Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization LHC Group, Inc. (the “Company”) is a health care provider specializing in the post-acute continuum of care. The Company provides home health services, hospice services, home and community-based services, facility-based services, the latter primarily through long-term acute care hospitals (“LTACHs”), and healthcare innovations services ("HCI"). On April 1, 2018 , the Company completed its previously announced "merger of equals" business combination (the "Merger") with Almost Family, Inc. ("Almost Family"). See Note 3 of the Notes to Condensed Consolidated Financial Statements. As of June 30, 2018 , the Company, through its wholly- and majority-owned subsidiaries, equity joint ventures, controlled affiliates, and management agreements (including, as a result of the Merger, those owned and operated by Almost Family), operated 777 service providers in 37 states within the continental United States. Unaudited Interim Financial Information The accompanying unaudited condensed consolidated balance sheets as of June 30, 2018 and December 31, 2017 , and the related unaudited condensed consolidated statements of income for the three and six months ended June 30, 2018 and 2017 , condensed consolidated statement of changes in equity for the six months ended June 30, 2018 , condensed consolidated statements of cash flows for the six months ended June 30, 2018 and 2017 , and related notes (collectively, these financial statements are referred to as the "interim financial statements" and together with the related notes are referred to herein as the “interim financial information”) have been prepared by the Company. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been included. Operating results for the three and six months ended June 30, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018 . Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted from the interim financial information presented. This report should be read in conjunction with the Company’s consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 . The report was filed with the Securities and Exchange Commission (the “SEC”) on March 1, 2018 , and includes information and disclosures not included herein. The accompanying unaudited condensed consolidated statements of income for the three and six months ended June 30, 2018 , include the results of operations for Almost Family for the period April 1, 2018 to June 30, 2018 . The accompanying unaudited condensed consolidated balance sheet at June 30, 2018 includes the preliminary valuation of the assets acquired and liabilities assumed in connection with the Merger. See Note 3 of the Notes to Condensed Consolidated Financial Statements.

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported revenue and expenses during the reporting period. Actual results could differ from those estimates. Critical Accounting Policies The Company’s most critical accounting policies relate to the principles of consolidation and revenue recognition. Principles of Consolidation The interim financial information includes all subsidiaries and entities controlled by the Company through direct ownership of majority interest or controlling member ownership of such entities (including, as a result of the Merger, those owned and operated by Almost Family). Third party equity interests in the consolidated joint ventures are reflected as noncontrolling interests in the Company’s interim financial information. See Note 9 of the Notes to Condensed Consolidated Financial Statements. The following table summarizes the percentage of net service revenue earned by type of ownership or relationship the Company had with the operating entity: Three Months Ended Six Months Ended Ownership type 2018 2017 2018 2017 Wholly-owned subsidiaries 59.5 % 53.3 % 55.5 % 53.5 % Equity joint ventures 39.4 45.1 43.0 44.8 Other 1.1 1.6 1.5 1.7 100.0 % 100.0 % 100.0 % 100.0 % All significant intercompany accounts and transactions have been eliminated in the Company’s accompanying interim financial information. Business combinations accounted for under the acquisition method have been included in the interim financial information from the respective dates of acquisition. The Company consolidates equity joint venture entities as the Company has controlling interests in the entities, has voting control over these entities, or has ability to exercise significant influence in the entities. The members of the Company's equity joint ventures participate in profits and losses in proportion to their equity interests. The Company also consolidates entities which have license leasing arrangements as the Company owns 100% of the equity of these subsidiaries. The Company has various management services agreements under which the Company manages certain operations of agencies. The Company does not consolidate these agencies if the Company does not have an ownership interest in, nor does it have an obligation to absorb losses of, or right to receive benefits from the entities that own the agencies. Revenue Recognition Basis of Presentation The Company adopted ASU No. 2014-09, Revenue from Contracts with Customers , ("ASU 2014-09") on January 1, 2018 on a full retrospective basis, which required the Company to present the prior comparable period as adjusted. The adoption of the standard did not have a material impact on the Company's interim financial statements. The Company did not adjust the opening balance of retained earnings to account for the implementation of the requirements of this standard as there are no timing differences related to the recognition of implicit price concessions as part of net service revenue. All amounts previously classified as provision for bad debts are now classified within the Company's net service revenue. For the three and six months ended June 30, 2018, the Company recorded $7.7 million and $12.6 million , respectively, of implicit price concessions as a direct reduction of net service revenue that would have been recorded as provision for bad debts prior to the adoption of ASU 2014-09. Adoption of the standard impacted the Company's previously reported results as follows (amounts in thousands): As previously reported Adjustment for ASU 2014-09 As adjusted As of December 31, 2017 Condensed Consolidated Balance Sheets Patient accounts receivable $ 161,898 $ — $ 161,898 Allowance for uncollectible accounts 23,556 (23,556 ) — Three Months Ended June 30, 2017 Condensed Consolidated Statements of Income: Net service revenue 260,210 (2,675 ) 257,535 Provision for bad debts 2,675 (2,675 ) — Net income attributable to LHC Group, Inc.'s common stockholders 11,304 — 11,304 Six Months Ended June 30, 2017 Condensed Consolidated Statements of Income: Net service revenue 506,828 (5,044 ) 501,784 Provision for bad debts 5,044 (5,044 ) — Net income attributable to LHC Group, Inc.'s common stockholders 20,771 — 20,771 Condensed Consolidated Statements of Cash Flows: Provision for bad debts 5,044 (5,044 ) — Changes in operating assets and liabilities, net of acquisitions: Receivables (6,970 ) 5,044 (1,926 ) Net service revenue is reported at the amount that reflects the consideration to which the Company expects to receive in exchange for providing services. These amounts are due from Medicare, Medicaid, Managed Care, Commercial, and others for services rendered, and they include implicit price concessions for retroactive revenue adjustments due to actual receipts from third-party payors, settlement of audits, and reviews. The estimated uncollectible amounts due from these payors are considered implicit price concessions that are a direct reduction to net service revenue. The Company assesses the patient's ability to pay for their healthcare services at the time of patient admission based on the Company's verification of the patient's insurance coverage under the Medicare, Medicaid, and other commercial or managed care insurance programs. Medicare contributes to the net service revenue of the Company’s home health, hospice, facility-based, and healthcare innovations services. Medicaid and other payors contribute to the net service revenue of all of the Company's segments. Performance obligations are determined based on the nature of the services provided by the Company. The majority of the Company's performance obligation is to provide services to each patient based on medical necessity and identifies the bundle of services to be provided to achieve the goals established in the contract, while the healthcare innovations segment's performance obligation is largely to provide services under customer contracts. Revenue for performance obligations is satisfied over time and recognized based on actual charges incurred in relation to total expected charges over the measurement period of the performance obligation, which depicts the transfer of services and related benefits received by the patient and customers over the term of the contract to satisfy the obligations. The Company measures the satisfaction of the performance obligation as services are provided. The Company's performance obligations relate to contracts with a duration of less than one year; therefore, the Company has elected to apply the optional exemption provided by ASC 606 - Revenue Recognition, and is not required to disclose the aggregate amount of the transaction price allocated to performance obligations that are unsatisfied or partially unsatisfied at the end of the reporting period. The unsatisfied or partially unsatisfied performance obligations are generally completed when the patients are discharged. The Company determines the transaction price based on gross charges for services provided, reduced by contractual adjustments provided to third-party payors and implicit price concessions. The Company determines estimates of contractual adjustments and implicit price concessions based on historical collection experience. Estimates of contractual allowance and implicit price concessions are periodically reviewed to ensure they encompass the Company's current contract terms, are reflective of the Company's current patient mix, and are indicative of the Company's historic collections to ensure net service revenue is recognized at its net realizable value. The following table sets forth the percentage of net service revenue earned by category of payor for the three and six months ended June 30, 2018 and 2017 : Three Months Ended Six Months Ended 2018 2017 2018 2017 Home health: Medicare 72.9 % 72.4 % 72.3 % 73.0 % Medicaid 1.5 1.2 1.3 1.2 Managed Care, Commercial, and Other 25.6 26.4 26.4 25.8 100.0 % 100.0 % 100.0 % 100.0 % Hospice: Medicare 91.1 % 92.9 % 91.7 % 93.5 % Medicaid 0.6 0.9 0.6 0.6 Managed Care, Commercial, and Other 8.3 6.2 7.7 5.9 100.0 % 