| Basis of Presentation                                                               | Basis of PresentationHealthSouth Corporation, incorporated in Delaware in 1984, including its subsidiaries, is the largest owner and operator of inpatient rehabilitation hospitals in the United States. We operate inpatient rehabilitation hospitals and provide specialized rehabilitative treatment on both an inpatient and outpatient basis. References herein to “HealthSouth,” the “Company,” “we,” “our,” or “us” refer to HealthSouth Corporation and its subsidiaries unless otherwise stated or indicated by context.The accompanying unaudited condensed consolidated financial statements of HealthSouth Corporation and Subsidiaries should be read in conjunction with the consolidated financial statements and accompanying notes filed with the United States Securities and Exchange Commission in HealthSouth’s Annual Report on Form 10-K filed on February 23, 2012 (the “2011 Form 10-K”). The unaudited condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the SEC applicable to interim financial information. Certain information and note disclosures included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America have been omitted in these interim statements, as allowed by such SEC rules and regulations. The condensed consolidated balance sheet as of December 31, 2011 has been derived from audited financial statements, but it does not include all disclosures required by GAAP. However, we believe the disclosures are adequate to make the information presented not misleading.The unaudited results of operations for the interim periods shown in these financial statements are not necessarily indicative of operating results for the entire year. In our opinion, the accompanying condensed consolidated financial statements recognize all adjustments of a normal recurring nature considered necessary to fairly state the financial position, results of operations, and cash flows for each interim period presented.Reclassifications—Effective January 1, 2012, we adopted Accounting Standards Update 2011-07, Healthcare Entities (Topic 954), "Presentation and Disclosure of Patient Service Revenue, Provision for Bad Debts, and the Allowance for Doubtful Accounts for Certain Healthcare Entities," which requires certain healthcare entities to present the provision for doubtful accounts relating to patient service revenue as a deduction from patient service revenue in the statement of operations rather than as an operating expense. All periods presented have been reclassified to conform to this presentation. Our adoption of this standard had no net impact on our financial position, results of operations, or cash flows. This standard also requires healthcare entities to provide enhanced disclosure about their policies for recognizing revenue and assessing bad debts, as well as qualitative and quantitative information about changes in the allowance for doubtful accounts. See the "Net Operating Revenues" and "Allowance for Doubtful Accounts" sections of this note.During the third quarter of 2012, we negotiated with our partner to amend the joint venture agreement related to St. Vincent Rehabilitation Hospital which resulted in a change in accounting for this hospital from the equity method of accounting to a consolidated entity. The amendment revised certain participatory rights held by our joint venture partner resulting in HealthSouth gaining control of this entity from an accounting perspective. See Note 2, Investments in and Advances to Nonconsolidated Affiliates.Net Operating Revenues—During the three and nine months ended September 30, 2012 and 2011, we derived consolidated Net operating revenues from the following payor sources: Three Months Ended September 30, Nine Months Ended September 30, 2012 2011 2012 2011Medicare73.1% 72.0% 73.1% 71.8%Medicaid1.4% 1.6% 1.3% 1.7%Workers’ compensation1.5% 1.6% 1.5% 1.7%Managed care and other discount plans19.1% 20.0% 19.4% 19.8%Other third-party payors2.0% 1.9% 1.8% 2.0%Patients1.4% 1.3% 1.4% 1.2%Other income1.5% 1.6% 1.5% 1.8%Total100.0% 100.0% 100.0% 100.0%We recognize net patient service revenues in the reporting period in which we perform the service based on our current billing rates (i.e., gross charges), less actual adjustments and estimated discounts for contractual allowances (principally for patients covered by Medicare, Medicaid, and managed care and other health plans). We record gross service charges in our accounting records on an accrual basis using our established rates for the type of service provided to the patient. We recognize an estimated contractual allowance to reduce gross patient charges to the amount we estimate we will actually realize for the service rendered based upon previously agreed to rates with a payor. Our patient accounting system calculates contractual allowances on a patient-by-patient basis based on the rates in effect for each primary third-party payor. Other factors that are considered and could further influence the level of our reserves include the patient’s total length of stay for in-house patients, each patient’s discharge destination, the proportion of patients with secondary insurance coverage and the level of reimbursement under that secondary coverage, and the amount of charges that will be disallowed by payors. Such additional factors are assumed to remain consistent with the experience for patients discharged in similar time periods for the same payor classes, and additional reserves are provided to account for these factors. Payors include federal and state agencies, including Medicare and Medicaid, managed care health plans, commercial insurance companies, employers, and patients.Management continually reviews the contractual estimation process to consider and incorporate updates to laws and regulations and the frequent changes in managed care contractual terms that result from contract renegotiations and renewals. Due to complexities involved in determining amounts ultimately due under reimbursement arrangements with third-party payors, which are often subject to interpretation, we may receive reimbursement for healthcare services authorized and provided that is different from our estimates, and such differences could be material. In addition, laws and regulations governing the Medicare and Medicaid programs are complex, subject to interpretation, and are routinely modified for provider reimbursement. All healthcare providers participating in the Medicare and Medicaid programs are required to meet certain financial reporting requirements. Federal regulations require submission of annual cost reports covering medical costs and expenses associated with the services provided by each hospital to program beneficiaries. Annual cost reports required under the Medicare and Medicaid programs are subject to routine audits, which may result in adjustments to the amounts ultimately determined to be due to HealthSouth under these reimbursement programs. These audits often require several years to reach the final determination of amounts earned under the programs. If actual results are not consistent with our assumptions and judgments, we may be exposed to gains or losses that could be material.The Centers for Medicare and Medicaid Services ("CMS") has been granted authority to suspend payments, in whole or in part, to Medicare providers if CMS possesses reliable information an overpayment, fraud, or willful misrepresentation exists. If CMS suspects payments are being made as the result of