| Accounting Policies [Abstract] | ' |
| Basis of Accounting, Policy [Policy Text Block] | ' |
| Basis of Presentation — The accompanying Interim Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America. The Company is the sole member or shareholder of various consolidated limited liability companies and corporations; each established to operate various acquired skilled nursing and assisted living facilities, home health and hospice operations, urgent care centers and related ancillary services. All intercompany transactions and balances have been eliminated in consolidation. The Company presents noncontrolling interest within the equity section of its consolidated balance sheets. The Company presents the amount of consolidated net income that is attributable to The Ensign Group, Inc. and the noncontrolling interest in its consolidated statements of income. |
| The consolidated financial statements include the accounts of all entities controlled by the Company through its ownership of a majority voting interest and the accounts of any variable interest entities (VIEs) where the Company is subject to a majority of the risk of loss from the VIE's activities, or entitled to receive a majority of the entity's residual returns, or both. The Company assesses the requirements related to the consolidation of VIEs, including a qualitative assessment of power and economics that considers which entity has the power to direct the activities that "most significantly impact" the VIE's economic performance and has the obligation to absorb losses of, or the right to receive benefits that could be potentially significant to, the VIE. The Company's relationship with variable interest entities was not material at June 30, 2014. |
|
| On March 25, 2013, the Company agreed to terms to sell Doctors Express (DRX), a national urgent care franchise system. The asset sale was effective on April 15, 2013. The results of operations for DRX have been classified as discontinued operations for all periods presented (see Note 4, Discontinued Operations) in the accompanying Interim Financial Statements. In addition, the results of operations of DRX and the loss or impairment related to this divestiture have been classified as discontinued operations in the accompanying condensed consolidated statements of operations for all periods presented. |
| Use of Estimates, Policy [Policy Text Block] | ' |
| Estimates and Assumptions — The preparation of Interim Financial Statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. The most significant estimates in the Company’s Interim Financial Statements relate to revenue, allowance for doubtful accounts, intangible assets and goodwill, impairment of long-lived assets, general and professional liability, worker’s compensation, and healthcare claims included in accrued self-insurance liabilities, and income taxes. Actual results could differ from those estimates. |
| Segment Reporting, Policy [Policy Text Block] | ' |
| Business Segments — The Company has a single reportable segment — long-term care services, which includes providing skilled nursing, assisted living, home health and hospice, urgent care and related ancillary services. The Company’s single reportable segment is made up of several individual operating segments grouped together principally based on their geographical locations within the United States. Based on the similar economic and other characteristics of each of the operating segments, management believes the Company meets the criteria for aggregating its operating segments into a single reportable segment. |
| Fair Value of Financial Instruments, Policy [Policy Text Block] | ' |
| Fair Value of Financial Instruments —The Company’s financial instruments consist principally of cash and cash equivalents, debt security investments, accounts receivable, insurance subsidiary deposits, accounts payable and borrowings. The Company believes all of the financial instruments’ recorded values approximate fair values because of their nature or respective short durations. |
| Revenue Recognition, Sales of Services [Policy Text Block] | ' |
| Revenue Recognition — The Company recognizes revenue when the following four conditions have been met: (i) there is persuasive evidence that an arrangement exists; (ii) delivery has occurred or service has been rendered; (iii) the price is fixed or determinable; and (iv) collection is reasonably assured. The Company's revenue is derived primarily from providing healthcare services to residents and is recognized on the date services are provided at amounts billable to the individual. For reimbursement arrangements with third-party payors, including Medicaid, Medicare and private insurers, revenue is recorded based on contractually agreed-upon amounts on a per patient, daily basis. |
| Revenue from the Medicare and Medicaid programs accounted for 70.2% and 70.7% of the Company’s revenue for the three and six months ended June 30, 2014, respectively, and 72.7% and 72.8% for the three and six months ended June 30, 2013, respectively. The Company records revenue from these governmental and managed care programs as services are performed at their expected net realizable amounts under these programs. The Company’s revenue from governmental and managed care programs is subject to audit and retroactive adjustment by governmental and third-party agencies. Consistent with healthcare industry accounting practices, any changes to these governmental revenue estimates are recorded in the period the change or adjustment becomes known based on final settlement. The Company recorded retroactive adjustments to revenue which were not material to the Company's consolidated revenue for the three and six months ended June 30, 2014 and 2013. |
