Accounting Policies [Abstract]
Accounting Policies	NOTE 1 — ACCOUNTING POLICIES Reporting Entity HCA Holdings, Inc. is a holding company whose affiliates own and operate hospitals and related health care entities. The term “affiliates” includes direct and indirect subsidiaries of HCA Holdings, Inc. and partnerships and joint ventures in which such subsidiaries are partners. At December 31, 2016, these affiliates owned and operated 170 hospitals, 118 freestanding surgery centers and provided extensive outpatient and ancillary services. HCA Holdings, Inc.’s facilities are located in 20 states and England. The terms “Company,” “HCA,” “we,” “our” or “us,” as used herein and unless otherwise stated or indicated by context, refer to HCA Holdings, Inc. and its affiliates. The terms “facilities” or “hospitals” refer to entities owned and operated by affiliates of HCA and the term “employees” refers to employees of affiliates of HCA. Basis of Presentation The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. The consolidated financial statements include all subsidiaries and entities controlled by HCA. We generally define “control” as ownership of a majority of the voting interest of an entity. The consolidated financial statements include entities in which we absorb a majority of the entity’s expected losses, receive a majority of the entity’s expected residual returns, or both, as a result of ownership, contractual or other financial interests in the entity. The accounts of acquired entities are included in our consolidated financial statements for periods subsequent to our acquisition of controlling interests. Significant intercompany transactions have been eliminated. Investments in entities we do not control, but in which we have a substantial ownership interest and can exercise significant influence, are accounted for using the equity method. The majority of our expenses are “cost of revenue” items. Costs that could be classified as general and administrative include our corporate office costs, which were $373 million, $327 million and $285 million for the years ended December 31, 2016, 2015 and 2014, respectively. Revenues Revenues consist primarily of net patient service revenues that are recorded based upon established billing rates less allowances for contractual adjustments. Revenues are recorded during the period the health care services are provided, based upon the estimated amounts due from the patients and third-party payers. Third-party payers include federal and state agencies (under the Medicare and Medicaid programs), managed care health plans and commercial insurance companies (includes plans offered through the health insurance exchanges), and employers. Estimates of contractual allowances under managed care health plans are based upon the payment terms specified in the related contractual agreements. Contractual payment terms in managed care agreements are generally based upon predetermined rates per diagnosis, per diem rates or discounted fee-for-service Years Ended December 31, 2016 Ratio 2015 Ratio 2014 Ratio Medicare $ 8,895 21.4 % $ 8,654 21.8 % $ 8,354 22.6 % Managed Medicare 4,355 10.5 4,133 10.4 3,614 9.8 Medicaid 1,597 3.8 1,705 4.3 1,848 5.0 Managed Medicaid 2,478 6.0 2,234 5.6 1,923 5.2 Managed care and other insurers 23,441 56.5 21,882 55.2 20,066 54.4 International (managed care and other insurers) 1,195 2.9 1,295 3.3 1,311 3.6 41,961 101.1 39,903 100.6 37,116 100.6 Uninsured 1,135 2.7 1,927 4.9 1,494 4.0 Other 1,651 4.0 1,761 4.4 1,477 4.0 Revenues before provision for doubtful accounts 44,747 107.8 43,591 109.9 40,087 108.6 Provision for doubtful accounts (3,257 ) (7.8 ) (3,913 ) (9.9 ) (3,169 ) (8.6 ) Revenues $ 41,490 100.0 % $ 39,678 100.0 % $ 36,918 100.0 % Laws and regulations governing the Medicare and Medicaid programs are complex and subject to interpretation. As a result, there is at least a reasonable possibility recorded estimates will change by a material amount. Estimated reimbursement amounts are adjusted in subsequent periods as cost reports are prepared and filed and as final settlements are determined (in relation to certain government programs, primarily Medicare, this is generally referred to as the “cost report” filing and settlement process). The adjustments to estimated Medicare and Medicaid reimbursement amounts and disproportionate-share funds related primarily to cost reports filed during the respective year resulted in net increases to revenues of $31 million, $48 million and $50 million in 2016, 2015 and 2014, respectively. The adjustments to estimated reimbursement amounts related primarily to cost reports filed during previous years resulted in net increases to revenues of $90 million, $85 million and $53 million in 2016, 2015 and 2014, respectively. The Emergency Medical Treatment and Labor Act (“EMTALA”) requires any hospital participating in the Medicare program to conduct an appropriate medical screening examination of every person who presents to the hospital’s emergency room for treatment and, if the individual is suffering from an emergency medical condition, to either stabilize the condition or make an appropriate transfer of the individual to a facility able to handle the condition. The obligation to screen and stabilize emergency medical conditions exists regardless of an individual’s ability to pay for treatment. Federal and state laws and regulations require, and our commitment to providing quality patient care encourages, us to provide services to patients who are financially unable to pay for the health care services they receive. Patients treated at hospitals for nonelective care, who have income at or below 200% of the federal poverty level, are eligible for charity care. The federal poverty level is established by the federal government and is based on income and family size. Because we do not pursue collection of amounts determined to qualify as charity care, they are not reported in revenues. We provide discounts to uninsured patients who do not qualify for Medicaid or charity care. In implementing the uninsured discount policy, we may first attempt to provide assistance to uninsured patients to help determine whether they may qualify for Medicaid, other federal or state assistance or charity care. If an uninsured patient does not qualify for these programs, the uninsured discount is applied. To quantify the total impact of and trends related to uninsured accounts, we believe it is beneficial to view charity care, uninsured discounts and the provision for doubtful accounts in combination, rather than each separately. A summary of these amounts for the years ended December 31, follows (dollars in millions): 2016 Ratio 2015 Ratio 2014 Ratio Charity care $ 4,151 20 % $ 3,682 20 % $ 3,775 24 % Uninsured discounts 13,047 64 10,692 59 8,999 56 Provision for doubtful accounts 3,257 16 3,913 21 3,169 20 Total uncompensated care $ 20,455 100 % $ 18,287 100 % $ 15,943 100 % A summary of the estimated cost of total uncompensated care for the years ended December 31, follows (dollars in millions): 2016 2015 2014 Patient care costs (salaries and benefits, supplies, other operating expenses and depreciation and amortization) $ 35,304 $ 33,760 $ 31,478 Cost-to-charges 13.5 % 14.5 % 15.5 % Total uncompensated care $ 20,455 $ 18,287 $ 15,943 Multiply by the cost-to-charges 13.5 % 14.5 % 15.5 % Estimated cost of total uncompensated care $ 2,761 $ 2,652 $ 2,471 The sum of charity care, uninsured discounts and the provision for doubtful accounts, as a percentage of the sum of revenues, charity care, uninsured discounts and the provision for doubtful accounts was 33.0% for 2016, 31.5% for 2015 and 30.2% for 2014. Recent Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) and the International Accounting Standards Board issued a final, converged, principles-based standard on revenue recognition. Companies across all industries will use a five-step model to recognize revenue from customer contracts. The new standard, which replaces nearly all existing revenue recognition guidance, will require significant management judgments and change the way many companies recognize revenue in their financial statements. In July 2015, the FASB decided to defer the effective date of the new revenue standard by one year to annual and interim periods beginning after December 15, 2017 for public entities and permit entities to adopt one year earlier if they choose. The FASB decided, based on its outreach to various stakeholders and continuing amendments to the new revenue standard, that a deferral was necessary to provide adequate time to effectively implement the new standard. We are continuing to evaluate the effects the adoption of this standard will have on our financial statements and financial disclosures. We believe the most significant impact will be to the presentation of our income statement where the provision for doubtful accounts will be recorded as a direct reduction to revenues and will not be presented as a separate line item. We expect to adopt the new standard using the full retrospective application, and we do not believe the adoption will have a significant impact on our recognition of net revenues for any period. In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases 2016-02”), 2016-02 2016-02’s 2016-02 right-of-use In March 2016, the FASB issued Accounting Standards Update 2016-05, Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships 2016-05”), 2016-05 In March 2016, the FASB issued Accounting Standards Update 2016-09, Improvements to Employee Share-Based Payment Accounting 2016-09”), 2016-09 In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). 