and are included in the cash and cash equivalents line on our consolidated balance sheets. |
Revenue Recognition | Revenue Recognition: Premiums for fully-insured contracts are recognized as revenue over the period insurance coverage is provided, and, if applicable, net of amounts recognized for the minimum medical loss ratio rebates or contractual or government-mandated premium stabilization programs. Administrative fees and other revenue includes revenue from certain group contracts that provide for the group to be at risk for all, or with supplemental insurance arrangements, a portion of their claims experience. We charge these self-funded groups an administrative fee, which is based on the number of members in a group or the group’s claim experience. Under our self-funded arrangements, revenue is recognized as administrative services are performed, and benefit payments under these programs are excluded from benefit expense. For additional information about our revenues, see Note 2, “Basis of Presentation and Significant Accounting Policies” and Note 19, “Segment Information,” to our audited consolidated financial statements as of and for the year ended December 31, 2017 included in our 2017 Annual Report on Form 10-K. In addition, see Note 15, “Segment Information,” herein for the disaggregation of revenues by segments and products. Premium and self-funded receivables include the uncollected amounts from insured groups, individuals and government programs. Premium receivables are reported net of an allowance for doubtful accounts of $312 and $302 at September 30, 2018 and December 31, 2017 , respectively. Self-funded receivables are reported net of an allowance for doubtful accounts of $40 and $153 at September 30, 2018 and December 31, 2017 , respectively. For our non-fully-insured contracts, we had no material contract assets, contract liabilities or deferred contract costs recorded on our consolidated balance sheet at September 30, 2018 . For the three and nine months ended September 30, 2018 , revenue recognized from performance obligations related to prior periods, such as due to changes in transaction price, was not material. For contracts that have an original expected duration of greater than one year, revenue expected to be recognized in future periods related to unfulfilled contractual performance obligations and contracts with variable consideration related to undelivered performance obligations is not material. |
Recently Adopted Accounting Guidance | Recently Adopted Accounting Guidance: In February 2018, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update No. 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income , or ASU 2018-02. On December 22, 2017, the federal government enacted a tax bill, H.R.1, An act to provide for reconciliation pursuant to titles II and V of the concurrent resolution on the budget for fiscal year 2018 , or the Tax Cuts and Jobs Act. The Tax Cuts and Jobs Act contains significant changes to corporate taxation, including, but not limited to, reducing the U.S. federal corporate income tax rate from 35% to 21% and modifying or limiting many business deductions. Current FASB guidance requires adjustments of deferred taxes due to a change in the federal corporate income tax rate to be included in income from operations. As a result, the tax effects of items within accumulated other comprehensive loss did not reflect the appropriate tax rate. The amendments in ASU 2018-02 allow a reclassification from accumulated other comprehensive loss to retained earnings for stranded tax effects resulting from the change in the federal corporate income tax rate. We adopted the amendments in ASU 2018-02 for our interim and annual reporting periods beginning on January 1, 2018 and reclassified $91 of stranded tax effects from accumulated other comprehensive loss to retained earnings on our consolidated balance sheet. The adoption of ASU 2018-02 did not have any impact on our results of operations or cash flows. In May 2017, the FASB issued Accounting Standards Update No. 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting , or ASU 2017-09. This update provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. We adopted ASU 2017-09 on January 1, 2018. The guidance has been and will be applied prospectively to awards modified on or after the adoption date. The adoption of ASU 2017-09 did not have any impact on our consolidated financial position, results of operations or cash flows. In March 2017, the FASB issued Accounting Standards Update No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost , or ASU 2017-07. This amendment requires entities to disaggregate the service cost component from the other components of the benefit cost and present the service cost component in the same income statement line item as other employee compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. Certain of our defined benefit plans have previously been frozen, resulting in no annual service costs, and the remaining service costs for our non-frozen plan are not material. We adopted ASU 2017-07 on January 1, 2018 and it did not have a material impact on our results of operations, cash flows or consolidated financial position. In December 2016, the FASB issued Accounting Standards Update No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers , or ASU 2016-20 . In May 2016, the FASB issued Accounting Standards Update