100.0 % 100.0 % 100.0 % Home and Community-Based Services: Medicaid 24.7 % 18.0 % 23.1 % 17.3 % Managed Care, Commercial, and Other 75.3 82.0 76.9 82.7 100.0 % 100.0 % 100.0 % 100.0 % Facility-Based Services: Medicare 58.7 % 65.0 % 61.4 % 64.4 % Medicaid — — — — Managed Care, Commercial, and Other 41.3 35.0 38.6 35.6 100.0 % 100.0 % 100.0 % 100.0 % HCI: Medicare 26.7 % — % 26.7 % — % Medicaid 0.4 — 0.4 — Managed Care, Commercial, and Other 72.9 — 72.9 — 100.0 % — % 100.0 % — % Medicare Home Health Services The home health segment's Medicare patients, including certain Medicare Advantage patients, are classified into one of 153 home health resource groups prior to receiving services. Based on the patient’s home health resource group, the Company is entitled to receive a standard prospective Medicare payment for delivering care over a 60 -day period referred to as an episode. The Company elects to use the same 60-day length of episode that Medicare recognizes as standard but accelerates revenue upon discharge to align with a patient's episode length, if less than the expected 60 days, which depicts the transfer of services and related benefits received by the patient over the term of the contract necessary to satisfy the obligations. The Company recognizes revenue based on the number of days elapsed during an episode of care within the reporting period. Final payments from Medicare will reflect base payment adjustments for case-mix and geographic wage differences and 2% sequestration reduction. In addition, final payments may reflect one of four retroactive adjustments to the total reimbursement: (a) an outlier payment if the patient’s care was unusually costly; (b) a low utilization adjustment if the number of visits was fewer than five ; (c) a partial payment if the patient transferred to another provider before completing the episode; or (d) a payment adjustment based upon the level of therapy services required. The retroactive adjustments outlined above are recognized in net service revenue when the event causing the adjustment occurs and during the period in which the services are provided to the patient. The Company reviews these adjustments to ensure that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the retroactive adjustments is subsequently resolved. Net service revenue and related patient accounts receivable are recorded at amounts estimated to be realized from Medicare for services rendered. Hospice Services The Company's hospice services segment is reimbursed by Medicare under a per diem payment system based on the determined need for the patient on a daily basis. The hospice segment receives one of four predetermined daily rates based upon the level of care the Company furnishes. Each level of care is contingent upon the patient's medical necessity and is distinct under contracted performance obligation, which depicts the transfer of services and related benefits received by the patient over the term of the contract to satisfy the obligations. The Company records net service revenue for hospice services based on the contracted per diem rate over time as services are provided, satisfying the performance obligation. Hospice payments are subject to variable consideration through an inpatient cap and an overall Medicare payment cap. The inpatient cap relates to individual programs receiving more than 20% of their total Medicare reimbursement from inpatient care services, and the overall Medicare payment cap relates to individual providers receiving reimbursements in excess of a “cap amount,” determined by Medicare to be payment equal to six months of hospice care for the aggregate base of hospice patients, indexed for inflation. The determination for each cap is made annually based on the 12 -month period ending on October 31 of each year. The Company monitors its limits on a provider-by-provider basis and records an estimate of its liability for reimbursements received in excess of the cap amount in the reporting period. The Company reviews these estimates to ensure that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the retroactive adjustments is subsequently resolved. Facility-Based Services The Company's facility-based services segment is reimbursed primarily by Medicare for services provided under the LTACH prospective payment system. Each LTACH patient is assigned a long-term care diagnosis-related group. The Company is paid a predetermined fixed amount intended to reflect the average cost of treating a Medicare LTACH patient classified in that particular long-term care diagnosis-related group. For selected LTACH patients, the amount may be further adjusted based on length of stay and facility-specific costs, as well as in instances where a patient is discharged and subsequently re-admitted, among other factors. The Company calculates the adjustment based on a historical average of these types of adjustments for LTACH claims paid. Similar to other Medicare prospective payment systems, the rate is also adjusted for geographic wage differences. Net service revenue adjustments resulting from reviews and audits of Medicare cost report settlements are considered implicit price concessions for LTACHs and are measured at expected value. The Company reviews these estimates to ensure that it is probable that a significant reversal in the amount of LTACH services cumulative revenue recognized will not occur when the uncertainty associated with the retroactive adjustments is subsequently resolved. Net service revenue for the Company’s LTACH services are satisfied over time and recognized based on actual charges incurred in relation to total expected charges, which depicts the transfer of services and related benefits received by the customer over the term of the contract to satisfy the obligations. Non-Medicare Revenues Substantially all remaining revenues are derived from services provided under a per visit, per hour or unit basis, per assessment or per member per month basis for which revenues are calculated and recorded using payor-specific or patient-specific fee schedules based on the contracted rates in each underlying third party payor or services agreement. Net service revenue is recognized as such services are provided and costs for delivery of such services are incurred. Contingent Service Revenues The Company’s Healthcare Innovations segment provides strategic health management services to Accountable Care Organizations (“ACOs”) that have been approved to participate in the Medicare Shared Savings Program (“MSSP.”) The HCI segment has service agreements with ACOs that provide for sharing of MSSP payments received by the ACO, if any. ACOs are legal entities that contract with Centers for Medicare and Medicaid Services ("CMS") to provide services to the Medicare fee-for-service population with the goal of providing better care for individuals, improving health for populations and lowering costs. ACOs share savings with CMS to the extent that the actual costs of serving assigned beneficiaries are below certain trended benchmarks of such beneficiaries and certain quality performance measures are achieved. The MSSP is relatively new and therefore has limited historical experience, which impacts the Company’s ability to accurately accumulate and interpret the data available for calculating an ACOs’ shared savings, if any. No net service revenue has been recognized related to potential MSSP payments for savings generated for the program periods ended December 31, 2017 or 2018 , if any. Accounts Receivable The Company reports accounts receivable at amounts ultimately expected to be collected. Accounts receivable are uncollateralized and consist of amounts due from Medicare, Medicaid, other third-party payors, and patients. The credit risk for other concentrations of receivables is limited due to the significance of Medicare as the primary payor. The Company believes the credit risk associated with its Medicare accounts, which have historically exceeded 50% of its patient accounts receivable, is limited due to (i) the historical collection rate from Medicare and (ii) the fact that Medicare is a U.S. government payor. The Company does not believe that there are any other concentrations of receivables from any particular payor that would subject it to any significant credit risk in the collection of accounts receivable. A portion of the estimated Medicare prospective payment system reimbursement from each submitted home nursing episode is received in the form of a request for anticipated payment (“RAP”). The Company submits a RAP for 60% of the estimated reimbursement for the initial episode at the start of care. The full amount of the episode is billed after the episode has been completed. The RAP is recouped and the payment for the entire episode is paid. If a final bill is not submitted within the greater of 120 days from the start of the episode, or 60 days from the date the RAP was paid, any RAP received for that episode will be recouped by Medicare from any other Medicare claims in process for that particular provider. The RAP and final claim must then be resubmitted. For subsequent episodes of care contiguous with the first episode for a particular patient, the Company submits a RAP for 50% instead of 60% of the estimated reimbursement. The Company’s Medicare population is paid at prospectively set amounts that can be determined at the time services are rendered. The Company’s Medicaid reimbursement is based on a predetermined fee schedule applied to each individual service it provides. The Company’s managed care contracts are structured similarly to either the Medicare or Medicaid payment methodologies. The Company is able to calculate its actual amount due at the patient level and adjust the gross charges down to the actual amount at the time of billing. This negates the need to record an estimated contractual allowance when reporting net service revenue for each reporting period. Other Significant Accounting Policies Earnings Per Share Basic per share information is computed by dividing the relevant amounts from the condensed consolidated statements of income by the weighted-average number of shares outstanding during the period, under the treasury stock method. Diluted per share information is also computed using the treasury stock method, by dividing the relevant amounts from the condensed consolidated statements of income by the weighted-average number of shares outstanding plus potentially dilutive shares. The following table sets forth shares used in the computation of basic and diluted per share information and, with respect to the data provided for the three and six months ended June 30, 2018 , includes shares of the Company issued to former stockholders of Almost Family in connection with the Merger.