2017-04 2017-04 2017-04 Cash and Cash Equivalents Cash and cash equivalents include highly liquid investments with a maturity of three months or less when purchased. Our insurance subsidiaries’ cash equivalent investments in excess of the amounts required to pay estimated professional liability claims during the next twelve months are not included in cash and cash equivalents as these funds are not available for general corporate purposes. Carrying values of cash and cash equivalents approximate fair value due to the short-term nature of these instruments. Our cash management system provides for daily investment of available balances and the funding of outstanding checks when presented for payment. Outstanding, but unpresented, checks totaling $565 million and $517 million at December 31, 2016 and 2015, respectively, have been included in “accounts payable” in the consolidated balance sheets. Upon presentation for payment, these checks are funded through available cash balances or our credit facility. Accounts Receivable We receive payments for services rendered from federal and state agencies (under the Medicare and Medicaid programs), managed care health plans, commercial insurance companies, employers and patients. We recognize that revenues and receivables from government agencies are significant to our operations, but do not believe there are significant credit risks associated with these government agencies. We do not believe there are any other significant concentrations of revenues from any particular payer that would subject us to any significant credit risks in the collection of our accounts receivable. Additions to the allowance for doubtful accounts are made by means of the provision for doubtful accounts. Accounts written off as uncollectible are deducted from the allowance for doubtful accounts and subsequent recoveries are added. The amount of the provision for doubtful accounts is based upon management’s assessment of historical and expected net collections, business and economic conditions, trends in federal, state and private employer health care coverage and other collection indicators. The provision for doubtful accounts and the allowance for doubtful accounts relate to “uninsured” amounts due directly from patients (including copayment and deductible amounts from patients who have health care coverage). Accounts are written off when all reasonable internal and external collection efforts have been performed. We consider the return of an account from the secondary collection agency to be the culmination of our reasonable collection efforts and the timing basis for writing off the account balance. Writeoffs are based upon specific identification and the writeoff process requires a writeoff adjustment entry to the patient accounting system. Management relies on the results of detailed reviews of historical writeoffs and recoveries at facilities that represent a majority of our revenues and accounts receivable (the “hindsight analysis”) as a primary source of information to utilize in estimating the collectibility of our accounts receivable. We perform the hindsight analysis quarterly, utilizing rolling twelve-months accounts receivable collection and writeoff data. At December 31, 2016 and 2015, the allowance for doubtful accounts represented approximately 97.5% and 94.5%, respectively, of the $5.116 billion and $5.636 billion, respectively, patient due accounts receivable balance. The patient due accounts receivable balance represents the estimated uninsured portion of our accounts receivable. The estimated uninsured portion of Medicaid pending and uninsured discount pending accounts is included in our patient due accounts receivable balance. Days revenues in accounts receivable were 50 days, 53 days and 54 days at December 31, 2016, 2015 and 2014, respectively. Changes in general economic conditions, patient accounting service center operations, payer mix, or federal or state governmental health care coverage could affect our collection of accounts receivable, cash flows and results of operations. Inventories Inventories are stated at the lower of cost (first-in, first-out) Property and Equipment Depreciation expense, computed using the straight-line method, was $1.946 billion in 2016, $1.880 billion in 2015 and $1.798 billion in 2014. Buildings and improvements are depreciated over estimated useful lives ranging generally from 10 to 40 years. Estimated useful lives of equipment vary generally from four to 10 years. When events, circumstances or operating results indicate the carrying values of certain long-lived assets expected to be held and used might be impaired, we prepare projections of the undiscounted future cash flows expected to result from the use of the assets and their eventual disposition. If the projections indicate the recorded amounts are not expected to be recoverable, such amounts are reduced to estimated fair value. Fair value may be estimated based upon internal evaluations that include quantitative analyses of revenues and cash flows, reviews of recent sales of similar facilities and independent appraisals. Long-lived assets to be disposed of are reported at the lower of their carrying amounts or fair value less costs to sell or close. The estimates of fair value are usually based upon recent sales of similar assets and market responses based upon discussions with and offers received from potential buyers. Investments of Insurance Subsidiaries At December 31, 2016 and 2015, the investments of our 100% owned insurance subsidiaries were classified as “available-for-sale” Investments — Debt and Equity Securities Goodwill and Intangible Assets Goodwill is not amortized but is subject to annual impairment tests. In addition to the annual impairment review, impairment reviews are performed whenever circumstances indicate a possible impairment may exist. Impairment testing for goodwill is done at the reporting unit level. Reporting units are one level below the business segment level, and our impairment testing is performed at the operating division level. We compare the fair value of the reporting unit assets to the carrying amount, on at least an annual basis, to determine if there is potential impairment. If the fair value of the reporting unit assets is less than their carrying value, we compare the fair value of the goodwill to its carrying value. If the fair value of the goodwill is less than its carrying value, an impairment loss is recognized. Fair value is estimated based upon internal evaluations of each reporting unit that include quantitative analyses of market multiples, revenues and cash flows and reviews of recent sales of similar facilities. No goodwill impairments were recognized during 2016, 2015 and 2014. Since January 1, 2000, we have recognized total goodwill impairments of $102 million in the aggregate. None of the goodwill impairments related to evaluations of goodwill at the reporting unit level, as all recognized goodwill impairments during this period related to goodwill allocated to asset disposal groups. During 2016, goodwill increased by $41 million related to acquisitions and declined by $49 million related to sales, foreign currency translation and other adjustments. During 2015, goodwill increased by $323 million related to acquisitions and declined by $2 million related to foreign currency translation and other adjustments. During 2016, identifiable intangible assets declined by $19 million due to amortization, foreign currency translation and other adjustments. During 2015, identifiable intangible assets increased by $22 million related to acquisitions and declined by $22 million due to amortization, foreign currency translation and other adjustments. Identifiable intangible assets are amortized over estimated lives ranging generally from three to 10 years. The gross carrying amount of identifiable intangible assets at both December 31, 2016 and 2015 was $184 million and accumulated amortization was $79 million and $60 million, respectively. The gross carrying amount of indefinite-lived identifiable intangible assets at both December 31, 2016 and 2015 was $269 million. Indefinite-lived identifiable intangible assets are not amortized but are subject to annual impairment tests, and impairment reviews are performed whenever circumstances indicate a possible impairment may exist. Debt Issuance Costs Debt issuance costs are amortized based upon the terms of the respective debt obligations. The gross carrying amount of debt issuance costs at December 31, 2016 and 2015 was $334 million and $318 million, respectively, and accumulated amortization was $164 million and $151 million, respectively. Amortization of debt issuance costs is included in interest expense and was $34 million, $35 million and $42 million for 2016, 2015 and 2014, respectively. Professional Liability Claims Reserves for professional liability risks were $1.539 billion and $1.465 billion at December 31, 2016 and 2015, respectively. The current portion of the reserves, $391 million and $350 million at December 31, 2016 and 2015, respectively, is included in “other accrued expenses” in the consolidated balance sheets. Provisions for losses related to professional liability risks were $430 million, $344 million and $395 million for 2016, 2015 and 2014, respectively, and are included in “other operating expenses” in our consolidated income statements. Provisions for losses related to professional liability risks are based upon actuarially determined estimates. Loss and loss expense reserves represent the estimated ultimate net cost of all reported and unreported losses incurred through the respective consolidated balance sheet dates. The reserves for unpaid losses and loss expenses are estimated using individual case-basis valuations and actuarial analyses. Those estimates are subject to the effects of trends in loss severity and frequency. The estimates are continually