SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]  
Basis of Presentation and Significant Accounting Policies [Text Block]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation — The accompanying consolidated financial statements (Financial Statements) have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). The Company is the sole member or shareholder of various consolidated limited liability companies and corporations; each established to operate various acquired healthcare service operations. 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 December 31, 2013.

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 in the accompanying Financial Statements (see Note 4, Discontinued Operations). Certain assets and liabilities included in the sale of DRX have been presented as held for sale in the accompanying consolidated balance sheet as of December 31, 2012. In addition, the results of operations of DRX and the loss or impairment related to this divesture have been classified as discontinued operations in the accompanying consolidated statements of income for all periods presented.
Estimates and Assumptions — The preparation of Financial Statements in conformity with 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 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, other contingent liabilities, interest rate swaps, and income taxes. Actual results could differ from those estimates.

Business Segments — The Company has a single reportable segment — healthcare 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 — The Company’s financial instruments consist principally of cash and cash equivalents, debt security investments, interest rate swap agreements, 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. The interest rate swap is carried at fair value on the balance sheet. The Company’s fixed-rate debt instruments do not actively trade in an established market. The fair values of this debt are estimated by discounting the principal and interest payments at rates available to the Company for debt with similar terms and maturities. See further discussion of debt security investments in Note 6, Fair Value Measurements.
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 72.2%, 73.6% and 75.2% of the Company’s revenue for the years ended December 31, 2013, 2012 and 2011, 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 years ended December 31, 2013, 2012 and 2011.
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.
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.
Cash and cash equivalents Cash and cash equivalents consist of bank term deposits, money market funds and treasury bill related investments with original maturities of three months or less at time of purchase and therefore approximate fair value. The fair value of money market funds is determined based on “Level 1” inputs, which consist of unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets. The Company places its cash and short-term investments with high credit quality financial institutions.
Insurance Subsidiary Deposits and Investments — The Company's captive insurance subsidiary cash and cash equivalents, deposits and investments are designated to support long-term insurance subsidiary liabilities and have been classified as long-term assets. The majority of these deposits and investments are currently held in AA- and A- rated debt security investments and the remainder is held in a bank account with a high credit quality financial institution. See further discussion at Note 6, Fair Value Measurements.
Equity Investment — As of December 31, 2012, one of the Company's subsidiaries had a non-marketable equity investment which was accounted for under the equity method. The investment was initially recorded at cost and the Company adjusted the carrying amount for its share of the earnings or losses of the investee after the date of investment. On April 23, 2013, the Company entered into a common unit redemption agreement with the investee where the non-marketable equity investment was repurchased. See further discussion at Note 12, Restricted and Other Assets.
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 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 years ended December 31, 2013, 2012 or 2011.
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.

Deferred Rent  — Deferred rent represents rental expense (determined on a straight-line basis over the life of the related lease) in excess of actual rent payments.
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 claim, per location and on an aggregate basis for the Company. For claims made after January 1, 2013, the 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 amounts was $1,000 per claim, $3,000 per facility, with a $5,000 blanket aggregate available to both California and non-California operations, separately. In Colorado, the third-party coverage above these limits was $1,000 per claim and $3,000 per facility, which is independent of the aforementioned blanket aggregate applicable to its other 113 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 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, 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.
 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 occurrence. 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 occurrence. 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.
In addition, the Company has recorded an asset and equal liability of $3,280 and $3,219 at December 31, 2013 and December 31, 2012, respectively, in order to present the ultimate costs of malpractice and workers' compensation claims and the anticipated insurance recoveries on a gross basis. See Note 12, Restricted and Other Assets.
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 per each covered member, subject to an additional one-time deductible of $75.
The Company believes that adequate provision has been made in the 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 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.

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 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 — 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 consolidated balance sheets. The Company presents the noncontrolling interest and the amount of consolidated net income attributable to The Ensign Group, Inc. in its 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.

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 and Hedging Activities — The Company evaluates 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. The Company’s derivative is recorded on the balance sheet at its fair value.

Leases and Leasehold Improvements — At the inception of each lease, the Company performs an evaluation to determine whether the lease should be classified as an operating or capital lease. The Company records rent expense for leases that contain scheduled rent increases on a straight-line basis over the term of the lease. The lease term used for straight-line rent expense is calculated from the date the Company is given control of the leased premises through the end of the lease term. The lease term used for this evaluation also provides the basis for establishing depreciable lives for buildings subject to lease and leasehold improvements, as well as the period over which the Company records straight-line rent expense.

Accumulated Other Comprehensive Loss and Total Comprehensive Income — 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. As of December 31, 2013 accumulated other comprehensive loss was $1,828, recorded net of tax of $716, or $1,112. As of December 31, 2012, accumulated other comprehensive loss was $2,866, recorded net of tax of $1,121, or $1,745.

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 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.

Additionally, the FASB and the International Accounting Standards Board are working on joint convergence projects to address accounting differences between GAAP and International Financial Reporting Standards in order to support their commitment to achieve a single set of high-quality global accounting standards. One of the projects under deliberation includes accounting for leases. If enacted in its current draft form, the Company anticipates that the lease accounting proposal could impact its consolidated financial statements; however, the FASB's standard-setting process is ongoing and until new standards have been finalized and issued, the Company cannot quantify and determine the impact on its consolidated financial statements that may result from such future changes.
