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 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, assisted living facilities, and home health and hospice operations. Additionally, our Interim Financial Statements include accounts of our majority owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. The Company presents noncontrolling interest within the equity section of its condensed consolidated balance sheets. Noncontrolling interest that is redeemable at the option of the minority shareholder is presented outside of permanent equity in the mezzanine section as temporary equity in the Company's 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 condensed consolidated statements of income. 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 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, interest rate swaps, and income taxes. Actual results could differ from those estimates. Business Segments — The Company has a single reportable segment — long-term care services, which includes the operation of skilled nursing and assisted living facilities, home health, 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 4 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 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. Revenue from the Medicare and Medicaid programs accounted for 73.8% and 75.6% of the Company’s revenue for the three months ended March 31, 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 that increased revenue by $317 and $546 for the three months ended March 31, 2012 and 2011, respectively. 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 and Hospice Revenue Recognition Episodic Based Revenue —Net service revenue is typically recorded on a 60-day episode payment rate. The Company makes adjustments to 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. The Company records an estimate for the impact of such payment adjustments based on its historical experience. 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. The Company estimates this revenue on a monthly basis based upon historical trends. The primary factors underlying this estimate are the number of episodes in progress at the end of the reporting period, expected Medicare revenue per episode and the Company's estimate of the average percentage complete based on days completed of the episode of care. Non-episodic Based Revenue — Revenue is recorded on an accrual basis based upon the date of service at amounts equal to our 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 we deliver. 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. The Company estimates the impact of these adjustments based on its historical experience, which primarily includes historical collection rates on Medicare claims, and records it during the period services are rendered as an estimated revenue adjustment and as a reduction to its outstanding patient accounts receivable. 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. Equity Investment — The Company's majority-owned subsidiary has a non-marketable equity investment which is accounted for under the equity method. The investment is initially recorded at cost and the Company will adjust the carrying amount for its share of the earnings or losses of the investee after the date of investment. The investment is evaluated periodically for impairment. If it is determined that a decline of the investment is other than temporary, then the investment basis would be written down to fair value and the write-down would be included in earnings as a loss. 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 30 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 impairment during the three months ended March 31, 2012 or 2011. Intangible Assets and Goodwill — Definite-lived intangible assets consist primarily of favorable lease, lease acquisition costs, patient base, facility trade names and franchise 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 franchise relationships are amortized over 25 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 facilities. The Company performs its annual test for impairment during the fourth quarter of each year. The Company did not record any impairment charges during the three months ended March 31, 2012 or 2011. 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 April 1, 2012, the combined self-insured retention was $500 per claim with an aggregate $1,750 deductible limit. 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 $10,000 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 $10,000 blanket aggregate applicable to our other 99 facilities. The self-insured retention and deductible limits for general and professional liability and worker’s 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 recorded on an undiscounted basis in the accompanying condensed consolidated balance sheets were $29,976 and $29,196 as of March 31, 2012 and December 31, 2011, 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 $10,404 and $9,827 as of March 31, 2012 and December 31, 2011, respectively. 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 $250 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 $2,700 and $2,436 at March 31, 2012 and December 31, 2011, respectively. In addition, in accordance with guidance provided by the Financial Accounting Standards Board (FASB) in August 2010, the Company has recorded an asset and equal liability of $2,808 and $2,814 at March 31, 2012 and December 31, 2011, respectively, in order to present the ultimate costs of malpractice claims and the anticipated insurance recoveries on a gross basis. 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. 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 — 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. Noncontrolling interest that has redemption features outside the Company's control is accounted for as redeemable noncontrolling interest and is recorded as temporary equity. Owners of noncontrolling interest in certain of the Company's subsidiaries have the right in certain circumstances to require it to purchase additional ownership interests at an amount as defined in the applicable agreement. The intent of the parties is to approximate fair value at the time of redemption by using a multiple of earnings that is consistent with generally accepted valuation practices. These contingent redemption rights are embedded in the equity security at issuance, are not free-standing instruments, do not represent a de facto financing and are not under the Company's control. 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 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. 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 March 31, 2012, accumulated other comprehensive losses were $2,150, recorded net of tax of $837, or $1,313, in stockholders' equity. As of December 31, 2011, accumulated other comprehensive losses were $2,143, net of tax of $835, or $1,308. Adoption of New Accounting Pronouncements — In December 2011, the FASB indefinitely deferred the provisions that required entities to present reclassification adjustments out of accumulated other comprehensive income by component in both the statement in which net income is presented and the statement in which Other Comprehensive Income is presented (for both interim and annual financial statements). During the deferral period, entities will still need to comply with the existing U.S. GAAP requirements for the presentation of reclassification adjustments. The adoption of this amendment did not have a material effect on the Company's financial statements. In July 2011, the FASB amended its standards on how health care entities present revenue and bad debt expense. Under the new guidance, health care entities are required to present bad debt expense related to patient service revenue as a reduction of patient service revenue (net of contractual allowances and discounts) on the statement of income for entities that do not assess a patient's ability to pay prior to rendering services. Further, it was determined, net presentation of bad debt expense in revenue would only apply to bad debts that are related to patient service revenue, to entities that provide services prior to assessing a patient's ability to pay, or to entities that recognize revenue prior to deciding that collection is reasonably assured. In addition, the final consensus requires health care entities to disclose information about the activity in the allowance for doubtful accounts, such as recoveries and write-offs, by using a mixture of qualitative and quantitative data. It will also require disclosure of the Company's policies for (i) assessing the timing and amount of uncollectible revenue recognized as bad debt expense; and (ii) assessing collectability in the timing and amount of revenue (net of contractual allowances and discounts). The Company adopted the disclosure requirements of this amendment during the first quarter of the current year. The Company determined the requirements for presentation of bad debt expense related to patient service revenue as a reduction of patient service revenue outlined in the amendment is not applicable as the Company assesses each patient's ability to pay prior to rendering services.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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, assisted living facilities, and home health and hospice operations. Additionally, our Interim Financial Statements include accounts of our majority owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. The Company presents noncontrolling interest within the equity section of its condensed consolidated balance sheets. Noncontrolling interest that is redeemable at the option of the minority shareholder is presented outside of permanent equity in the mezzanine section as temporary equity in the Company's 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 condensed consolidated statements of income.