reviewed and adjustments are recorded as experience develops or new information becomes known. Adjustments to the estimated reserve amounts are included in current operating results. The reserves for professional liability risks cover approximately 2,700 individual claims at both December 31, 2016 and 2015 and estimates for unreported potential claims. The time period required to resolve these claims can vary depending upon the jurisdiction and whether the claim is settled or litigated. During 2016 and 2015, $357 million and $305 million, respectively, of net payments were made for professional and general liability claims. The estimation of the timing of payments beyond a year can vary significantly. Although considerable variability is inherent in professional liability reserve estimates, we believe the reserves for losses and loss expenses are adequate; however, there can be no assurance the ultimate liability will not exceed our estimates. A portion of our professional liability risks is insured through a 100% owned insurance subsidiary. Subject to a $15 million per occurrence self-insured retention, our facilities are insured by our 100% owned insurance subsidiary for losses up to $50 million per occurrence. The insurance subsidiary has obtained reinsurance for professional liability risks generally above a retention level of $25 million per occurrence. We also maintain professional liability insurance with unrelated commercial carriers for losses in excess of amounts insured by our insurance subsidiary. The obligations covered by reinsurance and excess insurance contracts are included in the reserves for professional liability risks, as we remain liable to the extent the reinsurers and excess insurance carriers do not meet their obligations under the reinsurance and excess insurance contracts. The amounts receivable under the reinsurance contracts include $36 million and $35 million at December 31, 2016 and 2015, respectively, recorded in “other assets,” and $9 million at both December 31, 2016 and 2015 recorded in “other current assets.” Financial Instruments Derivative financial instruments are employed to manage interest rate risks, and are not used for trading or speculative purposes. We recognize our interest rate swap derivative instruments in the consolidated balance sheets at fair value. Changes in the fair value of derivatives are recognized periodically in stockholders’ equity, as a component of other comprehensive income (loss), provided the derivative financial instrument qualifies for hedge accounting. Gains and losses on derivatives designated as cash flow hedges, to the extent they are effective, are recorded in other comprehensive income (loss), and subsequently reclassified to earnings to offset the impact of the forecasted transactions when they occur. In the event the forecasted transaction to which a cash flow hedge relates is no longer likely, the amount in other comprehensive income (loss) is recognized in earnings and generally the derivative is terminated. The net interest paid or received on interest rate swaps is recognized as interest expense. Gains and losses resulting from the early termination of interest rate swap agreements are deferred and amortized as adjustments to interest expense over the remaining term of the debt originally associated with the terminated swap. Electronic Health Record Incentive Payments The American Recovery and Reinvestment Act of 2009 provides for Medicare and Medicaid incentive payments for eligible hospitals and professionals that adopt and meaningfully use certified electronic health record (“EHR”) technology. We recognize income related to Medicare and Medicaid incentive payments using a gain contingency model that is based upon when our eligible hospitals have demonstrated meaningful use of certified EHR technology for the applicable period and the cost report information for the full cost report year that will determine the final calculation of the incentive payment is available. We recognized $12 million, $47 million and $125 million of electronic health record incentive income during the years ended December 31, 2016, 2015 and 2014, respectively. Noncontrolling Interests in Consolidated Entities The consolidated financial statements include all assets, liabilities, revenues and expenses of less than 100% owned entities that we control. Accordingly, we have recorded noncontrolling interests in the earnings and equity of such entities. Reclassifications Certain prior year amounts have been reclassified to conform to the 2016 presentation.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation	NOTE 2 — SHARE-BASED COMPENSATION Stock Incentive Plan The 2006 Stock Incentive Plan for Key Employees of HCA Holdings, Inc. and its Affiliates, as Amended and Restated (the “Stock Incentive Plan”), is designed to promote the long term financial interests and growth of the Company by attracting and retaining management and other personnel and to motivate them to achieve long range goals and further the alignment of interests of participants with those of our stockholders through opportunities for increased stock, or stock-based, ownership in the Company. Portions of the options, stock appreciation rights (“SARs”) and restricted share units (“RSUs”) granted under the Stock Incentive Plan vest solely based upon continued employment over a specific period of time, and portions of the options, SARs and RSUs, and all performance share units (“PSUs”) vest based both upon continued employment over a specific period of time and upon the achievement of predetermined financial targets over time. We granted 1,601,300 and 1,746,300 SARs and 2,628,500 and 3,105,000 RSUs and PSUs under the Stock Incentive Plan during 2016 and 2015, respectively. At December 31, 2016, there were 11,957,900 stock options and SARs outstanding and exercisable, and there were 25,007,100 shares available for future grants under the Stock Incentive Plan. Employee Stock Purchase Plan The HCA Holdings, Inc. Employee Stock Purchase Plan (“ESPP”) was approved by the stockholders of the Company during the April 2014 Annual Meeting with 12,000,000 shares of our common stock reserved for issuance thereunder. The ESPP provides our participating employees an opportunity to obtain shares of our common stock at a discount (through payroll deductions over three-month periods). At December 31, 2016, 9,720,000 shares of common stock were reserved for issuance under the ESPP provisions. During 2016 and 2015, the Company recognized $8 million of compensation expense for each year related to the ESPP. Stock Option, SAR, RSU and PSU Activity The fair value of each stock option and SAR award is estimated on the grant date, using valuation models and the weighted average assumptions indicated in the following table. Awards under the Stock Incentive Plan generally vest based on continued employment (“Time Stock Options and SARs” and “Time RSUs”) and based upon continued employment and the achievement of certain financial targets (“Performance Stock Options and SARs”, “Performance RSUs” and “PSUs”). PSUs have a three-year cumulative earnings per share target, and the number of PSUs earned can vary from zero (for actual performance of less than 80% of target) to two times the original PSU grant (for actual performance of 120% or more of target). Each grant is valued as a single award with an expected term equal to the average expected term of the component vesting tranches. We use historical exercise behavior data and other factors to estimate the expected term of the options and SARs. The expected term of the share-based award is limited by the contractual term, and employee post-vesting termination behavior is incorporated in the historical exercise behavior data. Compensation cost is recognized on the straight-line attribution method. The straight-line attribution method requires that total compensation expense recognized must at least equal the vested portion of the grant-date fair value. The expected volatility is derived using historical stock price information for our common stock and that of certain peer group companies, and the volatility implied by the trading of options to purchase our stock on open-market exchanges. The risk-free interest rate is the approximate yield on United States Treasury Strips having a life equal to the expected share-based award life on the date of grant. The expected life is an estimate of the number of years a share-based award will be held before it is exercised. 2016 2015 2014 Risk-free interest rate 1.70 % 1.59 % 1.96 % Expected volatility 36 % 36 % 37 % Expected life, in years 6.25 6.25 6.25 Expected dividend yield — — — Information regarding Time Stock Options and SARs and Performance Stock Options and SARs activity during 2016, 2015 and 2014 is summarized below (share amounts in thousands): Time Performance Total Weighted Weighted Aggregate Options and SARs outstanding, December 31, 2013 16,809 18,377 35,186 $ 15.82 Granted 1,723 1,722 3,445 48.56 Exercised (3,322 ) (5,234 ) (8,556 ) 9.15 Cancelled (159 ) (121 ) (280 ) 29.54 Options and SARs outstanding, December 31, 2014 15,051 14,744 29,795 21.39 Granted 1,746 — 1,746 69.16 Exercised (4,093 ) (3,988 ) (8,081 ) 12.77 Cancelled (539 ) (329 ) (868 ) 32.59 Options and SARs outstanding, December 31, 2015 12,165 10,427 22,592 27.73 Granted 1,601 — 1,601 69.96 Exercised (2,521 ) (4,171 ) (6,692 ) 15.85 Cancelled (309 ) (126 ) (435 ) 55.17 Options and SARs outstanding, December 31, 2016 10,936 6,130 17,066 35.65 5.5 years $ 655 Options and SARs exercisable, December 31, 2016 7,015 4,943 11,958 $ 26.15 4.5 years $ 573 The weighted average fair values of stock options and SARs granted during 2016, 2015 and 2014 were $26.60, $26.10 and $19.13 per share, respectively.