| The Company’s service specific revenue recognition policies are as follows: |
| Skilled Nursing Revenue |
| The Company’s revenue is derived primarily from providing long-term healthcare services to residents and is recognized on the date services are provided at amounts billable to individual residents. For residents under reimbursement arrangements with third-party payors, including Medicaid, Medicare and private insurers, revenue is recorded based on contractually agreed-upon amounts on a per patient, daily basis. The Company records revenue from private pay patients, at the agreed-upon rate, as services are performed. |
| Home Health Revenue |
| Medicare Revenue |
| Net service revenue is recorded under the Medicare prospective payment system based on a 60-day episode payment rate that is subject to adjustment based on certain variables including, but not limited to: (a) an outlier payment if patient care was unusually costly; (b) a low utilization payment adjustment if the number of visits was fewer than five; (c) a partial payment if the patient transferred to another provider or the Company received a patient from another provider before completing the episode; (d) a payment adjustment based upon the level of therapy services required; (e) the number of episodes of care provided to a patient, regardless of whether the same home health provider provided care for the entire series of episodes; (f) changes in the base episode payments established by the Medicare Program; (g) adjustments to the base episode payments for case mix and geographic wages; and (h) recoveries of overpayments. |
| The Company makes adjustments to Medicare revenue on completed episodes to reflect differences between estimated and actual payment amounts, an inability to obtain appropriate billing documentation or authorizations acceptable to the payor and other reasons unrelated to credit risk. Therefore, the Company believes that its reported net service revenue and patient accounts receivable will be the net amounts to be realized from Medicare for services rendered. |
| In addition to revenue recognized on completed episodes, the Company also recognizes a portion of revenue associated with episodes in progress. Episodes in progress are 60-day episodes of care that begin during the reporting period, but were not completed as of the end of the period. Thereby, estimating revenue and recognizing it on a daily basis. |
| Non-Medicare Revenue |
| Episodic Based Revenue - The Company recognizes revenue in a similar manner as it recognizes Medicare revenue for episodic-based rates that are paid by other insurance carriers, including Medicare Advantage programs; however, these rates can vary based upon the negotiated terms. |
| Non-episodic Based Revenue - Revenue is recorded on an accrual basis based upon the date of service at amounts equal to its established or estimated per-visit rates, as applicable. |
| Hospice Revenue |
| Revenue is recorded on an accrual basis based upon the date of service at amounts equal to the estimated payment rates. The estimated payment rates are daily rates for each of the levels of care the Company delivers. The Company makes adjustments to revenue for an inability to obtain appropriate billing documentation or authorizations acceptable to the payor and other reasons unrelated to credit risk. Additionally, as Medicare hospice revenue is subject to an inpatient cap limit and an overall payment cap, the Company monitors its provider numbers and estimates amounts due back to Medicare if a cap has been exceeded. The Company records these adjustments as a reduction to revenue and increases other accrued liabilities. |
| Trade and Other Accounts Receivable, Policy [Policy Text Block] | ' |
| Accounts Receivable and Allowance for Doubtful Accounts — Accounts receivable consist primarily of amounts due from Medicare and Medicaid programs, other government programs, managed care health plans and private payor sources. Estimated provisions for doubtful accounts are recorded to the extent it is probable that a portion or all of a particular account will not be collected. |
| In evaluating the collectability of accounts receivable, the Company considers a number of factors, including the age of the accounts, changes in collection patterns, the composition of patient accounts by payor type and the status of ongoing disputes with third-party payors. On an annual basis, the historical collection percentages are reviewed by payor and by state and are updated to reflect the recent collection experience of the Company. In order to determine the appropriate reserve rate percentages which ultimately establish the allowance, the Company analyzes historical cash collection patterns by payor and by state. The percentages applied to the aged receivable balances are based on the Company’s historical experience and time limits, if any, for managed care, Medicare, Medicaid and other payors. The Company periodically refines its estimates of the allowance for doubtful accounts based on experience with the estimation process and changes in circumstances. |
| Property, Plant and Equipment, Policy [Policy Text Block] | ' |
| Property and Equipment — Property and equipment are initially recorded at their historical cost. Repairs and maintenance are expensed as incurred. Depreciation is computed using the straight-line method over the estimated useful lives of the depreciable assets (ranging from three to 57 years). Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated useful lives or the remaining lease term. |
| Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block] | ' |