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 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, interest rate swaps, and income taxes. Actual results could differ from those estimates.

Business Segments — The Company has a single reportable segment — long-term care services, which includes the operation of skilled nursing and assisted living facilities, home health, 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 4 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 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.

Revenue from the Medicare and Medicaid programs accounted for 73.8% and 75.6% of the Company’s revenue for the three months ended March 31, 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 that increased revenue by $317 and $546 for the three months ended March 31, 2012 and 2011, respectively.

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 and Hospice Revenue Recognition

Episodic Based Revenue —Net service revenue is typically recorded on a 60-day episode payment rate. The Company makes adjustments to 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. The Company records an estimate for the impact of such payment adjustments based on its historical experience. 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. The Company estimates this revenue on a monthly basis based upon historical trends. The primary factors underlying this estimate are the number of episodes in progress at the end of the reporting period, expected Medicare revenue per episode and the Company's estimate of the average percentage complete based on days completed of the episode of care.

Non-episodic Based Revenue — Revenue is recorded on an accrual basis based upon the date of service at amounts equal to our 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 we deliver. 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. The Company estimates the impact of these adjustments based on its historical experience, which primarily includes historical collection rates on Medicare claims, and records it during the period services are rendered as an estimated revenue adjustment and as a reduction to its outstanding patient accounts receivable. 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.

Equity Investment — The Company's majority-owned subsidiary has a non-marketable equity investment which is accounted for under the equity method. The investment is initially recorded at cost and the Company will adjust the carrying amount for its share of the earnings or losses of the investee after the date of investment. The investment is evaluated periodically for impairment. If it is determined that a decline of the investment is other than temporary, then the investment basis would be written down to fair value and the write-down would be included in earnings as a loss.