Acquisitions and Dispositions	NOTE 3 — ACQUISITIONS AND DISPOSITIONS During 2016, we paid $343 million to acquire three hospital facilities and $233 million to acquire nonhospital health care entities. During 2015, we paid $15 million to acquire a hospital and $336 million to acquire nonhospital health care entities. During 2014, we paid $161 million to acquire three hospitals and $605 million to acquire nonhospital health care entities. Purchase price amounts have been allocated to the related assets acquired and liabilities assumed based upon their respective fair values. The purchase price paid in excess of the fair value of identifiable net assets of these acquired entities aggregated $41 million, $323 million and $542 million in 2016, 2015 and 2014, respectively. The consolidated financial statements include the accounts and operations of the acquired entities subsequent to the respective acquisition dates. The pro forma effects of these acquired entities on our results of operations for periods prior to the respective acquisition dates were not significant. During 2016, we received proceeds of $26 million and recognized a net pretax gain of $23 million ($19 million after tax) related to sales of real estate and other investments. During 2015, we received proceeds of $73 million and recognized a net pretax loss of $5 million ($3 million after tax) related to the sale of a hospital facility and sales of real estate and other investments. During 2014, we received proceeds of $51 million and recognized a net pretax gain of $29 million ($18 million after tax) related to the sale of a hospital facility and sales of real estate and other investments.

We reduced our provision for income taxes for the year ended December 31, 2016 by $51 million, including interest (net of tax), as a result of this resolution. The provision for income taxes reflects $15 million of reductions in interest expense (net of tax) and $7 million and $6 million of interest expense (net of tax) related to taxing authority examinations for the years ended December 31, 2016, 2015 and 2014, respectively. Our foreign pretax income was $149 million, $178 million and $238 million for the years ended December 31, 2016, 2015 and 2014, respectively.

Unrecognized tax benefits of $137 million ($233 million as of December 31, 2015) would affect the effective rate, if recognized. Depending on the resolution of any federal, state and foreign tax disputes, the completion of examinations by federal, state or foreign taxing authorities, or the expiration of statutes of limitation for specific taxing jurisdictions, we believe it is reasonably possible that our liability for unrecognized tax benefits may significantly increase or decrease within the next 12 months. However, we are currently unable to estimate the range of any possible change.

Fair Value Disclosures [Abstract]
Assets and Liabilities Measured at Fair Value	NOTE 8 — ASSETS AND LIABILITIES MEASURED AT FAIR VALUE Accounting Standards Codification 820, Fair Value Measurements and Disclosures Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input significant to the fair value measurement in its entirety. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment. Cash Traded Investments Our cash traded investments are generally classified within Level 1 or Level 2 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. Certain types of cash traded instruments are classified within Level 3 of the fair value hierarchy because they trade infrequently and therefore have little or no price transparency. The valuation of these securities involves the consideration of market factors and management’s judgment. Derivative Financial Instruments We have entered into interest rate swap agreements to manage our exposure to fluctuations in interest rates. The valuation of these instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. We incorporate credit valuation adjustments to reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements of these instruments. Although we determined the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by us and our counterparties. We assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions, and at December 31, 2016 and 2015, we determined the credit valuation adjustments were not significant to the overall valuation of our derivatives. The following tables summarize our assets and liabilities measured at fair value on a recurring basis as of December 31, 2016 and 2015, aggregated by the level in the fair value hierarchy within which those measurements fall (dollars in millions): December 31, 2016 Fair Value Fair Value Measurements Using Quoted Prices in Significant Other Significant Assets: Investments of insurance subsidiaries: Debt securities: States and municipalities $ 353 $ — $ 347 $ 6 Money market funds 28 28 — — 381 28 347 6 Equity securities 4 4 — — Investments of insurance subsidiaries 385 32 347 6 Less amounts classified as current assets (49 ) (28 ) (21 ) — $ 336 $ 4 $ 326 $ 6 Interest rate swaps (Other) $ 31 $ — $ 31 $ — Liabilities: Interest rate swaps (Income taxes and other liabilities) $ 12 $ — $ 12 $ — December 31, 2015 Fair Value Fair Value Measurements Using Quoted Prices in Significant Other Significant Assets: Investments of insurance subsidiaries: Debt securities: States and municipalities $ 444 $ — $ 438 $ 6 Money market funds 34 34 — — 478 34 438 6 Equity securities 4 4 — — Investments of insurance subsidiaries 482 38 438 6 Less amounts classified as current assets (50 ) (34 ) (16 ) — $ 432 $ 4 $ 422 $ 6 Liabilities: Interest rate swaps (Income taxes and other liabilities) $ 110 $ — $ 110 $ — The estimated fair value of our long-term debt was $32.833 billion and $31.411 billion at December 31, 2016 and 2015, respectively, compared to carrying amounts, excluding net debt issuance costs, aggregating $31.546 billion and $30.655 billion, respectively. The estimates of fair value are generally based upon the quoted market prices or quoted market prices for similar issues of long-term debt with the same maturities.