Assets Held for Sale As of June 30, 2018, assets held for sale includes the land and building and all related equipment and fixtures of one closed hospice facility, which was acquired in the Merger that the Company is actively marketing and intends to sell. Recently Adopted Accounting Pronouncements On May 28, 2014 , the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers , ("ASU 2014-09") which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 replaced most existing revenue recognition guidance in U.S. GAAP. The Company adopted the new standard on January 1, 2018 , and elected to adopt it using the full retrospective method. In August 2016 , the FASB issued ASU No. 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments , which addresses eight classification issues related to the statement of cash flows. This ASU is effective for annual and interim periods in fiscal years beginning after December 15, 2017 . Early adoption is permitted, including adoption in an interim period. Entities should apply this ASU using a retrospective transition method to each period presented. There is no material impact to the Company's interim financial statements upon adoption of ASU 2016-15. In January 2017 , the FASB issued ASU 2017-01, Business Combinations: Clarifying the Definition of a Business, which assist entities with evaluating whether a set of transferred assets and activities is a business . This ASU is effective for annual and interim period in fiscal years beginning after December 15, 2017 . The impact on the Company's consolidated financial statements and related disclosures will depend on facts and circumstances of any specific future transactions as evaluated under the new guidance. Recently Issued Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases , ("ASU 2016-02") which requires lessees to recognize qualifying leases on the statement of financial position. Qualifying leases will be classified as right-of-use assets and lease liabilities. The new standard is effective on January 1, 2019 . Early adoption is permitted. ASU 2016-02 mandates a modified retrospective transition method for all entities. The Company anticipates that the adoption of ASU 2016-02 will result in a significant increase in total assets and total liabilities. The Company continues to evaluate the effect that ASU 2016-02 will have on its related disclosures. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other: Simplifying the Test for Goodwill Impairment , which requires an entity to no longer perform a hypothetical purchase price allocation to measure goodwill impairment. Instead, impairment will be measured using the difference between the carrying amount and the fair value of the reporting unit. This ASU is effective for annual and interim periods in fiscal years beginning after December 15, 2019. Early adoption is permitted for goodwill impairment tests with measurement dates on or after January 1, 2017.

Equity [Abstract]
Stockholder's Equity	Stockholder’s Equity Equity Based Awards At the LHC Group, Inc. 2018 Annual Meeting of Stockholders held on June 7, 2018, the stockholders of the Company approved the adoption of the LHC Group, Inc. 2018 Incentive Plan (the "2018 Incentive Plan") to replace the Company's 2010 Long Term Incentive Plan. The 2018 Incentive Plan will be administered by the Compensation Committee of the Company’s Board of Directors. The total number of shares of the Company's common stock originally reserved and available for issuance pursuant to awards granted under the 2018 Incentive Plan was 2,000,000 , plus an additional number of shares (not to exceed 300,000 ) underlying stock awards granted under the Company's 2010 Long-Term Incentive Plan (the "Prior Plan") that terminate, expire or forfeited. As of June 30, 2018, there were approximately 210,544 shares of our common stock subject to outstanding awards, and approximately 2,000,000 shares of our common stock reserved and available for future awards, under the 2018 Incentive Plan. A variety of discretionary awards for employees, officers, directors, and consultants are authorized under the 2018 Incentive Plan, including incentive or non-qualified stock options and restricted stock, restricted stock units and performance-based awards. All awards must be evidenced by a written award certificate which will include the provisions specified by the Compensation Committee of the Board of Directors. The Compensation Committee determines the exercise price for stock options, which cannot be less than the fair market value of the Company’s common stock as of the date of grant. Almost Family had Stock and Incentive Compensation Plans that provided for stock awards of the Company’s common stock to employees, non-employee directors or independent contractors. Almost Family issued restricted share and/or option awards to employees and non-employee directors. Under the change in control provisions of the Almost Family plans, all outstanding restricted stock, performance restricted stock, and options became non-forfeitable in conjunction with the Merger. Each unvested restricted share award issued by Almost Family that was outstanding immediately prior to the Merger converted into a restricted stock award to acquire shares of the Company on the same terms and conditions rounded up or down to the nearest whole share, determined by multiplying the number of shares of Almost Family common stock subject to such restricted share award by the exchange ratio. Each stock option to purchase shares of Almost Family that was outstanding immediately prior to the Merger converted into an option to purchase shares of the Company on the same terms and conditions, (A) the number of shares of LHC common stock, rounded down to the nearest whole share, determined by multiplying (I) the total number of shares of Almost Family common stock by (II) the exchange ratio, and (B) at a per-share exercise price, rounded up to the nearest whole cent, equal to the quotient determined by dividing (I) the exercise price per share of Almost Family common stock by (II) the exchange ratio. Share Based Compensation Nonvested Stock During the six months ended June 30, 2018 , the Company’s independent directors were granted 13,600 nonvested shares of common stock under the Second Amended and Restated 2005 Non-Employee Directors Compensation Plan. The shares vest 100% on the one year anniversary date. During the six months ended June 30, 2018 , four new directors were granted 14,000 nonvested shares of common stock under the Second Amended and Restated 2005 Non-Employee Directors Compensation Plan. The shares vest 33% at the grant date, then 33% each year on the anniversary date until the third year. The shares were drawn from the 2,300,000 shares of common stock reserved for issuance under the 2018 Incentive Plan. During the six months ended June 30, 2018 , employees were granted 213,105 nonvested shares of common stock pursuant to the 2010 Incentive Plan. The shares vest over a period of five years , conditioned on continued employment. The fair value of nonvested shares of common stock is determined based on the closing trading price of the Company’s common stock on the grant date. The weighted average grant date fair value of nonvested shares of common stock granted during the six months ended June 30, 2018 was $62.35 . The following table represents the nonvested stock activity for the six months ended June 30, 2018 : Restricted stock Options Number of shares Weighted average grant date fair value Number of shares Weighted average grant date fair value Nonvested shares outstanding as of December 31, 2017 529,465 $ 37.34 — $ — Granted 240,705 $ 62.35 — $ — Acquired — $ — 270,710 $ 36.48 Vested or exercised (176,385 ) $ 34.93 (10,727 ) $ 29.08 Nonvested shares outstanding as of June 30, 2018 593,785 $ 48.20 259,983 $ 36.66 As of June 30, 2018 , there was $23.4 million of total unrecognized compensation cost related to nonvested shares of common stock granted. That cost is expected to be recognized over the weighted average period of 3.40 years . The Company records compensation expense related to nonvested stock awards at the grant date for shares of common stock that are awarded fully vested, and over the vesting term on a straight line basis for shares of common stock that vest over time. The Company recorded $3.9 million and $3.1 million of compensation expense related to nonvested stock grants for each of the six months ended June 30, 2018 and 2017 . Employee Stock Purchase Plan In 2006, the Company adopted the Employee Stock Purchase Plan whereby eligible employees may purchase the Company’s common stock at 95% of the market price on the last day of the calendar quarter. There were 250,000 shares of common stock initially reserved for the plan. In 2013 , the Company adopted the Amended and Restated Employee Stock Purchase Plan, which reserved an additional 250,000 shares of common stock to the plan. The table below details the shares of common stock issued during 2018 : Number of shares Per share price Shares available as of December 31, 2017 171,069 Shares issued during the three months ended March 31, 2018 5,534 $ 58.19 Shares issued during the three months ended June 30, 2018 5,171 $ 58.48 Shares available as of June 30, 2018 160,364 Treasury Stock In conjunction with the vesting of the nonvested shares of common stock, recipients incur personal income tax obligations. The Company allows the recipients to turn in shares of common stock to satisfy minimum tax obligations. During the six months ended June 30, 2018 , the Company redeemed 63,161 shares of common stock valued at $3.9 million , related to these tax obligations. In addition, the Company redeemed 5,485 shares of common stock valued at $0.2 million , related to the exercise of Almost Family options. Such shares are held as treasury stock and are available for reissuance by the Company.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Contingencies Regulatory Matters The Company provides services in a highly regulated industry and is a party to various proceedings and regulatory and other governmental and internal audits and investigations in the ordinary course of business (including audits by Zone Program Integrity Contractors ("ZPICs") and Recovery Audit Contractors ("RACs") and investigations resulting from the Company's obligation to self-report suspected violations of law). Management cannot predict the ultimate outcome of any regulatory and other governmental and internal audits and investigations. While such audits and investigations are the subject of administrative appeals, the appeals process, even if successful, may take several years to resolve. The Department of Justice, CMS, or other federal and state enforcement and regulatory agencies may conduct additional investigations related to the Company's businesses. These audits and investigations have caused and could potentially continue to cause delays in collections, recoupments from governmental payors. Currently, the Company has recorded $16.9 million in other assets, which are from government payors related to the disputed finding of pending appeals of ZPIC audits. Additionally, these audits may subject the Company to sanctions, damages, extrapolation of damage findings, additional recoupments, fines, and other penalties (some of which may not be covered by insurance), which may, either individually or in the aggregate, have a material adverse effect on the Company's business and financial condition. Merger Related Litigation On January 18, 2018, Jordan Rosenblatt, a purported shareholder of Almost Family filed a complaint for violations of the Securities Exchange Act of 1934 in the United States District Court for the Western District of Kentucky, styled Rosenblatt v. Almost Family, Inc., et al. , Case No. 3:18-cv-40-TBR (the “Rosenblatt Action”). The Rosenblatt Action was filed against the Company, Almost Family, Almost Family’s board of directors, and Hammer Merger Sub. The complaint in the Rosenblatt Action (“Rosenblatt Complaint”) asserts, among other things, that the Form S-4 Registration Statement (“Registration Statement”) filed on December 21, 2017 in connection with the Merger contained false and misleading statements with respect to the Merger. The Rosenblatt Action sought, among other things, an injunction enjoining the Merger from closing and an award of attorneys’ fees and costs. In addition to the Rosenblatt Action, two additional complaints were filed against Almost Family in the United States District Court for the District of Delaware (the "Delaware Actions") alleging similar violations as the Rosenblatt Action. These Delaware Actions also sought, among other things, an injunction to enjoin both the vote of the Almost Family stockholders with respect to the Merger and the closing of the Merger, monetary damages and an award of attorneys’ fees and costs from Almost Family. On February 22, 2018, plaintiffs in the Delaware Actions moved for a preliminary injunction to enjoin the merger of Almost Family and Merger Sub. Then, on March 2, 2018, the Delaware Actions were transferred to the United States District Court for the Western District of Kentucky. Shortly thereafter, on March 12, 2018, Almost Family, LHC and Merger Sub opposed the plaintiffs’ motion for a preliminary injunction, and the court heard oral argument on the plaintiffs’ motion for a preliminary injunction on March 19, 2018. On March 22, 2018, the court denied plaintiffs’ motion for preliminary injunction. The next day, on March 23, 2018, one of the plaintiffs in the Delaware Actions moved to consolidate the Delaware Actions with the Rosenblatt Action and for the appointment of a lead plaintiff, and that motion is pending before the court. We believe that the claims asserted in these lawsuits are entirely without merit and intend to defend these lawsuits vigorously. Other Litigation We are involved in various other legal proceedings arising in the ordinary course of business. Although the results of litigation cannot be predicted with certainty, we believe the outcome of pending litigation will not have a material adverse effect, after considering the effect of our insurance coverage, on our consolidated financial information. Joint Venture Buy/Sell Provisions Most of the Company’s joint ventures include a buy/sell option that grants to the Company and its joint venture partners the right to require the other joint venture party to either purchase all of the exercising member’s membership interests or sell to the exercising member all of the non-exercising member’s membership interest, at the non-exercising member’s option, within 30 days of the receipt of notice of the exercise of the buy/sell option. In some instances, the purchase price is based on a multiple of the historical or future earnings before income taxes and depreciation and amortization of the equity joint venture at the time the buy/sell option is exercised. In other instances, the buy/sell purchase price will be negotiated by the partners and subject to a fair market valuation process. The Company has not received notice from any joint venture partners of their intent to exercise the terms of the buy/sell agreement nor has the Company notified any joint venture partners of its intent to exercise the terms of the buy/sell agreement. Compliance The laws and regulations governing the Company’s operations, along with the terms of participation in various government programs, regulate how the Company does business, the services offered and its interactions with patients and the public. These laws and regulations, and their interpretations, are subject to frequent change. Changes in existing laws or regulations, or their interpretations, or the enactment of new laws or regulations could materially and adversely affect the Company’s operations and financial condition. The Company is subject to various routine and non-routine governmental reviews, audits and investigations. In recent years, federal and state civil and criminal enforcement agencies have heightened and coordinated their oversight efforts related to the health care industry, including referral practices, cost reporting, billing practices, joint ventures and other financial relationships among health care providers. Violation of the laws governing the Company’s operations, or changes in the interpretation of those laws, could result in the imposition of fines, civil or criminal penalties and/or termination of the Company’s rights to participate in federal and state-sponsored programs and suspension or revocation of the Company’s licenses. The Company believes that it is in material compliance with all applicable laws and regulations.