| Impairment of Long-Lived Assets — The Company reviews the carrying value of long-lived assets that are held and used in the Company’s operations for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of these assets is determined based upon expected undiscounted future net cash flows from the operations to which the assets relate, utilizing management’s best estimate, appropriate assumptions, and projections at the time. If the carrying value is determined to be unrecoverable from future operating cash flows, the asset is deemed impaired and an impairment loss would be recognized to the extent the carrying value exceeded the estimated fair value of the asset. The Company estimates the fair value of assets based on the estimated future discounted cash flows of the asset. Management has evaluated its long-lived assets and has not identified any asset impairment during the three and six months ended June 30, 2014 or 2013. |
| Goodwill and Intangible Assets, Policy [Policy Text Block] | ' |
| Intangible Assets and Goodwill — Definite-lived intangible assets consist primarily of favorable leases, lease acquisition costs, patient base, facility trade names and customer relationships. Favorable leases and lease acquisition costs are amortized over the life of the lease of the facility, typically ranging from ten to 20 years. Patient base is amortized over a period of four to eight months, depending on the classification of the patients and the level of occupancy in a new acquisition on the acquisition date. Trade names at facilities are amortized over 30 years and customer relationships are amortized over 20 years. |
| The Company's indefinite-lived intangible assets consist of trade names and home health and hospice Medicare licenses. The Company tests indefinite-lived intangible assets for impairment on an annual basis or more frequently if events or changes in circumstances indicate that the carrying amount of the intangible asset may not be recoverable. |
| Goodwill represents the excess of the purchase price over the fair value of identifiable net assets acquired in business combinations. Goodwill is subject to annual testing for impairment. In addition, goodwill is tested for impairment if events occur or circumstances change that would reduce the fair value of a reporting unit below its carrying amount. The Company defines reporting units as the individual operations. The Company performs its annual test for impairment during the fourth quarter of each year. See further discussion at Note 11, Goodwill and Other Indefinite-Lived Intangible Assets. |
| Liability Reserve Estimate, Policy [Policy Text Block] | ' |
| Self-Insurance — The Company is partially self-insured for general and professional liability up to a base amount per claim (the self-insured retention) with an aggregate, one-time deductible above this limit. Losses beyond these amounts are insured through third-party policies with coverage limits per occurrence, per location and on an aggregate basis for the Company. For claims made after January 1, 2013, the combined self-insured retention was $500 per claim, subject to an additional one-time deductible of $1,000 for California facilities and a separate, one-time, deductible of $750 for non-California facilities. For all facilities, except those located in Colorado, the third-party coverage above these limits was $1,000 per occurrence, $3,000 per facility, with a $5,000 blanket aggregate and an additional state-specific aggregate where required by state law. In Colorado, the third-party coverage above these limits was $1,000 per occurrence and $3,000 per facility, which is independent of the aforementioned blanket aggregate applicable to its other 118 facilities. |
| The self-insured retention and deductible limits for general and professional liability and California workers' compensation are self-insured through the Captive, the related assets and liabilities of which are included in the accompanying condensed consolidated balance sheets. The Captive is subject to certain statutory requirements as an insurance provider. These requirements include, but are not limited to, maintaining statutory capital. The Company’s policy is to accrue amounts equal to the actuarially estimated costs to settle open claims of insureds, as well as an estimate of the cost of insured claims that have been incurred but not reported. The Company develops information about the size of the ultimate claims based on historical experience, current industry information and actuarial analysis, and evaluates the estimates for claim loss exposure on a quarterly basis. Accrued general liability and professional malpractice liabilities on an undiscounted basis, net of anticipated insurance recoveries, were $28,574 and $29,204 as of June 30, 2014 and December 31, 2013, respectively. |
| The Company’s operating subsidiaries are self-insured for workers’ compensation liability in California. To protect itself against loss exposure in California with this policy, the Company has purchased individual stop-loss insurance coverage that insures individual claims that exceed $500 for each claim. In Texas, the operating subsidiaries have elected non-subscriber status for workers’ compensation claims and, effective February 1, 2011, the Company has purchased individual stop-loss coverage that insures individual claims that exceed $750 for each claim. The Company’s operating subsidiaries in other states have third party guaranteed cost coverage. In California and Texas, the Company accrues amounts equal to the estimated costs to settle open claims, as well as an estimate of the cost of claims that have been incurred but not reported. The Company uses actuarial valuations to estimate the liability based on historical experience and industry information. Accrued workers’ compensation liabilities are recorded on an undiscounted basis in the accompanying condensed consolidated balance sheets and were $14,297 and $13,883 as of June 30, 2014 and December 31, 2013, respectively. |