The applicable margin for borrowings under the senior secured credit facilities may be reduced subject to attaining certain leverage ratios. The senior secured credit facilities contain a number of covenants that restrict, subject to certain exceptions, our (and some or all of our subsidiaries’) ability to incur additional indebtedness, repay subordinated indebtedness, create liens on assets, sell assets, make investments, loans or advances, engage in certain transactions with affiliates, pay dividends and distributions, and enter into sale and leaseback transactions. In addition, we are required to satisfy and maintain a maximum total leverage ratio covenant under the cash flow credit facility and, in certain situations under the ABL credit facility, a minimum interest coverage ratio covenant. Senior secured notes consists of (i) $3.000 billion aggregate principal amount of 6.50% first lien notes due 2020; (ii) $1.350 billion aggregate principal amount of 5.875% first lien notes due 2022; (iii) $1.250 billion aggregate principal amount of 4.75% first lien notes due 2023; (iv) $1.500 billion aggregate principal amount of 3.75% first lien notes due 2019; (v) $2.000 billion aggregate principal amount of 5.00% first lien notes due 2024; (vi) $600 million aggregate principal amount of 4.25% first lien notes due 2019; (vii) $1.400 billion aggregate principal amount of 5.25% first lien notes due 2025; (viii) $1.500 billion aggregate principal amount of 5.25% first lien notes due 2026; and (ix) $1.200 billion aggregate principal amount of 4.50% first lien notes due 2027. Capital leases and other secured debt totaled $593 million at December 31, 2016. We use interest rate swap agreements to manage the variable rate exposure of our debt portfolio. At December 31, 2016, we had entered into effective interest rate swap agreements, in a total notional amount of $3.000 billion, in order to hedge a portion of our exposure to variable rate interest payments associated with the senior secured credit facilities. The effect of the interest rate swaps is reflected in the effective interest rates for the senior secured credit facilities.

Commitments and Contingencies Disclosure [Abstract]
Contingencies and Legal Claim Costs	NOTE 10 — CONTINGENCIES AND LEGAL CLAIM COSTS We operate in a highly regulated and litigious industry. As a result, various lawsuits, claims and legal and regulatory proceedings have been and can be expected to be instituted or asserted against us. We are also subject to claims and suits arising in the ordinary course of business, including claims for personal injuries or wrongful restriction of, or interference with, physicians’ staff privileges. In certain of these actions the claimants may seek punitive damages against us which may not be covered by insurance. We are also subject to claims by various taxing authorities for additional taxes and related interest and penalties. The resolution of any such lawsuits, claims or legal and regulatory proceedings could have a material, adverse effect on our results of operations, financial position or liquidity. Government Investigations, Claims and Litigation Health care companies are subject to numerous investigations by various governmental agencies. Under the federal False Claims Act (“FCA”), private parties have the right to bring qui tam Health Midwest Litigation In October 2009, the Health Care Foundation of Greater Kansas City, a nonprofit health foundation, filed suit against HCA Inc. in the Circuit Court of Jackson County, Missouri and alleged that HCA did not fund the level of capital expenditures and uncompensated care agreed to in connection with HCA’s purchase of hospitals from Health Midwest in 2003. The central issue in the case was whether HCA’s construction of new hospitals counted towards its $450 million five-year capital commitment. In addition, the plaintiff alleged that HCA did not make its required capital expenditures in a timely fashion. On January 24, 2013, the court ruled in favor of the plaintiff and awarded at least $162 million. The court also ordered a court-supervised accounting of HCA’s capital expenditures, as well as of expenditures on charity and uncompensated care during the ten years following the purchase. The court also indicated it would award plaintiff attorneys fees, which the parties stipulated were approximately $12 million for the trial phase. HCA recorded $175 million of legal claim costs in the fourth quarter of 2012 related to this ruling, and consistent with the judge’s order, accrued interest on that sum at 9% per annum. On April 25, 2014, the parties stipulated to an additional $78 million shortfall relating to the capital expenditures issue. HCA recorded $78 million of legal claims costs in the first quarter of 2014 as a result of the stipulation, and accrued interest on that amount at 9% per annum. Pursuant to the terms of the stipulation, the parties preserved their respective rights to contest the judge’s underlying ruling, whether through motions in the trial court or on appeal. On February 9, 2015, the parties reached an agreement to settle the part of their dispute relating to charity and uncompensated care for $15 million. The foundation is required to use that amount, net of attorneys’ fees, for charitable activities in the Kansas City area. The parties also agreed on an additional amount for attorneys’ fees for the plaintiff for the accounting phase of the case. The parties filed post-trial motions, on which the court ruled on October 21, 2015. The court denied defendants’ motion to have the court change its rulings on liability and damages related to the capital expenditures issue. The court granted the plaintiff’s motion for an award of additional pre-judgment

Employee Benefit Plans	NOTE 13 — EMPLOYEE BENEFIT PLANS We maintain defined contribution benefit plans that are available to employees who meet certain minimum requirements. Certain of the plans require that we match specified percentages of participant contributions up to certain maximum levels (generally, 100% of the first 3% to 9%, depending upon years of vesting service, of compensation deferred by participants). The cost of these plans totaled $444 million for 2016, $432 million for 2015 and $404 million for 2014. Our contributions are funded periodically during each year. We maintain the noncontributory, nonqualified Restoration Plan to provide certain retirement benefits for eligible employees. Eligibility for the Restoration Plan is based upon earning eligible compensation in excess of the Social Security Wage Base and attaining 1,000 or more hours of service during the plan year. Company credits to participants’ account balances (the Restoration Plan is not funded) depend upon participants’ compensation, years of vesting service and certain IRS limitations related to the HCA 401(k) plan. Benefits expense under this plan was $20 million for 2016, $20 million for 2015 and $31 million for 2014. Accrued benefits liabilities under this plan totaled $175 million at December 31, 2016 and $164 million at December 31, 2015.

Benefits expense under the plan was $22 million for 2016, $33 million for 2015 and $31 million for 2014.