Noncontrolling Interest [Abstract]
Noncontrolling interest	Noncontrolling interest The Company classifies noncontrolling interests of its joint venture parties based upon a review of the legal provisions governing the redemption of such interests. In each of the Company’s joint ventures, those provisions are embodied within the joint venture’s operating agreement. For joint ventures with operating agreement provisions that establish an obligation for the Company to purchase the third party partners’ noncontrolling interests other than as a result of events that lead to a liquidation of the joint venture, such noncontrolling interests are classified as redeemable noncontrolling interests in temporary equity. For joint ventures with operating agreement provisions that establish an obligation that the Company purchase the third party partners’ noncontrolling interests, but which obligation is triggered by events that lead to a liquidation of the joint venture, such noncontrolling interests are classified as nonredeemable noncontrolling interests in permanent equity. Additionally, for joint ventures with operating agreement provisions that do not establish an obligation for the Company to purchase the third party partners’ noncontrolling interests (e.g., where the Company has the option, but not the obligation, to purchase the third party partners’ noncontrolling interests), such noncontrolling interests are classified as nonredeemable noncontrolling interests in permanent equity. The Company’s equity joint ventures that are classified as redeemable noncontrolling interests are subject to operating agreement provisions that require the Company to purchase the noncontrolling partner’s interest upon the occurrence of certain triggering events, which are defined as the bankruptcy of the partner or the partner’s exclusion from the Medicare or Medicaid programs. These triggering events and the related repurchase provisions are specific to each redeemable equity joint venture, since the triggering of a repurchase obligation for any one redeemable noncontrolling interest in an equity joint venture does not necessarily impact any of the other redeemable noncontrolling interests in other equity joint ventures. Upon the occurrence of a triggering event requiring the purchase of a redeemable noncontrolling interest, the Company would be required to purchase the noncontrolling partner’s interest based upon a valuation methodology set forth in the applicable joint venture agreement. Redeemable noncontrolling interests and nonredeemable noncontrolling interests are initially recorded at their fair value as of the closing date of the transaction establishing the joint venture. Such fair values are determined using various accepted valuation methods, including the income approach, the market approach, the cost approach, and a combination of one or more of these approaches. A number of facts and circumstances concerning the operation of the joint venture are evaluated for each transaction, including (but not limited to) the ability to choose management, control over acquiring or liquidating assets, and controlling the joint venture’s strategy and direction, in order to determine the fair value of the noncontrolling interest. Based upon the Company’s evaluation of the redemption provisions concerning redeemable noncontrolling interests as of June 30, 2018 , the Company determined in accordance with authoritative accounting guidance that it was not probable that an event otherwise requiring redemption of any redeemable noncontrolling interest would occur (i.e., the date for such event was not set or such event is not certain to occur). Therefore, none of the redeemable noncontrolling interests were identified as mandatorily redeemable interests at such times, and the Company did not record any values in respect of any mandatorily redeemable interests. Subsequent to the closing date of the transaction establishing the joint venture, the Company records adjustments to the carrying amounts of noncontrolling interests during each reporting period to reflect (a) comprehensive income (loss) attributed to each noncontrolling interest, which is calculated by multiplying the noncontrolling interest percentage by the comprehensive income (loss) of the joint venture’s operations, (b) dividends paid to the noncontrolling interest partner, and (c) any other transactions that increase or decrease the Company’s ownership interest in each joint venture, as a result of which the Company retains its controlling interest. If the Company determines that, based upon its analysis as of the end of each reporting period in accordance with authoritative accounting guidance, that it is not probable that an event would occur to otherwise require the redemption of a redeemable noncontrolling interest (i.e., the date for such event is not set or such event is not certain to occur), then the Company does not adjust the recorded amount of such redeemable noncontrolling interest. The carrying amount of each redeemable equity instrument presented in temporary equity for the six months ended June 30, 2018 is not less than the initial amount reported for each instrument. The following table summarizes the activity of noncontrolling interest-redeemable for the six months ended June 30, 2018 (amounts in thousands): Balance as of December 31, 2017 $ 13,393 Net income attributable to noncontrolling interest-redeemable 4,855 Noncontrolling interest-redeemable distributions (4,644 ) Acquired noncontrolling interest-redeemable 3,428 Balance as of June 30, 2018 $ 17,032

Segment Reporting [Abstract]
Segment Information	Segment Information In the second quarter of 2018, in recognition of the changes to the Company's business segments resulting from the addition of Almost Family and its subsidiaries through the Merger, the Company redefined its reporting segments to include (1) home health services, (2) hospice services, (3) home and community-based services, formerly referred to by the Company as community-based services, (4) facility-based services and (5) healthcare innovations (“HCI”). In management’s opinion, this approach provides investors clarity and best aligns with the Company’s internal decision-making processes as viewed by the chief operating decision maker. Reportable segments have been identified based upon how management has organized the business by services provided to customers and how the chief operating decision maker manages the business and allocates resources, consistent with the criteria in ASC 280, Segment Reporting. The home health segment provides skilled medical services in patients’ homes largely to enable recipients to reduce or avoid periods of hospitalization and/or nursing home care. Approximately 72.9% of the home health services segment revenues were generated from the Medicare program, while the balance is generated from Medicaid and private insurance programs. The hospice segment services are largely provided in patients’ homes and generally require specialized hospice nursing skills. Hospice services segment revenues are generated on a per diem basis and are primarily from Medicare, which account for approximately 91.1% of hospice services segment revenues. The home and community-based segment services includes traditional home and community-based services (generally provided by paraprofessional staff such as home health aides) which are generally of a custodial rather than skilled nature. Home and community-based services segment revenues are generated on an hourly basis and are primarily from Medicaid, which account for approximately 24.7% of home and community-based services segment revenues. The facility-based segment services includes services provided through LTACHs, a family health center, two pharmacies, a rural health clinic, and two physical therapy clinics. The facility-based services segment is reimbursed primarily by Medicare under the LTACH prospective payment system, which accounts for approximately 58.7% of facility-based services segment revenue. The HCI segment combines reporting on the Company’s developmental activities outside its other business segments. The HCI segment includes (a) Imperium Health Management, LLC, an ACO enablement company, (b) Long Term Solutions, Inc., an in-home assessment company serving the long-term care insurance industry, and certain assets operated by Advanced Care House Calls, which provides primary medical care for home-bound or home-limited patients with chronic and acute illnesses who have difficulty traveling to a doctor’s office, (c) Ingenios Health Co., a Nurse-Practitioner-oriented and mobile technology-enabled health risk assessment company primarily serving managed care organizations, and (d) an investment in Care Journey (formerly NavHealth, Inc.), a population-health analytics company. These activities are intended ultimately, whether directly or