Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“US GAAP”) requires management to make estimates and assumptions that affect the reported amounts in the Company's accompanying consolidated financial statements and notes to the consolidated financial statements. Actual results could differ from those estimates. A description of the significant accounting policies and a discussion of the significant estimates and judgments associated with such policies are described below. Principles of Consolidation The consolidated financial statements include all subsidiaries and entities controlled by the Company through direct ownership of majority interest or controlling member ownership of such entities. Third party equity interests in the consolidated joint ventures are reflected as noncontrolling interests in the Company’s consolidated financial statements. All significant intercompany accounts and transactions have been eliminated in consolidation. All business combinations accounted for under the acquisition method have been included in the consolidated financial statements from the respective dates of acquisition. The Company consolidates equity joint venture entities as the Company has controlling interests, has voting control over these entities, or has ability to exercise significant influence in these entities. The members of the Company's equity joint ventures participate in profits and losses in proportion to their equity interests. The Company, through wholly owned subsidiaries, leases home health licenses necessary to operate certain of its home nursing and hospice agencies. As with wholly owned subsidiaries, the Company owns 100% of the equity of these entities and consolidates them based on such ownership. Reclassification and Immaterial Correction of an Error The Company has reclassified certain amounts relating to its prior year results to conform to its current period presentation. These reclassifications have not changed the results of operations of prior years. During the year ended December 31, 2019, the Company increased the reported balance of common stock by $2,000 , increased the reported number of common shares issued by 198,934 shares, decreased the reported balance of treasury stock by $1,000 , increased the reported number of treasury shares by 70,708 , and decreased the reported balances of Additional paid-in-capital by $3,000 for the year ended December 31, 2018 due to (1) the exclusion of reporting the number of common shares issued in conjunction with the Company's purchase of an additional controlling interest in a joint venture and (2) the exclusion of reporting the number of common shares issued as a result of the exercise of certain outstanding stock options and the number of treasury shares redeemed to pay income tax associated with such stock option exercises. The Company has evaluated the effects both qualitatively and quantitatively, and concluded that they did not have a material impact on previously issued financial statements for the year ended December 31, 2018. Revenue Recognition Basis of Presentation Net service revenue from contracts with customers is recognized in the period the performance obligations are satisfied under the Company's contracts by transferring the requested services to patients in amounts that reflect the consideration to which is expected to be received in exchange for providing patient care, which is the transaction price allocated to the services provided in accordance with Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606) and ASU 2015-14 , Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date (collectively, "ASC 606"). Net service revenue is recognized as performance obligations are satisfied, which can vary depending on the type of services provided. The performance obligation is the delivery of patient care in accordance with the requested services outlined in physicians' orders, which are based on specific goals for each patient. The performance obligations are associated with contracts in duration of less than one year; therefore, the optional exemption provided by ASC 606 was elected resulting in the Company not being required to disclose the aggregate amount of the transaction price allocated to the performance obligations that are unsatisfied or partially unsatisfied as of the end of the reporting period. The Company's unsatisfied or partially unsatisfied performance obligations are primarily completed when the patients are discharged and typically occur within days or weeks of the end of the period. The Company determines the transaction price based on gross charges for services provided, reduced by estimates for explicit and implicit price concessions. Explicit price concessions include contractual adjustments provided to patients and third-party payors. Implicit price concessions include discounts provided to self-pay, uninsured patients or other payors, adjustments resulting from regulatory reviews, audits, billing reviews and other matters. Subsequent changes to the estimate of the transaction price are recorded as adjustments to net service revenue in the period of change. Subsequent changes that are determined to be the result of an adverse change in the patient's ability to pay (i.e. change in credit risk) are recorded as a provision for doubtful accounts within general and administrative expenses. Explicit price concessions are recorded for the difference between our standard rates and the contracted rates to be realized from patients, third party payors and others for services provided. Implicit price concessions are recorded for self-pay, uninsured patients and other payors by major payor class based on historical collection experience, aged accounts receivable by payor, and current economic conditions. The implicit price concession represents the difference between amounts billed and amounts expected to be collected based on collection history with similar payors. The Company assesses the ability to collect for the healthcare services provided at the time of patient admission based on the verification of the patient's insurance coverage under Medicare, Medicaid, and other commercial or managed care insurance programs. Amounts due from third-party payors, primarily commercial health insurers and government programs (Medicare and Medicaid), include variable consideration for retroactive revenue adjustments due to settlements of audits and reviews. The Company has determined estimates for price concessions related to