Segment Reporting [Abstract]
Segment and Geographic Information	NOTE 14 — SEGMENT AND GEOGRAPHIC INFORMATION We operate in one line of business, which is operating hospitals and related health care entities. We operate in two geographically organized groups: the National and American Groups. At December 31, 2016, the National Group included 84 hospitals located in Alaska, California, Florida, southern Georgia, Idaho, Indiana, northern Kentucky, Nevada, New Hampshire, South Carolina, Utah and Virginia, and the American Group included 80 hospitals located in Colorado, northern Georgia, Kansas, southern Kentucky, Louisiana, Mississippi, Missouri, Oklahoma, Tennessee and Texas. We also operate six hospitals in England, and these facilities are included in the Corporate and other group. Adjusted segment EBITDA is defined as income before depreciation and amortization, interest expense, losses (gains) on sales of facilities, losses on retirement of debt, legal claim costs (benefits), income taxes and net income attributable to noncontrolling interests. We use adjusted segment EBITDA as an analytical indicator for purposes of allocating resources to geographic areas and assessing their performance. Adjusted segment EBITDA is commonly used as an analytical indicator within the health care industry, and also serves as a measure of leverage capacity and debt service ability. Adjusted segment EBITDA should not be considered as a measure of financial performance under generally accepted accounting principles, and the items excluded from adjusted segment EBITDA are significant components in understanding and assessing financial performance. Because adjusted segment EBITDA is not a measurement determined in accordance with generally accepted accounting principles and is thus susceptible to varying calculations, adjusted segment EBITDA, as presented, may not be comparable to other similarly titled measures of other companies. The geographic distributions of our revenues, equity in earnings of affiliates, adjusted segment EBITDA, depreciation and amortization, assets and goodwill and other intangible assets are summarized in the following table (dollars in millions): For the Years Ended December 31, 2016 2015 2014 Revenues: National Group $ 19,845 $ 18,756 $ 17,335 American Group 19,648 18,872 17,532 Corporate and other 1,997 2,050 2,051 $ 41,490 $ 39,678 $ 36,918 Equity in earnings of affiliates: National Group $ (20 ) $ (7 ) $ (15 ) American Group (38 ) (32 ) (31 ) Corporate and other 4 (7 ) 3 $ (54 ) $ (46 ) $ (43 ) Adjusted segment EBITDA: National Group $ 4,565 $ 4,271 $ 3,848 American Group 4,177 4,207 4,025 Corporate and other (524 ) (563 ) (445 ) $ 8,218 $ 7,915 $ 7,428 Depreciation and amortization: National Group $ 806 $ 769 $ 749 American Group 905 886 840 Corporate and other 255 249 231 $ 1,966 $ 1,904 $ 1,820 For the Years Ended December 31, 2016 2015 2014 Adjusted segment EBITDA $ 8,218 $ 7,915 $ 7,428 Depreciation and amortization 1,966 1,904 1,820 Interest expense 1,707 1,665 1,743 Losses (gains) on sales of facilities (23 ) 5 (29 ) Losses on retirement of debt 4 135 335 Legal claim costs (benefits) (246 ) 249 78 Income before income taxes $ 4,810 $ 3,957 $ 3,481 December 31, 2016 2015 2014 Assets: National Group $ 12,320 $ 11,332 $ 10,590 American Group 16,199 15,240 15,091 Corporate and other 5,239 6,172 5,299 $ 33,758 $ 32,744 $ 30,980 National American Corporate Total Goodwill and other intangible assets: Balance at December 31, 2013 $ 1,104 $ 4,190 $ 609 $ 5,903 Acquisitions 72 428 48 548 Foreign currency translation, amortization and other (6 ) (4 ) (25 ) (35 ) Balance at December 31, 2014 1,170 4,614 632 6,416 Acquisitions 318 27 — 345 Foreign currency translation, amortization and other (7 ) (3 ) (20 ) (30 ) Balance at December 31, 2015 1,481 4,638 612 6,731 Acquisitions — 33 8 41 Sales, foreign currency translation, amortization and other (23 ) (10 ) (35 ) (68 ) Balance at December 31, 2016 $ 1,458 $ 4,661 $ 585 $ 6,704

Accounting Policies (Policies)

Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Basis of Presentation	Basis of Presentation The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. The consolidated financial statements include all subsidiaries and entities controlled by HCA. We generally define “control” as ownership of a majority of the voting interest of an entity. The consolidated financial statements include entities in which we absorb a majority of the entity’s expected losses, receive a majority of the entity’s expected residual returns, or both, as a result of ownership, contractual or other financial interests in the entity. The accounts of acquired entities are included in our consolidated financial statements for periods subsequent to our acquisition of controlling interests. Significant intercompany transactions have been eliminated. Investments in entities we do not control, but in which we have a substantial ownership interest and can exercise significant influence, are accounted for using the equity method. The majority of our expenses are “cost of revenue” items. Costs that could be classified as general and administrative include our corporate office costs, which were $373 million, $327 million and $285 million for the years ended December 31, 2016, 2015 and 2014, respectively.
Revenues	Revenues Revenues consist primarily of net patient service revenues that are recorded based upon established billing rates less allowances for contractual adjustments. Revenues are recorded during the period the health care services are provided, based upon the estimated amounts due from the patients and third-party payers. Third-party payers include federal and state agencies (under the Medicare and Medicaid programs), managed care health plans and commercial insurance companies (includes plans offered through the health insurance exchanges), and employers. Estimates of contractual allowances under managed care health plans are based upon the payment terms specified in the related contractual agreements. Contractual payment terms in managed care agreements are generally based upon predetermined rates per diagnosis, per diem rates or discounted fee-for-service Years Ended December 31, 2016 Ratio 2015 Ratio 2014 Ratio Medicare $ 8,895 21.4 % $ 8,654 21.8 % $ 8,354 22.6 % Managed Medicare 4,355 10.5 4,133 10.4 3,614 9.8 Medicaid 1,597 3.8 1,705 4.3 1,848 5.0 Managed Medicaid 2,478 6.0 2,234 5.6 1,923 5.2 Managed care and other insurers 23,441 56.5 21,882 55.2 20,066 54.4 International (managed care and other insurers) 1,195 2.9 1,295 3.3 1,311 3.6 41,961 101.1 39,903 100.6 37,116 100.6 Uninsured 1,135 2.7 1,927 4.9 1,494 4.0 Other 1,651 4.0 1,761 4.4 1,477 4.0 Revenues before provision for doubtful accounts 44,747 107.8 43,591 109.9 40,087 108.6 Provision for doubtful accounts (3,257 ) (7.8 ) (3,913 ) (9.9 ) (3,169 ) (8.6 ) Revenues $ 41,490 100.0 % $ 39,678 100.0 % $ 36,918 100.0 % Laws and regulations governing the Medicare and Medicaid programs are complex and subject to interpretation. As a result, there is at least a reasonable possibility recorded estimates will change by a material amount. Estimated reimbursement amounts are adjusted in subsequent periods as cost reports are prepared and filed and as final settlements are determined (in relation to certain government programs, primarily Medicare, this is generally referred to as the “cost report” filing and settlement process). The adjustments to estimated Medicare and Medicaid reimbursement amounts and disproportionate-share funds related primarily to cost reports filed during the respective year resulted in net increases to revenues of $31 million, $48 million and $50 million in 2016, 2015 and 2014, respectively. The adjustments to estimated reimbursement amounts related primarily to cost reports filed during previous years resulted in net increases to revenues of $90 million, $85 million and $53 million in 2016, 2015 and 2014, respectively. The Emergency Medical Treatment and Labor Act (“EMTALA”) requires any hospital participating in the Medicare program to conduct an appropriate medical screening examination of every person who presents to the hospital’s emergency room for treatment and, if the individual is suffering from an emergency medical condition, to either stabilize the condition or make an appropriate transfer of the individual to a facility able to handle the condition. The obligation to screen and stabilize emergency medical conditions exists regardless of an individual’s ability to pay for treatment. Federal and state laws and regulations require, and our commitment to providing quality patient care encourages, us to provide services to patients who are financially unable to pay for the health care services they receive. Patients treated at hospitals for nonelective care, who have income at or below 200% of the federal poverty level, are eligible for charity care. The federal poverty level is established by the federal government and is based on income and family size. Because we do not pursue collection of amounts determined to qualify as charity care, they are not reported in revenues. We provide discounts to uninsured patients who do not qualify for Medicaid or charity care. In implementing the uninsured discount policy, we may first attempt to provide assistance to uninsured patients to help determine whether they may qualify for Medicaid, other federal or state assistance or charity care. If an uninsured patient does not qualify for these programs, the uninsured discount is applied. To quantify the total impact of and trends related to uninsured accounts, we believe it is beneficial to view charity care, uninsured discounts and the provision for doubtful accounts in combination, rather than each separately. A summary of these amounts for the years ended December 31, follows (dollars in millions): 2016 Ratio 2015 Ratio 2014 Ratio Charity care $ 4,151 20 % $ 3,682 20 % $ 3,775 24 % Uninsured discounts 13,047 64 10,692 59 8,999 56 Provision for doubtful accounts 3,257 16 3,913 21 3,169 20 Total uncompensated care $ 20,455 100 % $ 18,287 100 % $ 15,943 100 % A summary of the estimated cost of total uncompensated care for the years ended December 31, follows (dollars in millions): 2016 2015 2014 Patient care costs (salaries and benefits, supplies, other operating expenses and depreciation and amortization) $ 35,304 $ 33,760 $ 31,478 Cost-to-charges 13.5 % 14.5 % 15.5 % Total uncompensated care $ 20,455 $ 18,287 $ 15,943 Multiply by the cost-to-charges 13.5 % 14.5 % 15.5 % Estimated cost of total uncompensated care $ 2,761 $ 2,652 $ 2,471 The sum of charity care, uninsured discounts and the provision for doubtful accounts, as a percentage of the sum of revenues, charity care, uninsured discounts and the provision for doubtful accounts was 33.0% for 2016, 31.5% for 2015 and 30.2% for 2014.