indirectly, to benefit the Company’s patients and payors through the enhanced provision of services in the Company’s other segments. The activities all share a common goal of improving patient experiences and quality outcomes, while lowering costs. They include, but are not limited to, items such as: technology, information, population health management, risk-sharing, care-coordination and transitions, clinical advancements, enhanced patient engagement and informed clinical decision and technology enabled in-home clinical assessments. The accounting policies of the segments are the same as those described in the summary of significant accounting policies, as described in Note 2 of the Notes to Condensed Consolidated Financial Statements, including the adoption of ASU 2014-09. The following tables summarize the Company’s segment information for the three and six months ended June 30, 2018 and 2017 (amounts in thousands): Three Months Ended June 30, 2018 Home health services Hospice services Home and community-based services Facility-based services HCI Total Net service revenue $ 360,276 $ 50,554 52,753 $ 28,304 $ 10,137 $ 502,024 Cost of service revenue 230,293 33,493 40,349 19,307 6,204 329,646 General and administrative expenses 99,162 14,613 11,777 11,088 4,710 141,350 Operating income (loss) 30,821 2,448 627 (2,091 ) (777 ) 31,028 Interest expense (2,256 ) (473 ) (158 ) (159 ) (156 ) (3,202 ) Income (loss) before income taxes and noncontrolling interest 28,565 1,975 469 (2,250 ) (933 ) 27,826 Income tax expense 7,091 483 139 (313 ) (230 ) 7,170 Net income (loss) 21,474 1,492 330 (1,937 ) (703 ) 20,656 Less net income (loss) attributable to noncontrolling interests 3,810 412 (90 ) (207 ) (66 ) 3,859 Net income (loss) attributable to LHC Group, Inc.’s common stockholders $ 17,664 $ 1,080 $ 420 $ (1,730 ) $ (637 ) $ 16,797 Total assets $ 1,306,773 $ 189,447 $ 255,456 $ 66,665 $ 63,329 $ 1,881,670 Three Months Ended June 30, 2017 (as adjusted) Home health services Hospice services Home and community-based services Facility-based services HCI Total Net service revenue $ 192,409 $ 37,851 $ 10,746 $ 16,529 $ — $ 257,535 Cost of service revenue 117,606 24,473 7,986 11,093 — 161,158 General and administrative expenses 55,268 10,743 2,261 5,280 — 73,552 Operating income 19,535 2,635 499 156 — 22,825 Interest expense (630 ) (126 ) (42 ) (42 ) — (840 ) Income before income taxes and noncontrolling interest 18,905 2,509 457 114 — 21,985 Income tax expense 6,757 849 180 6 — 7,792 Net income 12,148 1,660 277 108 — 14,193 Less net income attributable to noncontrolling interests 2,266 480 5 138 — 2,889 Net income (loss) attributable to LHC Group, Inc.’s common stockholders $ 9,882 $ 1,180 $ 272 $ (30 ) $ — $ 11,304 Total assets $ 466,308 $ 138,519 $ 33,292 $ 34,547 $ — $ 672,666 Six Months Ended Home health services Hospice services Home and community-based services Facility-based services HCI Total Net service revenue $ 564,463 $ 93,180 66,844 $ 58,454 $ 10,137 $ 793,078 Cost of service revenue 360,453 61,512 51,139 38,956 6,204 518,264 General and administrative expenses 165,452 27,910 15,075 20,234 4,710 233,381 Operating income 38,558 3,758 630 (736 ) (777 ) 41,433 Interest expense (3,343 ) (690 ) (230 ) (232 ) (157 ) (4,652 ) Income (loss) before income taxes and noncontrolling interest 35,215 3,068 400 (968 ) (934 ) 36,781 Income tax expense 7,813 594 124 (154 ) (230 ) 8,147 Net income (loss) 27,402 2,474 276 (814 ) (704 ) 28,634 Less net income (loss) attributable to noncontrolling interests 6,047 829 (70 ) 102 (66 ) 6,842 Net income (loss) attributable to LHC Group, Inc.’s common stockholders $ 21,355 $ 1,645 $ 346 $ (916 ) $ (638 ) $ 21,792 Six Months Ended (as adjusted) Home health services Hospice services Home and community-based services Facility-based services HCI Total Net service revenue $ 373,067 $ 73,799 $ 21,287 $ 33,631 $ — $ 501,784 Cost of service revenue 229,692 47,746 15,934 22,156 — 315,528 General and administrative expenses 109,190 21,149 4,572 10,652 — 145,563 Operating income 34,185 4,904 781 823 — 40,693 Interest expense (1,215 ) (243 ) (81 ) (81 ) — (1,620 ) Income before income taxes and noncontrolling interest 32,970 4,661 700 742 — 39,073 Income tax expense 11,010 1,508 263 184 — 12,965 Net income 21,960 3,153 437 558 — 26,108 Less net income attributable to noncontrolling interests 4,294 766 13 264 — 5,337 Net income attributable to LHC Group, Inc.’s common stockholders $ 17,666 $ 2,387 $ 424 $ 294 $ — $ 20,771

Income Tax Disclosure [Abstract]
Income Tax Disclosure	2. Income Taxes On December 22, 2017 , the U.S. enacted significant changes to U.S. tax law following the passage and signing of “Tax Cuts and Jobs Act” or the “TCJA”. The TCJA is complex and significantly changes the U.S. corporate income tax system by, among other things, reducing the Federal corporate income tax rate from 35% to 21% . The effective tax rate for the six months ended June 30, 2018 and 2017 benefited from $0.9 million and $1.1 million , respectively, of excess tax benefits associated with stock-based compensation arrangements, which was offset by the effect of capitalized transaction costs related to the Merger during the six months ended June 30, 2018 of $0.9 million . US GAAP prescribes a recognition threshold and measurement attribute for the accounting and financial statement disclosure of tax positions taken or expected to be taken in a tax return. The evaluation of a tax position is a two-step process. The first step requires the Company to determine whether it is more likely than not that a tax position will be sustained upon examination based on the technical merits of the position. The second step requires the Company to recognize in the financial statements each tax position that meets the more likely than not criteria, measured at the amount of benefit that has a greater than 50% likelihood of being realized. The Company’s unrecognized tax benefits would affect the tax rate, if recognized. The Company includes the full amount of unrecognized tax benefits in other noncurrent liabilities in the consolidated balance sheets. The Company anticipates it is reasonably possible an increase or decrease in the amount of unrecognized tax benefits could be made in the next twelve months. However, the Company does not presently anticipate that any increase or decrease in unrecognized tax benefits will be material to the consolidated financial statements. The amounts recognized as of June 30, 2018 was $3.9 million .

Use of Estimates		Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported revenue and expenses during the reporting period. Actual results could differ from those estimates.
Critical Accounting Policies		Critical Accounting Policies The Company’s most critical accounting policies relate to the principles of consolidation and revenue recognition.
Principles of Consolidation		Principles of Consolidation The interim financial information includes all subsidiaries and entities controlled by the Company through direct ownership of majority interest or controlling member ownership of such entities (including, as a result of the Merger, those owned and operated by Almost Family). Third party equity interests in the consolidated joint ventures are reflected as noncontrolling interests in the Company’s interim financial information. See Note 9 of the Notes to Condensed Consolidated Financial Statements. The following table summarizes the percentage of net service revenue earned by type of ownership or relationship the Company had with the operating entity: Three Months Ended Six Months Ended Ownership type 2018 2017 2018 2017 Wholly-owned subsidiaries 59.5 % 53.3 % 55.5 % 53.5 % Equity joint ventures 39.4 45.1 43.0 44.8 Other 1.1 1.6 1.5 1.7 100.0 % 100.0 % 100.0 % 100.0 % All significant intercompany accounts and transactions have been eliminated in the Company’s accompanying interim financial information. Business combinations accounted for under the acquisition method have been included in the interim financial information from the respective dates of acquisition. The Company consolidates equity joint venture entities as the Company has controlling interests in the entities, has voting control over these entities, or has ability to exercise significant influence in the entities. The members of the Company's equity joint ventures participate in profits and losses in proportion to their equity interests. The Company also consolidates entities which have license leasing arrangements as the Company owns 100% of the equity of these subsidiaries. The Company has various management services agreements under which the Company manages certain operations of agencies. The Company does not consolidate these agencies if the Company does not have an ownership interest in, nor does it have an obligation to absorb losses of, or right to receive benefits from the entities that own the agencies.