No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients , or ASU 2016-12. In April 2016, the FASB issued Accounting Standards Update No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing , or ASU 2016-10. In March 2016, the FASB issued Accounting Standards Update No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross verses Net) , or ASU 2016-08. These updates provide additional clarification and implementation guidance on the previously issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) , or ASU 2014-09. Collectively, these updates require a company to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. These updates supersede almost all existing revenue recognition guidance under GAAP, with certain exceptions, including an exception for our premium revenues, which are recorded on the Premiums line item on our consolidated statements of income and will continue to be accounted for in accordance with the provisions of Accounting Standards Codification, or ASC, Topic 944, Financial Services - Insurance . Our administrative service and other contracts that are subject to these Accounting Standards Updates are recorded in the Administrative fees and other revenue line item on our consolidated statements of income and represents approximately 6% of our consolidated total operating revenue. We adopted these standards on January 1, 2018 using the modified retrospective approach. The adoption of these standards did not have a material impact on our beginning retained earnings, results of operations, cash flows or consolidated financial position. In November 2016, the FASB issued Accounting Standards Update No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, or ASU 2016-18. This update amends ASC Topic 230 to add and clarify guidance on the classification and presentation of restricted cash in the statement of cash flows. The guidance requires entities to show the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. We adopted ASU 2016-18 on January 1, 2018 using a retrospective approach. The adoption of ASU 2016-18 did not have a material impact on our consolidated statements of cash flows and did not impact our results of operations or consolidated financial position. In August 2016, the FASB issued Accounting Standards Update No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, or ASU 2016-15. This update addresses the presentation and classification on the statement of cash flows for eight specific items, with the objective of reducing existing diversity in practice in how certain cash receipts and cash payments are presented and classified. We adopted ASU 2016-15 on January 1, 2018. The adoption of ASU 2016-15 did not have a material impact on our consolidated statements of cash flows, results of operations or consolidated financial position. In January 2016, the FASB issued Accounting Standards Update No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities , or ASU 2016-01. The amendments in ASU 2016-01 change the accounting for non-consolidated equity investments that are not accounted for under the equity method of accounting by requiring changes in fair value to be recognized in income. Additionally, ASU 2016-01 simplifies the impairment assessment of equity investments without readily determinable fair values; requires entities to use the exit price when estimating the fair value of financial instruments; and modifies various presentation disclosure requirements for financial instruments. We adopted ASU 2016-01 on January 1, 2018 as a cumulative-effect adjustment and reclassified $320 of unrealized gains on equity investments, net of tax, from accumulated other comprehensive loss to retained earnings on our consolidated balance sheet. Effective January 1, 2018, our results of operations include the changes in fair value of these financial instruments. |
Recent Accounting Guidance Not Yet Adopted | Recent Accounting Guidance Not Yet Adopted: In August 2018, the FASB issued Accounting Standards Update No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract , or ASU 2018-15. The amendments in ASU 2018-15 require implementation costs incurred by customers in cloud computing arrangements to be deferred and recognized over the term of the arrangement, if those costs would be capitalized by the customer in a software licensing arrangement under the internal-use software guidance. The amendments also require an entity to disclose the nature of its hosting arrangements and adhere to certain presentation requirements in its balance sheet, income statement and statement of cash flows. ASU 2018-15 is effective for our interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. The guidance can be applied either prospectively to all implementation costs incurred after the date of adoption or retrospectively. We are currently evaluating the effects the adoption of ASU 2018-15 will have on our consolidated financial position, results of operations and cash flows. In August 2018, the FASB issued Accounting Standards Update No. 2018-14, Compensation—Retirement Benefits - Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans , or ASU 2018-14. The amendments in ASU 2018-14 eliminate, add, and modify certain disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The amendments are effective for our annual reporting periods beginning after December 15, 2020, with early adoption permitted. The guidance is to be applied on a retrospective basis to all periods