Recent Pronouncements	Recent Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) and the International Accounting Standards Board issued a final, converged, principles-based standard on revenue recognition. Companies across all industries will use a five-step model to recognize revenue from customer contracts. The new standard, which replaces nearly all existing revenue recognition guidance, will require significant management judgments and change the way many companies recognize revenue in their financial statements. In July 2015, the FASB decided to defer the effective date of the new revenue standard by one year to annual and interim periods beginning after December 15, 2017 for public entities and permit entities to adopt one year earlier if they choose. The FASB decided, based on its outreach to various stakeholders and continuing amendments to the new revenue standard, that a deferral was necessary to provide adequate time to effectively implement the new standard. We are continuing to evaluate the effects the adoption of this standard will have on our financial statements and financial disclosures. We believe the most significant impact will be to the presentation of our income statement where the provision for doubtful accounts will be recorded as a direct reduction to revenues and will not be presented as a separate line item. We expect to adopt the new standard using the full retrospective application, and we do not believe the adoption will have a significant impact on our recognition of net revenues for any period. In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases 2016-02”), 2016-02 2016-02’s 2016-02 right-of-use In March 2016, the FASB issued Accounting Standards Update 2016-05, Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships 2016-05”), 2016-05 In March 2016, the FASB issued Accounting Standards Update 2016-09, Improvements to Employee Share-Based Payment Accounting 2016-09”), 2016-09 In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). 2017-04 2017-04 2017-04
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include highly liquid investments with a maturity of three months or less when purchased. Our insurance subsidiaries’ cash equivalent investments in excess of the amounts required to pay estimated professional liability claims during the next twelve months are not included in cash and cash equivalents as these funds are not available for general corporate purposes. Carrying values of cash and cash equivalents approximate fair value due to the short-term nature of these instruments. Our cash management system provides for daily investment of available balances and the funding of outstanding checks when presented for payment. Outstanding, but unpresented, checks totaling $565 million and $517 million at December 31, 2016 and 2015, respectively, have been included in “accounts payable” in the consolidated balance sheets. Upon presentation for payment, these checks are funded through available cash balances or our credit facility.
Accounts Receivable	Accounts Receivable We receive payments for services rendered from federal and state agencies (under the Medicare and Medicaid programs), managed care health plans, commercial insurance companies, employers and patients. We recognize that revenues and receivables from government agencies are significant to our operations, but do not believe there are significant credit risks associated with these government agencies. We do not believe there are any other significant concentrations of revenues from any particular payer that would subject us to any significant credit risks in the collection of our accounts receivable. Additions to the allowance for doubtful accounts are made by means of the provision for doubtful accounts. Accounts written off as uncollectible are deducted from the allowance for doubtful accounts and subsequent recoveries are added. The amount of the provision for doubtful accounts is based upon management’s assessment of historical and expected net collections, business and economic conditions, trends in federal, state and private employer health care coverage and other collection indicators. The provision for doubtful accounts and the allowance for doubtful accounts relate to “uninsured” amounts due directly from patients (including copayment and deductible amounts from patients who have health care coverage). Accounts are written off when all reasonable internal and external collection efforts have been performed. We consider the return of an account from the secondary collection agency to be the culmination of our reasonable collection efforts and the timing basis for writing off the account balance. Writeoffs are based upon specific identification and the writeoff process requires a writeoff adjustment entry to the patient accounting system. Management relies on the results of detailed reviews of historical writeoffs and recoveries at facilities that represent a majority of our revenues and accounts receivable (the “hindsight analysis”) as a primary source of information to utilize in estimating the collectibility of our accounts receivable. We perform the hindsight analysis quarterly, utilizing rolling twelve-months accounts receivable collection and writeoff data. At December 31, 2016 and 2015, the allowance for doubtful accounts represented approximately 97.5% and 94.5%, respectively, of the $5.116 billion and $5.636 billion, respectively, patient due accounts receivable balance. The patient due accounts receivable balance represents the estimated uninsured portion of our accounts receivable. The estimated uninsured portion of Medicaid pending and uninsured discount pending accounts is included in our patient due accounts receivable balance. Days revenues in accounts receivable were 50 days, 53 days and 54 days at December 31, 2016, 2015 and 2014, respectively. Changes in general economic conditions, patient accounting service center operations, payer mix, or federal or state governmental health care coverage could affect our collection of accounts receivable, cash flows and results of operations.
Inventories	Inventories Inventories are stated at the lower of cost (first-in, first-out)
Property and Equipment	Property and Equipment Depreciation expense, computed using the straight-line method, was $1.946 billion in 2016, $1.880 billion in 2015 and $1.798 billion in 2014. Buildings and improvements are depreciated over estimated useful lives ranging generally from 10 to 40 years. Estimated useful lives of equipment vary generally from four to 10 years. When events, circumstances or operating results indicate the carrying values of certain long-lived assets expected to be held and used might be impaired, we prepare projections of the undiscounted future cash flows expected to result from the use of the assets and their eventual disposition. If the projections indicate the recorded amounts are not expected to be recoverable, such amounts are reduced to estimated fair value. Fair value may be estimated based upon internal evaluations that include quantitative analyses of revenues and cash flows, reviews of recent sales of similar facilities and independent appraisals. Long-lived assets to be disposed of are reported at the lower of their carrying amounts or fair value less costs to sell or close. The estimates of fair value are usually based upon recent sales of similar assets and market responses based upon discussions with and offers received from potential buyers.
Investments of Insurance Subsidiaries	Investments of Insurance Subsidiaries At December 31, 2016 and 2015, the investments of our 100% owned insurance subsidiaries were classified as “available-for-sale” Investments — Debt and Equity Securities
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill is not amortized but is subject to annual impairment tests. In addition to the annual impairment review, impairment reviews are performed whenever circumstances indicate a possible impairment may exist. Impairment testing for goodwill is done at the reporting unit level. Reporting units are one level below the business segment level, and our impairment testing is performed at the operating division level. We compare the fair value of the reporting unit assets to the carrying amount, on at least an annual basis, to determine if there is potential impairment. If the fair value of the reporting unit assets is less than their carrying value, we compare the fair value of the goodwill to its carrying value. If the fair value of the goodwill is less than its carrying value, an impairment loss is recognized. Fair value is estimated based upon internal evaluations of each reporting unit that include quantitative analyses of market multiples, revenues and cash flows and reviews of recent sales of similar facilities. No goodwill impairments were recognized during 2016, 2015 and 2014. Since January 1, 2000, we have recognized total goodwill impairments of $102 million in the aggregate. None of the goodwill impairments related to evaluations of goodwill at the reporting unit level, as all recognized goodwill impairments during this period related to goodwill allocated to asset disposal groups. During 2016, goodwill increased by $41 million related to acquisitions and declined by $49 million related to sales, foreign currency translation and other adjustments. During 2015, goodwill increased by $323 million related to acquisitions and declined by $2 million related to foreign currency translation and other adjustments. During 2016, identifiable intangible assets declined by $19 million due to amortization, foreign currency translation and other adjustments. During 2015, identifiable intangible assets increased by $22 million related to acquisitions and declined by $22 million due to amortization, foreign currency translation and other adjustments. Identifiable intangible assets are amortized over estimated lives ranging generally from three to 10 years. The gross carrying amount of identifiable intangible assets at both December 31, 2016 and 2015 was $184 million and accumulated amortization was $79 million and $60 million, respectively. The gross carrying amount of indefinite-lived identifiable intangible assets at both December 31, 2016 and 2015 was $269 million. Indefinite-lived identifiable intangible assets are not amortized but are subject to annual impairment tests, and impairment reviews are performed whenever circumstances indicate a possible impairment may exist.