fraud or misrepresentation, CMS may suspend payment at any time without providing prior notice to us. The initial suspension period is limited to 180 days. However, the payment suspension period can be extended almost indefinitely if the matter is under investigation by the United States Department of Health and Human Services Office of Inspector General (the "HHS-OIG") or the United States Department of Justice. Therefore, we are unable to predict if or when we may be subject to a suspension of payments by the Medicare and/or Medicaid programs, the possible length of the suspension period, or the potential cash flow impact of a payment suspension. Any such suspension would adversely impact our financial position, results of operations, and cash flows.Allowance for Doubtful Accounts—We provide for accounts receivable that could become uncollectible by establishing an allowance to reduce the carrying value of such receivables to their estimated net realizable value. Additions to the allowance for doubtful accounts are made by means of the Provision for doubtful accounts. We write off uncollectible accounts (after exhausting collection efforts) against the allowance for doubtful accounts. Subsequent recoveries are recorded via the Provision for doubtful accounts.The collection of outstanding receivables from Medicare, managed care payors, other third-party payors, and patients is our primary source of cash and is critical to our operating performance. While it is our policy to verify insurance prior to a patient being admitted, there are various exceptions that can occur. Such exceptions include instances where we are (1) unable to obtain verification because the patient's insurance company was unable to be reached or contacted, (2) a determination is made that a patient may be eligible for benefits under various government programs, such as Medicaid, and it takes several days, weeks, or months before qualification for such benefits is confirmed or denied, and (3) the patient is transferred to our hospital from an acute care hospital without having access to a credit card, cash, or check to pay the applicable patient responsibility amounts (i.e., deductibles and co-payments). Based on our historical collection trends, our primary collection risks relate to patient accounts for which the patient was the primary payor or the primary insurance carrier has paid the amounts covered by the applicable agreement, but patient responsibility amounts remain outstanding. Changes in the economy, such as increased unemployment rates or periods of recession, can further exacerbate our ability to collect patient responsibility amounts.We estimate our allowance for doubtful accounts based on the aging of our accounts receivable, our historical collection experience for each type of payor, and other relevant factors so that the remaining receivables, net of allowances, are reflected at their estimated net realizable values. Accounts requiring collection efforts are reviewed via system-generated work queues that automatically stage (based on age and size of outstanding balance) accounts requiring collection efforts for patient account representatives. Collection efforts include contacting the applicable party (both in writing and by telephone), providing information (both financial and clinical) to allow for payment or to overturn payor decisions to deny payment, and arranging payment plans with self-pay patients, among other techniques. When we determine all in-house efforts have been exhausted or it is a more prudent use of resources, accounts may be turned over to a collection agency. Accounts are written off after all collection efforts (internal and external) have been exhausted.We have experienced denials of certain diagnosis codes by Medicare contractors based on medical necessity. We dispute, or "appeal," most of these denials, and we have historically collected approximately 58% of all amounts denied. The resolution of these disputes can take in excess of one year, and we cannot provide assurance as to our ongoing and future success of these disputes. As such, we make provisions against these receivables in accordance with our accounting policy that necessarily considers the age and historical collection trends of the receivables in this review process as part of our Provision for doubtful accounts. Because we do not write-off receivables until all collection efforts have been exhausted, we do not write-off receivables related to denied claims while they are in this review process. When the amount collected related to denied claims differs from the net amount previously recorded, these collection differences are recorded in the Provision for doubtful accounts. As a result, the timing of these denials by Medicare contractors and their subsequent collection can create volatility in our Provision for doubtful accounts.If actual results are not consistent with our assumptions and judgments, we may be exposed to gains or losses that could be material. Changes in general economic conditions, business office operations, payor mix, or trends in federal or state governmental and private employer healthcare coverage could affect our collection of accounts receivable, financial position, results of operations, and cash flows.Share-Based Payments—In February and May 2012, we issued 0.9 million and 0.2 million, respectively, of restricted stock awards to members of our management team and our board of directors. Approximately 0.6 million of these awards contain only a service condition, while the remainder contain both a service and a performance condition. For the awards that include a performance condition, the number of shares that will ultimately be granted to employees may vary based on the Company’s performance during the applicable two-year performance measurement period. Additionally, in February 2012, we granted 0.2 million stock options to members of our management team. The fair value of these awards and options was determined using the policies described in Note 1, Summary of Significant Accounting Policies, and Note 16, Share-Based Payments, to the consolidated financial statements accompanying the 2011 Form 10-K.We use the with-and-without method to determine when we will recognize excess tax benefits from stock-based compensation. Under this method, we recognize these excess tax benefits only after we fully realize the tax benefits of net operating losses. See Note 7, Income Taxes.Recent Accounting Pronouncements—In May 2011, the Financial Accounting Standards Board amended its guidance to clarify its intent about the application of existing fair value measurement and disclosure requirements. The primary impact to us resulted from additional disclosure requirements included in the amended guidance, including the requirements to categorize by level of the fair value hierarchy items not measured at fair value in our balance sheet but for which fair value is required to be disclosed. We adopted this guidance as of January 1, 2012. Our adoption of this standard primarily impacted our fair value disclosures related to our long-term debt and had no impact on our financial position, results of operations, or cash flows. See Note 6, Fair Value Measurements.See also the "Reclassifications" section of this note. Since the filing of the 2011 Form 10-K, we do not believe any other recently issued, but not yet effective, accounting standards will have a material effect on our consolidated financial position, results of operations, or cash flows. |