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 30 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 impairment during the three months ended March 31, 2012 or 2011.

Intangible Assets and Goodwill — Definite-lived intangible assets consist primarily of favorable lease, lease acquisition costs, patient base, facility trade names and franchise 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 franchise relationships are amortized over 25 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 facilities. The Company performs its annual test for impairment during the fourth quarter of each year. The Company did not record any impairment charges during the three months ended March 31, 2012 or 2011.

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 April 1, 2012, the combined self-insured retention was $500 per claim with an aggregate $1,750 deductible limit. 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 $10,000 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 $10,000 blanket aggregate applicable to our other 99 facilities.

The self-insured retention and deductible limits for general and professional liability and worker’s 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 recorded on an undiscounted basis in the accompanying condensed consolidated balance sheets were $29,976 and $29,196 as of March 31, 2012 and December 31, 2011, 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 $10,404 and $9,827 as of March 31, 2012 and December 31, 2011, respectively.

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 $250 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 $2,700 and $2,436 at March 31, 2012 and December 31, 2011, respectively.

In addition, in accordance with guidance provided by the Financial Accounting Standards Board (FASB) in August 2010, the Company has recorded an asset and equal liability of $2,808 and $2,814 at March 31, 2012 and December 31, 2011, respectively, in order to present the ultimate costs of malpractice claims and the anticipated insurance recoveries on a gross basis.

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.

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 — 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. Noncontrolling interest that has redemption features outside the Company's control is accounted for as redeemable noncontrolling interest and is recorded as temporary equity. Owners of noncontrolling interest in certain of the Company's subsidiaries have the right in certain circumstances to require it to purchase additional ownership interests at an amount as defined in the applicable agreement. The intent of the parties is to approximate fair value at the time of redemption by using a multiple of earnings that is consistent with generally accepted valuation practices. These contingent redemption rights are embedded in the equity security at issuance, are not free-standing instruments, do not represent a de facto financing and are not under the Company's control.

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 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.

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 March 31, 2012, accumulated other comprehensive losses were $2,150, recorded net of tax of $837, or $1,313, in stockholders' equity. As of December 31, 2011, accumulated other comprehensive losses were $2,143, net of tax of $835, or $1,308.

Adoption of New Accounting Pronouncements — In December 2011, the FASB indefinitely deferred the provisions that required entities to present reclassification adjustments out of accumulated other comprehensive income by component in both the statement in which net income is presented and the statement in which Other Comprehensive Income is presented (for both interim and annual financial statements). During the deferral period, entities will still need to comply with the existing U.S. GAAP requirements for the presentation of reclassification adjustments. The adoption of this amendment did not have a material effect on the Company's financial statements.

In July 2011, the FASB amended its standards on how health care entities present revenue and bad debt expense. Under the new guidance, health care entities are required to present bad debt expense related to patient service revenue as a reduction of patient service revenue (net of contractual allowances and discounts) on the statement of income for entities that do not assess a patient's ability to pay prior to rendering services. Further, it was determined, net presentation of bad debt expense in revenue would only apply to bad debts that are related to patient service revenue, to entities that provide services prior to assessing a patient's ability to pay, or to entities that recognize revenue prior to deciding that collection is reasonably assured. In addition, the final consensus requires health care entities to disclose information about the activity in the allowance for doubtful accounts, such as recoveries and write-offs, by using a mixture of qualitative and quantitative data. It will also require disclosure of the Company's policies for (i) assessing the timing and amount of uncollectible revenue recognized as bad debt expense; and (ii) assessing collectability in the timing and amount of revenue (net of contractual allowances and discounts). The Company adopted the disclosure requirements of this amendment during the first quarter of the current year. The Company determined the requirements for presentation of bad debt expense related to patient service revenue as a reduction of patient service revenue outlined in the amendment is not applicable as the Company assesses each patient's ability to pay prior to rendering services.