Debt Issuance Costs	Debt Issuance Costs Debt issuance costs are amortized based upon the terms of the respective debt obligations. The gross carrying amount of debt issuance costs at December 31, 2016 and 2015 was $334 million and $318 million, respectively, and accumulated amortization was $164 million and $151 million, respectively. Amortization of debt issuance costs is included in interest expense and was $34 million, $35 million and $42 million for 2016, 2015 and 2014, respectively.
Professional Liability Claims	Professional Liability Claims Reserves for professional liability risks were $1.539 billion and $1.465 billion at December 31, 2016 and 2015, respectively. The current portion of the reserves, $391 million and $350 million at December 31, 2016 and 2015, respectively, is included in “other accrued expenses” in the consolidated balance sheets. Provisions for losses related to professional liability risks were $430 million, $344 million and $395 million for 2016, 2015 and 2014, respectively, and are included in “other operating expenses” in our consolidated income statements. Provisions for losses related to professional liability risks are based upon actuarially determined estimates. Loss and loss expense reserves represent the estimated ultimate net cost of all reported and unreported losses incurred through the respective consolidated balance sheet dates. The reserves for unpaid losses and loss expenses are estimated using individual case-basis valuations and actuarial analyses. Those estimates are subject to the effects of trends in loss severity and frequency. The estimates are continually reviewed and adjustments are recorded as experience develops or new information becomes known. Adjustments to the estimated reserve amounts are included in current operating results. The reserves for professional liability risks cover approximately 2,700 individual claims at both December 31, 2016 and 2015 and estimates for unreported potential claims. The time period required to resolve these claims can vary depending upon the jurisdiction and whether the claim is settled or litigated. During 2016 and 2015, $357 million and $305 million, respectively, of net payments were made for professional and general liability claims. The estimation of the timing of payments beyond a year can vary significantly. Although considerable variability is inherent in professional liability reserve estimates, we believe the reserves for losses and loss expenses are adequate; however, there can be no assurance the ultimate liability will not exceed our estimates. A portion of our professional liability risks is insured through a 100% owned insurance subsidiary. Subject to a $15 million per occurrence self-insured retention, our facilities are insured by our 100% owned insurance subsidiary for losses up to $50 million per occurrence. The insurance subsidiary has obtained reinsurance for professional liability risks generally above a retention level of $25 million per occurrence. We also maintain professional liability insurance with unrelated commercial carriers for losses in excess of amounts insured by our insurance subsidiary. The obligations covered by reinsurance and excess insurance contracts are included in the reserves for professional liability risks, as we remain liable to the extent the reinsurers and excess insurance carriers do not meet their obligations under the reinsurance and excess insurance contracts. The amounts receivable under the reinsurance contracts include $36 million and $35 million at December 31, 2016 and 2015, respectively, recorded in “other assets,” and $9 million at both December 31, 2016 and 2015 recorded in “other current assets.”
Financial Instruments	Financial Instruments Derivative financial instruments are employed to manage interest rate risks, and are not used for trading or speculative purposes. We recognize our interest rate swap derivative instruments in the consolidated balance sheets at fair value. Changes in the fair value of derivatives are recognized periodically in stockholders’ equity, as a component of other comprehensive income (loss), provided the derivative financial instrument qualifies for hedge accounting. Gains and losses on derivatives designated as cash flow hedges, to the extent they are effective, are recorded in other comprehensive income (loss), and subsequently reclassified to earnings to offset the impact of the forecasted transactions when they occur. In the event the forecasted transaction to which a cash flow hedge relates is no longer likely, the amount in other comprehensive income (loss) is recognized in earnings and generally the derivative is terminated. The net interest paid or received on interest rate swaps is recognized as interest expense. Gains and losses resulting from the early termination of interest rate swap agreements are deferred and amortized as adjustments to interest expense over the remaining term of the debt originally associated with the terminated swap.
Electronic Health Record Incentive Payments	Electronic Health Record Incentive Payments The American Recovery and Reinvestment Act of 2009 provides for Medicare and Medicaid incentive payments for eligible hospitals and professionals that adopt and meaningfully use certified electronic health record (“EHR”) technology. We recognize income related to Medicare and Medicaid incentive payments using a gain contingency model that is based upon when our eligible hospitals have demonstrated meaningful use of certified EHR technology for the applicable period and the cost report information for the full cost report year that will determine the final calculation of the incentive payment is available. We recognized $12 million, $47 million and $125 million of electronic health record incentive income during the years ended December 31, 2016, 2015 and 2014, respectively.
Noncontrolling Interests in Consolidated Entities	Noncontrolling Interests in Consolidated Entities The consolidated financial statements include all assets, liabilities, revenues and expenses of less than 100% owned entities that we control. Accordingly, we have recorded noncontrolling interests in the earnings and equity of such entities.
Reclassifications	Reclassifications Certain prior year amounts have been reclassified to conform to the 2016 presentation.
Earning Per Share	We compute basic earnings per share using the weighted average number of common shares outstanding. We compute diluted earnings per share using the weighted average number of common shares outstanding plus the dilutive effect of outstanding stock options, SARs, RSUs and PSUs, computed using the treasury stock method.
Fair Value Measurements and Disclosures	Accounting Standards Codification 820, Fair Value Measurements and Disclosures Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input significant to the fair value measurement in its entirety. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment.
Cash Traded Investments	Cash Traded Investments Our cash traded investments are generally classified within Level 1 or Level 2 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. Certain types of cash traded instruments are classified within Level 3 of the fair value hierarchy because they trade infrequently and therefore have little or no price transparency. The valuation of these securities involves the consideration of market factors and management’s judgment.
Derivative Financial Instruments	Derivative Financial Instruments We have entered into interest rate swap agreements to manage our exposure to fluctuations in interest rates. The valuation of these instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. We incorporate credit valuation adjustments to reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements of these instruments. Although we determined the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by us and our counterparties. We assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions, and at December 31, 2016 and 2015, we determined the credit valuation adjustments were not significant to the overall valuation of our derivatives.
Interest Rate Swaps [Member]
Financial Instruments	Interest Rate Swap Agreements We have entered into interest rate swap agreements to manage our exposure to fluctuations in interest rates. These swap agreements involve the exchange of fixed and variable rate interest payments between two parties based on common notional principal amounts and maturity dates. Pay-fixed