Revenue Recognition		Revenue Recognition Basis of Presentation The Company adopted ASU No. 2014-09, Revenue from Contracts with Customers , ("ASU 2014-09") on January 1, 2018 on a full retrospective basis, which required the Company to present the prior comparable period as adjusted. The adoption of the standard did not have a material impact on the Company's interim financial statements. The Company did not adjust the opening balance of retained earnings to account for the implementation of the requirements of this standard as there are no timing differences related to the recognition of implicit price concessions as part of net service revenue. All amounts previously classified as provision for bad debts are now classified within the Company's net service revenue. For the three and six months ended June 30, 2018, the Company recorded $7.7 million and $12.6 million , respectively, of implicit price concessions as a direct reduction of net service revenue that would have been recorded as provision for bad debts prior to the adoption of ASU 2014-09. Adoption of the standard impacted the Company's previously reported results as follows (amounts in thousands): As previously reported Adjustment for ASU 2014-09 As adjusted As of December 31, 2017 Condensed Consolidated Balance Sheets Patient accounts receivable $ 161,898 $ — $ 161,898 Allowance for uncollectible accounts 23,556 (23,556 ) — Three Months Ended June 30, 2017 Condensed Consolidated Statements of Income: Net service revenue 260,210 (2,675 ) 257,535 Provision for bad debts 2,675 (2,675 ) — Net income attributable to LHC Group, Inc.'s common stockholders 11,304 — 11,304 Six Months Ended June 30, 2017 Condensed Consolidated Statements of Income: Net service revenue 506,828 (5,044 ) 501,784 Provision for bad debts 5,044 (5,044 ) — Net income attributable to LHC Group, Inc.'s common stockholders 20,771 — 20,771 Condensed Consolidated Statements of Cash Flows: Provision for bad debts 5,044 (5,044 ) — Changes in operating assets and liabilities, net of acquisitions: Receivables (6,970 ) 5,044 (1,926 ) Net service revenue is reported at the amount that reflects the consideration to which the Company expects to receive in exchange for providing services. These amounts are due from Medicare, Medicaid, Managed Care, Commercial, and others for services rendered, and they include implicit price concessions for retroactive revenue adjustments due to actual receipts from third-party payors, settlement of audits, and reviews. The estimated uncollectible amounts due from these payors are considered implicit price concessions that are a direct reduction to net service revenue. The Company assesses the patient's ability to pay for their healthcare services at the time of patient admission based on the Company's verification of the patient's insurance coverage under the Medicare, Medicaid, and other commercial or managed care insurance programs. Medicare contributes to the net service revenue of the Company’s home health, hospice, facility-based, and healthcare innovations services. Medicaid and other payors contribute to the net service revenue of all of the Company's segments. Performance obligations are determined based on the nature of the services provided by the Company. The majority of the Company's performance obligation is to provide services to each patient based on medical necessity and identifies the bundle of services to be provided to achieve the goals established in the contract, while the healthcare innovations segment's performance obligation is largely to provide services under customer contracts. Revenue for performance obligations is satisfied over time and recognized based on actual charges incurred in relation to total expected charges over the measurement period of the performance obligation, which depicts the transfer of services and related benefits received by the patient and customers over the term of the contract to satisfy the obligations. The Company measures the satisfaction of the performance obligation as services are provided. The Company's performance obligations relate to contracts with a duration of less than one year; therefore, the Company has elected to apply the optional exemption provided by ASC 606 - Revenue Recognition, and is not required to disclose the aggregate amount of the transaction price allocated to performance obligations that are unsatisfied or partially unsatisfied at the end of the reporting period. The unsatisfied or partially unsatisfied performance obligations are generally completed when the patients are discharged. The Company determines the transaction price based on gross charges for services provided, reduced by contractual adjustments provided to third-party payors and implicit price concessions. The Company determines estimates of contractual adjustments and implicit price concessions based on historical collection experience. Estimates of contractual allowance and implicit price concessions are periodically reviewed to ensure they encompass the Company's current contract terms, are reflective of the Company's current patient mix, and are indicative of the Company's historic collections to ensure net service revenue is recognized at its net realizable value. The following table sets forth the percentage of net service revenue earned by category of payor for the three and six months ended June 30, 2018 and 2017 : Three Months Ended Six Months Ended 2018 2017 2018 2017 Home health: Medicare 72.9 % 72.4 % 72.3 % 73.0 % Medicaid 1.5 1.2 1.3 1.2 Managed Care, Commercial, and Other 25.6 26.4 26.4 25.8 100.0 % 100.0 % 100.0 % 100.0 % Hospice: Medicare 91.1 % 92.9 % 91.7 % 93.5 % Medicaid 0.6 0.9 0.6 0.6 Managed Care, Commercial, and Other 8.3 6.2 7.7 5.9 100.0 % 100.0 % 100.0 % 100.0 % Home and Community-Based Services: Medicaid 24.7 % 18.0 % 23.1 % 17.3 % Managed Care, Commercial, and Other 75.3 82.0 76.9 82.7 100.0 % 100.0 % 100.0 % 100.0 % Facility-Based Services: Medicare 58.7 % 65.0 % 61.4 % 64.4 % Medicaid — — — — Managed Care, Commercial, and Other 41.3 35.0 38.6 35.6 100.0 % 100.0 % 100.0 % 100.0 % HCI: Medicare 26.7 % — % 26.7 % — % Medicaid 0.4 — 0.4 — Managed Care, Commercial, and Other 72.9 — 72.9 — 100.0 % — % 100.0 % — % Medicare Home Health Services The home health segment's Medicare patients, including certain Medicare Advantage patients, are classified into one of 153 home health resource groups prior to receiving services. Based on the patient’s home health resource group, the Company is entitled to receive a standard prospective Medicare payment for delivering care over a 60 -day period referred to as an episode. The Company elects to use the same 60-day length of episode that Medicare recognizes as standard but accelerates revenue upon discharge to align with a patient's episode length, if less than the expected 60 days, which depicts the transfer of services and related benefits received by the patient over the term of the contract necessary to satisfy the obligations. The Company recognizes revenue based on the number of days elapsed during an episode of care within the reporting period. Final payments from Medicare will reflect base payment adjustments for case-mix and geographic wage differences and 2% sequestration reduction. In addition, final payments may reflect one of four retroactive adjustments to the total reimbursement: (a) an outlier payment if the patient’s care was unusually costly; (b) a low utilization adjustment if the number of visits was fewer than five ; (c) a partial payment if the patient transferred to another provider before completing the episode; or (d) a payment adjustment based upon the level of therapy services required. The retroactive adjustments outlined above are recognized in net service revenue when the event causing the adjustment occurs and during the period in which the services are provided to the patient. The Company reviews these adjustments to ensure that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the retroactive adjustments is subsequently resolved. Net service revenue and related patient accounts receivable are recorded at amounts estimated to be realized from Medicare for services rendered. Hospice Services The Company's hospice services segment is reimbursed by Medicare under a per diem payment system based on the determined need for the patient on a daily basis. The hospice segment receives one of four predetermined daily rates based upon the level of care the Company furnishes. Each level of care is contingent upon the patient's medical necessity and is distinct under contracted performance obligation, which depicts the transfer of services and related benefits received by the patient over the term of the contract to satisfy the obligations. The Company records net service revenue for hospice services based on the contracted per diem rate over time as services are provided, satisfying the performance obligation. Hospice payments are subject to variable consideration through an inpatient cap and an overall Medicare payment cap. The inpatient cap relates to individual programs receiving more than 20% of their total Medicare reimbursement from inpatient care services, and the overall Medicare payment cap relates to individual providers receiving reimbursements in excess of a “cap amount,” determined by Medicare to be payment equal to six months of hospice care for the aggregate base of hospice patients, indexed for inflation. The determination for each cap is made annually based on the 12 -month period ending on October 31 of each year. The Company monitors its limits on a provider-by-provider basis and records an estimate of its liability for reimbursements