| In addition, the Company has recorded an asset and equal liability of $1,814 and $3,280 at June 30, 2014 and December 31, 2013, respectively, in order to present the ultimate costs of malpractice and workers' compensation claims and the anticipated insurance recoveries on a gross basis. |
| The Company provides self-insured medical (including prescription drugs) and dental healthcare benefits to the majority of its employees. The Company is fully liable for all financial and legal aspects of these benefit plans. To protect itself against loss exposure with this policy, the Company has purchased individual stop-loss insurance coverage that insures individual claims that exceed $300 for each covered person with an aggregate individual stop loss deductible of $75. The Company’s accrued liability under these plans recorded on an undiscounted basis in the accompanying condensed consolidated balance sheets was $2,878 and $2,736 at June 30, 2014 and December 31, 2013, respectively. |
| The Company believes that adequate provision has been made in the Interim Financial Statements for liabilities that may arise out of patient care, workers’ compensation, healthcare benefits and related services provided to date. The amount of the Company’s reserves was determined based on an estimation process that uses information obtained from both company-specific and industry data. This estimation process requires the Company to continuously monitor and evaluate the life cycle of the claims. Using data obtained from this monitoring and the Company’s assumptions about emerging trends, the Company, with the assistance of an independent actuary, develops information about the size of ultimate claims based on the Company’s historical experience and other available industry information. The most significant assumptions used in the estimation process include determining the trend in costs, the expected cost of claims incurred but not reported and the expected costs to settle or pay damage awards with respect to unpaid claims. The self-insured liabilities are based upon estimates, and while management believes that the estimates of loss are reasonable, the ultimate liability may be in excess of or less than the recorded amounts. Due to the inherent volatility of actuarially determined loss estimates, it is reasonably possible that the Company could experience changes in estimated losses that could be material to net income. If the Company’s actual liability exceeds its estimates of loss, its future earnings, cash flows and financial condition would be adversely affected. |
| Income Tax, Policy [Policy Text Block] | ' |
| Income Taxes —Deferred tax assets and liabilities are established for temporary differences between the financial reporting basis and the tax basis of the Company’s assets and liabilities at tax rates in effect when such temporary differences are expected to reverse. The Company generally expects to fully utilize its deferred tax assets; however, when necessary, the Company records a valuation allowance to reduce its net deferred tax assets to the amount that is more likely than not to be realized. |
|
| For interim reporting purposes, the provision for income taxes is determined based on the estimated annual effective income tax rate applied to pre-tax income, adjusted for certain discrete items occurring during the period. In determining the effective income tax rate for interim financial statements, the Company must consider expected annual income, permanent differences between financial reporting and tax recognition of income or expense and other factors. When the Company takes uncertain income tax positions that do not meet the recognition criteria, it records a liability for underpayment of income taxes and related interest and penalties, if any. In considering the need for and magnitude of a liability for such positions, the Company must consider the potential outcomes from a review of the positions by the taxing authorities. |
| In determining the need for a valuation allowance, the annual income tax rate for interim periods, or the need for and magnitude of liabilities for uncertain tax positions, the Company makes certain estimates and assumptions. These estimates and assumptions are based on, among other things, knowledge of operations, markets, historical trends and likely future changes and, when appropriate, the opinions of advisors with knowledge and expertise in certain fields. Due to certain risks associated with the Company’s estimates and assumptions, actual results could differ. |
| Noncontrolling Interest [Policy Text Block] | ' |
| Noncontrolling Interest — The noncontrolling interest in a subsidiary is initially recognized at estimated fair value on the acquisition date and is presented within total equity in the Company's condensed consolidated balance sheets. The Company presents the noncontrolling interest and the amount of consolidated net income attributable to The Ensign Group, Inc. in its condensed consolidated statements of income and net income per share is calculated based on net income attributable to The Ensign Group, Inc.'s stockholders. The carrying amount of the noncontrolling interest is adjusted based on an allocation of subsidiary earnings based on ownership interest. |
| Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block] | ' |