regulatory reviews based on historical experience and success rates in the claim appeals and adjudication process. Revenue is recorded at amounts estimated to be realizable for services provided. The following table sets forth the percentage of net service revenue earned by category of payor for each segment for the years ending December 31: 2019 2018 2017 Home Health: Medicare 70.2 % 71.8 % 72.6 % Managed Care, Commercial, and Other 29.8 28.2 27.4 100.0 % 100.0 % 100.0 % Hospice: Medicare 92.0 % 90.7 % 92.9 % Managed Care, Commercial, and Other 8.0 9.3 7.1 100.0 % 100.0 % 100.0 % Home and Community-Based: Medicaid 23.2 % 23.9 % 18.9 % Managed Care, Commercial, and Other 76.8 76.1 81.1 100.0 % 100.0 % 100.0 % Facility-Based: Medicare 56.2 % 59.7 % 63.7 % Managed Care, Commercial, and Other 43.8 40.3 36.3 100.0 % 100.0 % 100.0 % Healthcare Innovations: Medicare 21.6 % 22.8 % — % Managed Care, Commercial, and Other 78.4 77.2 — 100.0 % 100.0 % — % Medicare Home Health Services The home nursing Medicare 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. Revenue is recognized 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 also reflect, but are not limited to, 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 or transferred from another provider before completing the episode; or (d) a payment adjustment based upon the level of therapy services required. Medicare rates are based on the severity of the patient's condition, service needs and goals, and other factors relating to the cost of providing services and supplies, bundled into an episode of care, not to exceed 60 days. An episode starts the first day a billable visit is performed and ends 60 days later or upon discharge, if earlier, with multiple continuous episodes allowed. The Medicare home health benefit requires that beneficiaries be homebound (meaning that the beneficiary is unable to leave their home without a considerable and taxing effort), require intermittent skilled nursing, physical therapy or speech therapy services, and receive treatment under a plan of care established and periodically reviewed by a physician. All Medicare contracts are required to have a signed plan of care which represents a single performance obligation, comprising of the delivery of a series of distinct services that are substantially similar and have a similar pattern of transfer to the customer. Accordingly, the Company accounts for the series of services ("episode") as a single performance obligation satisfied over time, as the customer simultaneously receives and consumes the benefits of the goods and services provided. Expected Medicare revenue per episode is recognized based on the number of days elapsed during an episode of care within the reporting period. The base episode payment can be adjusted based on each patient's health including clinical condition, functional abilities, and service needs, as well as for the applicable geographic wage index, low utilization, patient transfers and other factors. The services covered by the episode payment include all disciplines of care in addition to medical supplies. Medicare can also make various adjustments to payments received resulting from regulatory reviews, audits, billing reviews and other matters. The Company estimates the impact of such adjustments based our historical experience, and records this estimate during the period in which services are rendered as an estimated price concession and a corresponding reduction to patient accounts receivable. A portion of reimbursement from each Medicare episode is billed near the start of each episode, and cash is typically received before all services are rendered. The amount of revenue recognized for episodes of care which are incomplete at period end is based on the number of days elapsed during the episode of care within the reporting period. As of December 31, 2019 and 2018, the difference between the cash received from Medicare for a request for anticipated payment (“RAP”) on episodes in progress and the associated estimated revenue was immaterial and, therefore, the resulting credits were recorded as a reduction to our outstanding patient accounts receivable in our consolidated balance sheets for such periods. Hospice Services The Company records revenue on an accrual basis based upon the date of service at amounts equal to the estimated payment rates. The estimated payment rates are predetermined daily or hourly rates for each of the four levels of care delivered. The Company receives one of four predetermined daily rates based upon the level of care the Company furnishes. The four levels of care are routine care, general inpatient care, continuous home care, and respite care. There are two separate payment rates for routine care: payment for the first 60 days of care and care beyond 60 days. In addition to the two routine rates, the Company may also receive a service intensity add-on ("SIA"). The SIA is based on visits made in the last seven days of life by a registered nurse or medical social worker for patients in a routine level of care. The performance obligation is the delivery of hospice services to the patient, as determined by a physician, each day the patient is on hospice care. Adjustments to Medicare revenue are made from regulatory reviews, audits, billing reviews and other matters. The Company estimates the impact of these adjustments based on our historical experience. 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 its total Medicare reimbursement from inpatient care services and the overall Medicare payment cap relates to individual programs 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, if any, in the reporting period. Facility-Based Services Gross revenue is recorded as services are provided under the long-term acute care hospital (“LTACH”) prospective payment system. Each 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. Non-Medicare Revenue Other sources of net service revenue for all segments fall into Medicaid, managed care or other payers of the Company's services. Medicaid reimbursement is based on a predetermined fee schedule applied to each service provided. Therefore, revenue is recognized for Medicaid services as services are provided based on this fee schedule. The Company's managed care and other payors reimburse the Company based upon a predetermined fee schedule or an episodic basis, depending on the terms of the applicable contract. Accordingly, the Company recognizes revenue from managed care and other payors