presented. We are currently evaluating the effects the adoption of ASU 2018-14 will have on our disclosures. In August 2018, the FASB issued Accounting Standards Update No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, or ASU 2018-13. The amendments in ASU 2018-13 eliminate, add, and modify certain disclosure requirements for fair value measurements. The amendments are effective for our interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted for either the entire ASU or only the provisions that eliminate or modify requirements. The amendments with respect to changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty are to be applied prospectively. All other amendments are to be applied retrospectively to all periods presented. We are currently evaluating the effects the adoption of ASU 2018-13 will have on our disclosures. In August 2018, the FASB issued Accounting Standards Update No. 2018-12, Financial Services—Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts, or ASU 2018-12. The amendments in ASU 2018-12 make changes to a variety of areas to simplify or improve the existing recognition, measurement, presentation and disclosure requirements for long-duration contracts issued by an insurance entity. The amendments require insurers to annually review the assumptions they make about their policyholders and update the liabilities for future policy benefits if the assumptions change. The amendments also simplify the amortization of deferred contract acquisition costs and add new disclosure requirements about the assumptions insurers use to measure their liabilities and how they may affect future cash flows. The amendments in ASU 2018-12 will be effective for our interim and annual reporting periods beginning after December 15, 2020. The amendments related to the liability for future policy benefits for traditional and limited-payment contracts and deferred acquisition costs are to be applied to contracts in force as of the beginning of the earliest period presented, with an option to apply such amendments retrospectively with a cumulative-effect adjustment to the opening balance of retained earnings as of the earliest period presented. The amendments for market risk benefits are to be applied retrospectively. We are currently evaluating the effects the adoption of ASU 2018-12 will have on our consolidated financial position, results of operations, cash flows, and related disclosures. In July 2018, the FASB issued Accounting Standards Update No. 2018-11, Leases (Topic 842): Targeted Improvements , or ASU 2018-11, and Accounting Standards Update No. 2018-10, Codification Improvements to Topic 842, Leases , or ASU 2018-10. The amendments in ASU 2018-11 provide for an additional and optional transition method that allows an entity to initially apply ASC Topic 842 at the adoption date and recognize a cumulative effect adjustment to its opening balance of retained earnings in the period of adoption and continue its reporting for the comparative periods presented in accordance with the current lease guidance, ASC Topic 840. The amendments in ASU 2018-11 also provide lessors with a practical expedient, by class of underlying asset, to not separate nonlease components from the associated lease component and, instead, to account for those components as a single component if the nonlease components otherwise would be accounted for under the new revenue guidance, ASC Topic 606 and if certain conditions are met. The amendments in ASU 2018-10 provide additional clarification and implementation guidance on certain aspects of the previously issued Accounting Standards Update No. 2016-02, Leases (Topic 842), or ASU 2016-02, and have the same effective and transition requirements as ASU 2016-02. Upon the effective date, ASU 2016-02 will supersede the current lease guidance in ASC Topic 840. Under the new guidance, lessees will be required to recognize for all leases, with the exception of short-term leases, a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis. Concurrently, lessees will be required to recognize a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASU 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. ASU 2016-02 requires a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative periods presented in the financial statements. As noted above, ASU 2018-11 provides for an additional and optional transition method. We plan to apply the optional transition method at the adoption date and are currently evaluating the effects the adoption of ASU 2016-02 will have on our consolidated financial statements, results of operations and cash flows. In July 2018, the FASB issued Accounting Standards Update No. 2018-09, Codification Improvements, or ASU 2018-09. This amendment makes changes to a variety of topics to clarify, correct errors in, or make minor improvements to the Accounting Standards Codification. The majority of the amendments in ASU 2018-09 will be effective for us in annual periods beginning after December 15, 2018. We are currently evaluating the effects the adoption of ASU 2018-09 will have on our consolidated financial statements, results of operations and cash flows. There were no other new accounting pronouncements that were issued or became effective since the issuance of our 2017 Annual Report on Form 10-K that had, or are expected to have, a material impact on our consolidated financial position, results of operations or cash flows. |