| Stock-Based Compensation — The Company measures and recognizes compensation expense for all share-based payment awards made to employees and directors including employee stock options based on estimated fair values, ratably over the requisite service period of the award. Net income has been reduced as a result of the recognition of the fair value of all stock options and restricted stock awards issued, the amount of which is contingent upon the number of future grants and other variables. |
| Derivatives, Policy [Policy Text Block] | ' |
| Derivatives and Hedging Activities — Previously, the Company had an interest-rate swap contract in place. The Company has historically evaluated variable and fixed interest rate risk exposure on a routine basis and to the extent the Company believes that it is appropriate, it will offset most of its variable risk exposure by entering into interest-rate swap agreements. It is the Company's policy to only utilize derivative instruments for hedging purposes (i.e. not for speculation). The Company formally designates its interest rate swap agreements as hedges and documents all relationships between hedging instruments and hedged items. The Company formally assesses effectiveness of its hedging relationships, both at the hedge inception and on an ongoing basis, then measures and records ineffectiveness. The Company would discontinue hedge accounting prospectively (i) if it is determined that the derivative is no longer effective in offsetting change in the cash flows of a hedged item, (ii) when the derivative expires or is sold, terminated or exercised, (iii) if it is no longer probable that the forecasted transaction will occur, or (iv) if management determines that designation of the derivative as a hedge instrument is no longer appropriate. |
|
| Effective May 30, 2014, the Company de-designated its interest rate swap contract that historically qualified for cash flow hedge accounting. This was due to the termination of the interest rate swap agreement related to the early retirement of the Senior Credit Facility. As a result, the loss previously recorded in accumulated other comprehensive loss related to the interest rate swap was recognized in interest expense in the Condensed Consolidated Statements of Income. There was no outstanding interest rate swap contract as of June 30, 2014. |
| Comprehensive Income, Policy [Policy Text Block] | ' |
| Accumulated Other Comprehensive Loss and Total Comprehensive Income (Loss) — Accumulated other comprehensive loss refers to revenue, expenses, gains, and losses that are recorded as an element of stockholders’ equity but are excluded from net income. The Company’s other comprehensive loss consists of net deferred gains and losses on certain derivative instruments accounted for as cash flow hedges. The Company recognized a loss of $1,023, net of taxes of $638, to interest expense from accumulated other comprehensive loss during the three and six months ended June 30, 2014 related to the termination of the interest rate swap agreement. As of June 30, 2014, accumulated other comprehensive losses were $0, in stockholders' equity. As of December 31, 2013, accumulated other comprehensive losses were $1,828, net of tax of $716, or $1,112. |
| New Accounting Pronouncements, Policy [Policy Text Block] | ' |
| Recent Accounting Pronouncements — Except for rules and interpretive releases of the Securities and Exchange Commission (SEC) under authority of federal securities laws and a limited number of grandfathered standards, the Financial Accounting Standards Board (FASB) ASC is the sole source of authoritative GAAP literature recognized by the FASB and applicable to the Company. The Company has reviewed the FASB issued Accounting Standards Update (ASU) accounting pronouncements and interpretations thereof that have effectiveness dates during the periods reported and in future periods. The Company has carefully considered the new pronouncements below that alter previous generally accepted accounting principles and does not believe that any new or modified principles will have a material impact on the Company's reported financial position or operations in the near term. The applicability of any standard is subject to the formal review of the Company's financial management and certain standards are under consideration. |
|
| In April 2014, the FASB issued an accounting standards update that raises the threshold for disposals to qualify as discontinued operations and allows companies to have significant continuing involvement with and continuing cash flows from or to the discontinued operation. It also requires additional disclosures for discontinued operations and new disclosures for individually material disposal transactions that do not meet the definition of a discontinued operation. This guidance will be effective for fiscal years beginning after December 15, 2014, which will be the Company's fiscal year 2015, with early adoption permitted. The Company does not expect the adoption of the guidance will have a material impact on the Company's consolidated financial statements. |
|
| In May 2014, the FASB and IASB issued their final standard on revenue from contracts with customers that outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. The new standard supersedes most current revenue recognition guidance, including industry-specific guidance. This guidance will be effective for fiscal years beginning after December 15, 2016, which will be the Company's fiscal year 2017. Early adoption is not permitted. The Company is currently assessing whether the adoption of the guidance will have a material impact on the Company's consolidated financial statements. |