as services are provided, such costs are incurred, and estimates of expected payments are known for each different payer, thus the Company's revenue is recorded at the estimated transaction price. Contingent Service Revenues The Company's Healthcare Innovations ("HCI") segment provides strategic health management services to Affordable 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 for a specified annual period with the goal of providing better care for the individual, 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 generation of shared savings is the performance obligation of each ACO, which only become certain upon the final issuance of unembargoed calculations by CMS, generally in the third quarter of each year. During the years ended December 31, 2019 and 2018, the HCI segment recorded net service revenue of $2.9 million and $3.7 million , respectively, related to the 2018 and 2017 ACO respective service periods, as certain ACOs served by the HCI segment received a MSSP payment from CMS confirming the performance obligation has been met. Patient Accounts Receivable The Company reports patient accounts receivable from services rendered at their estimated transaction price, which includes price concessions based on the amounts expected to be due from payors. The Company's patient accounts receivable is uncollateralized and primarily consist of amounts due from Medicare, Medicaid, other third-party payors, and to a lesser degree patients. The credit risk from other payors is limited due to the significance of Medicare as the primary payor. The Company believes the credit risk associated with its Medicare accounts 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 significant concentrations from any particular payor that would subject it to any significant credit risk in the collection of patient 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 received for that particular episode is recouped prior to receiving final payment in full. 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% of the estimated reimbursement. The following table sets forth the percentage of patient accounts receivable by payor for the years ended December 31: 2019 2018 Medicare 48.3 % 51.3 % Medicaid 9.4 8.6 Managed Care, Commercial, and Other 42.3 40.1 Total patient accounts receivable 100.0 % 100.0 % Business Combinations The Company accounts for its acquisitions in accordance with ASC 805, "Business Combinations" ("ASC 805") using the acquisition method of accounting. Assets typically acquired consist primarily of Medicare licenses, trade names, certificates of need, and/or non-compete agreements. The assets acquired and liabilities assumed, if any, are measured at fair value on the acquisition date using the appropriate valuation method. The noncontrolling interest associated with joint venture acquisitions is also measured and recorded at fair value as of the acquisition date. Goodwill represents the excess of the cost of an acquired entity over the net amounts assigned to assets acquired and liabilities assumed. The operations of the acquisitions are included in the consolidated financial statements from their respective dates of acquisition. Acquisition transactions that occurred in 2019 and 2018 are further described in Note 3 and Note 4 to the Consolidated Financial Statements included in this Annual Report on Form 10-K. Insurance Programs The Company bears significant risk under its large-deductible workers’ compensation insurance program and its self-insured employee health program. Under the workers’ compensation insurance program, the Company bears risk up to $1.0 million per incident, after which stop-loss coverage is maintained. The Company purchases stop-loss insurance for the employee health plan and bear risk up to $0.3 million per incident. Malpractice and general patient liability claims for incidents which may give rise to litigation have been asserted against the Company by various claimants. The claims are in various stages of processing and some may ultimately be brought to trial. The Company currently carries professional liability insurance coverage on a claims made basis and general liability insurance coverage on an occurrence basis for this exposure with a $0.1 million . The Company also carries Directors and Officers coverage (also on a claims made basis) for potential claims against the Company’s directors and officers, including securities actions, with deductibles ranging from $0.5 million to $1.0 million per claim. The Company records estimated liabilities for its insurance programs based on information provided by the third-party plan administrators, historical claims experience, the life cycle of claims, expected costs of claims incurred but not paid, and expected costs to settle unpaid claims. The Company monitors its estimated insurance-related liabilities and recoveries, if any, on a monthly basis and records amounts due under insurance policies in other current assets, while recording the estimated carrier liability in self-insurance reserves. As facts change, it may become necessary to make adjustments that could be material to the Company’s results of operations and financial condition. Goodwill and Intangible Assets In accordance with ASC 350, "Intangibles - Goodwill and Other" ("ASC 350") goodwill and intangible assets with indefinite lives are reviewed by the Company at least annually for impairment. The Company performs its annual impairment review of goodwill at November 30, and when a triggering event occurs between annual impairment tests. For 2019 and 2018, the Company performed a qualitative assessment of goodwill and determined that it is not more likely than not that the fair values of its reporting units are less than the carrying amounts. The Company has not recognized any goodwill impairment charges in 2019 , 2018 or 2017 related to the annual impairment testing. Components of the Company's reporting units are collections of markets of similar service offerings that operate collaboratively under a house of brands, i.e. multiple brands are used across markets, states, and segments. During the years ended December 31, 2019, 2018, and 2017, the Company recognized an impairment of $0.6 million , $0.6 million , and $1.5 million related to goodwill associated with the closure of underperforming locations. The impairments were calculated using a market approach. Included in intangible assets are definite-lived assets subject to amortization such as non-compete