received in excess of the cap amount in the reporting period. The Company reviews these estimates to ensure that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the retroactive adjustments is subsequently resolved. Facility-Based Services The Company's facility-based services segment is reimbursed primarily by Medicare for services provided under the LTACH prospective payment system. Each LTACH patient is assigned a long-term care diagnosis-related group. The Company is paid a predetermined fixed amount intended to reflect the average cost of treating a Medicare LTACH patient classified in that particular long-term care diagnosis-related group. For selected LTACH patients, the amount may be further adjusted based on length of stay and facility-specific costs, as well as in instances where a patient is discharged and subsequently re-admitted, among other factors. The Company calculates the adjustment based on a historical average of these types of adjustments for LTACH claims paid. Similar to other Medicare prospective payment systems, the rate is also adjusted for geographic wage differences. Net service revenue adjustments resulting from reviews and audits of Medicare cost report settlements are considered implicit price concessions for LTACHs and are measured at expected value. The Company reviews these estimates to ensure that it is probable that a significant reversal in the amount of LTACH services cumulative revenue recognized will not occur when the uncertainty associated with the retroactive adjustments is subsequently resolved. Net service revenue for the Company’s LTACH services are satisfied over time and recognized based on actual charges incurred in relation to total expected charges, which depicts the transfer of services and related benefits received by the customer over the term of the contract to satisfy the obligations. Non-Medicare Revenues Substantially all remaining revenues are derived from services provided under a per visit, per hour or unit basis, per assessment or per member per month basis for which revenues are calculated and recorded using payor-specific or patient-specific fee schedules based on the contracted rates in each underlying third party payor or services agreement. Net service revenue is recognized as such services are provided and costs for delivery of such services are incurred. Contingent Service Revenues The Company’s Healthcare Innovations segment provides strategic health management services to Accountable Care Organizations (“ACOs”) that have been approved to participate in the Medicare Shared Savings Program (“MSSP.”) The HCI segment has service agreements with ACOs that provide for sharing of MSSP payments received by the ACO, if any. ACOs are legal entities that contract with Centers for Medicare and Medicaid Services ("CMS") to provide services to the Medicare fee-for-service population with the goal of providing better care for individuals, improving health for populations and lowering costs. ACOs share savings with CMS to the extent that the actual costs of serving assigned beneficiaries are below certain trended benchmarks of such beneficiaries and certain quality performance measures are achieved. The MSSP is relatively new and therefore has limited historical experience, which impacts the Company’s ability to accurately accumulate and interpret the data available for calculating an ACOs’ shared savings, if any. No net service revenue has been recognized related to potential MSSP payments for savings generated for the program periods ended December 31, 2017 or 2018 , if any.
Accounts Receivable and Allowances for Uncollectible Accounts		Accounts Receivable The Company reports accounts receivable at amounts ultimately expected to be collected. Accounts receivable are uncollateralized and consist of amounts due from Medicare, Medicaid, other third-party payors, and patients. The credit risk for other concentrations of receivables is limited due to the significance of Medicare as the primary payor. The Company believes the credit risk associated with its Medicare accounts, which have historically exceeded 50% of its patient accounts receivable, is limited due to (i) the historical collection rate from Medicare and (ii) the fact that Medicare is a U.S. government payor. The Company does not believe that there are any other concentrations of receivables from any particular payor that would subject it to any significant credit risk in the collection of accounts receivable. A portion of the estimated Medicare prospective payment system reimbursement from each submitted home nursing episode is received in the form of a request for anticipated payment (“RAP”). The Company submits a RAP for 60% of the estimated reimbursement for the initial episode at the start of care. The full amount of the episode is billed after the episode has been completed. The RAP is recouped and the payment for the entire episode is paid. If a final bill is not submitted within the greater of 120 days from the start of the episode, or 60 days from the date the RAP was paid, any RAP received for that episode will be recouped by Medicare from any other Medicare claims in process for that particular provider. The RAP and final claim must then be resubmitted. For subsequent episodes of care contiguous with the first episode for a particular patient, the Company submits a RAP for 50% instead of 60% of the estimated reimbursement. The Company’s Medicare population is paid at prospectively set amounts that can be determined at the time services are rendered. The Company’s Medicaid reimbursement is based on a predetermined fee schedule applied to each individual service it provides. The Company’s managed care contracts are structured similarly to either the Medicare or Medicaid payment methodologies. The Company is able to calculate its actual amount due at the patient level and adjust the gross charges down to the actual amount at the time of billing. This negates the need to record an estimated contractual allowance when reporting net service revenue for each reporting period.
Earnings Per Share		Earnings Per Share Basic per share information is computed by dividing the relevant amounts from the condensed consolidated statements of income by the weighted-average number of shares outstanding during the period, under the treasury stock method. Diluted per share information is also computed using the treasury stock method, by dividing the relevant amounts from the condensed consolidated statements of income by the weighted-average number of shares outstanding plus potentially dilutive shares. The following table sets forth shares used in the computation of basic and diluted per share information and, with respect to the data provided for the three and six months ended June 30, 2018 , includes shares of the Company issued to former stockholders of Almost Family in connection with the Merger.

Recently Adopted Accounting Pronouncements		Recently Adopted Accounting Pronouncements On May 28, 2014 , the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers , ("ASU 2014-09") which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 replaced most existing revenue recognition guidance in U.S. GAAP. The Company adopted the new standard on January 1, 2018 , and elected to adopt it using the full retrospective method. In August 2016 , the FASB issued ASU No. 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments , which addresses eight classification issues related to the statement of cash flows. This ASU is effective for annual and interim periods in fiscal years beginning after December 15, 2017 . Early adoption is permitted, including adoption in an interim period. Entities should apply this ASU using a retrospective transition method to each period presented. There is no material impact to the Company's interim financial statements upon adoption of ASU 2016-15. In January 2017 , the FASB issued ASU 2017-01, Business Combinations: Clarifying the Definition of a Business, which assist entities with evaluating whether a set of transferred assets and activities is a business . This ASU is effective for annual and interim period in fiscal years beginning after December 15, 2017 . The impact on the Company's consolidated financial statements and related disclosures will depend on facts and circumstances of any specific future transactions as evaluated under the new guidance.
Recently Issued Accounting Pronouncements		Recently Issued Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases , ("ASU 2016-02") which requires lessees to recognize qualifying leases on the statement of financial position. Qualifying leases will be classified as right-of-use assets and lease liabilities. The new standard is effective on January 1, 2019 . Early adoption is permitted. ASU 2016-02 mandates a modified retrospective transition method for all entities. The Company anticipates that the adoption of ASU 2016-02 will result in a significant increase in total assets and total liabilities. The Company continues to evaluate the effect that ASU 2016-02 will have on its related disclosures. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other: Simplifying the Test for Goodwill Impairment , which requires an entity to no longer perform a hypothetical purchase price allocation to measure goodwill impairment. Instead, impairment will be measured using the difference between the carrying amount and the fair value of the reporting unit. This ASU is effective for annual and interim periods in fiscal years beginning after December 15, 2019. Early adoption is permitted for goodwill impairment tests with measurement dates on or after January 1, 2017.