agreements, customer relationships, and defensive assets, which are defined as trade names that are not actively used. Amortization of definite-lived intangible assets is calculated on a straight-line basis over the estimated useful lives of the related assets, ranging from two to nineteen years . Amortization expense for the Company's definite-lived intangible assets for the year ended December 31, 2019, was $1.3 million , and for each of the years ended December 31, 2018 and 2017 was $2.1 million , which was recorded in general and administrative expenses. The Company also has indefinite-lived assets that are not subject to amortization expense such as trade names, certificates of need, and Medicare licenses to conduct specific operations within geographic markets. The Company has concluded that trade names, certificates of need, and licenses have indefinite lives, because there are no legal, regulatory, contractual, economic or other factors that would limit the useful lives of these intangible assets and the Company intends to renew and operate the certificates of need and licenses and use the trade names indefinitely. In some cases, the value of licenses and certificates of need is increased by moratoriums in effect. These indefinite-lived intangible assets are reviewed annually for impairment or more frequently if circumstances indicate impairment may have occurred. To determine whether an indefinite-lived intangible asset is impaired, the Company performs a qualitative assessment to support the conclusion that the indefinite-lived intangible asset is not impaired. Based on the results of that qualitative assessment, the Company may perform a quantitative test. The Company utilizes a relief-from-royalty method in its quantitative impairment test of trade names. Under this method, the fair value of the trade name is determined by calculating the present value of the after-tax cost savings associated with owning the trade names and, therefore, not having to pay royalties for use over its estimated useful life. The Company utilizes the replacement cost approach in its quantitative impairment test for certificates of need and licenses. Under this method, assumptions are made about the cost to replace the certificates of need and licenses. During the twelve months ended December 31, 2019 , 2018 or 2017, the Company did not record an impairment charge related to indefinite-lived intangible assets in the annual impairment testing. During the year ended December 31, 2019, the Company did record $7.1 million related to impairments, of which $6.1 million was related to impairment due to changes in moratorium regulations and $1.0 million was related to the closure of underperforming locations. During 2019, CMS removed all federal moratoria with regard to Medicare provider enrollments in four states. The Medicare licenses were deemed impaired upon the notice of removal. During the year ended December 31, 2018, the Company recognized a disposal of $3.7 million related to intangible assets associated with closures of underperforming locations. The Company did no t recognize any such costs during the year ended December 31, 2017. Due to/from Governmental Entities The Company’s LTACHs are reimbursed for certain activities based on tentative rates. The amounts recorded in due to/from governmental entities on the Company’s consolidated balance sheets relate to settled and open cost reports that are subject to the completion of audits and the issuance of final assessments. Final reimbursement is determined based on submission of annual cost reports and audits by the fiscal intermediary. Adjustments are accrued on an estimated basis in the period the related services were rendered and further adjusted as final settlements are determined. These adjustments are accounted for as changes in estimates. Additionally, reimbursements received in excess of hospice cap amounts are recorded in this account, if any. Property, Building and Equipment Property, building and equipment are recorded at cost. Property, building and equipment acquired in connection with business combinations are recorded at estimated fair value in accordance with the acquisition method of accounting in accordance with ASC 805. Expenditures that increase capacities or extend useful lives are capitalized to the appropriate property, building and equipment accounts. Costs and related accumulated depreciation associated with assets that are sold or retired are written off and any gain or losses are recorded in operating income. Routine repairs and maintenance costs are expensed as incurred. Depreciation is computed using the straight-line method over the estimated useful lives of the individual assets. The estimated useful life of buildings is 39 years , while the estimated useful lives of transportation equipment, fixed equipment, and office furniture and equipment range from 3 to 10 years . The useful life for leasehold improvements is the shorter of the lease term or the expected life of the leasehold improvement. In accordance with ASC 360, "Property, Plant, and Equipment", the Company evaluates its long-lived assets for possible impairment whenever events or changes in circumstances occur that indicate that the carrying amount of the asset may not be recoverable. There were no impairment charges recognized during the periods ended December 31, 2019, 2018 and 2017 . The following table describes the Company’s components of property, building and equipment for the years ended December 31, 2019 and 2018 (amounts in thousands): 2019 2018 Land $ 7,339 $ 6,750 Building and leasehold improvements 36,142 35,474 Transportation equipment 12,470 13,503 Fixed equipment 376 745 Office furniture and medical equipment 94,993 78,344 Construction in progress 16,029 — 167,349 134,816 Less accumulated depreciation 69,441 55,253 Property, building and equipment, net $ 97,908 $ 79,563 Depreciation expense for the years ended December 31, 2019, 2018 and 2017 was $17.0 million , $14.1 million and $11.3 million , respectively, which was recorded in general and administrative expenses. In addition, the Company capitalized $0.2 million in interest costs related to the construction of its home office expansion project. Noncontrolling Interest The Company classifies noncontrolling interests of its joint ventures 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 control over the joint venture’s strategy and direction, in order to determine the fair value of the noncontrolling interest.
