On August 7, 2007, the Centers for Medicare & Medicaid Services (CMS) published the Final Rule in the Federal Register, updating the payment rates and modifying the policies of the inpatient rehabilitation facility (IRF) prospective payment system (PPS) for fiscal year (FY) 2008. However, the Final Rule does not revise the current Medicare policy on the 75 percent compliance threshold (75 percent rule).
In order to be excluded from the inpatient hospital PPS and paid under IRF PPS, a hospital or hospital unit must meet the requirements for classification as an IRF. One criterion that CMS has used for classifying a hospital or hospital unit as an IRF is that a minimum percentage of a facility’s total inpatient population require intensive rehabilitative services for the treatment of at least 1 of 13 medical conditions. This minimum percentage is known as the “compliance threshold.”
Prior to May 7, 2004, the compliance threshold was 75 percent. However, in a May 7, 2004 final rule, CMS lowered the compliance threshold, and established a transition period in which IRFs would have to satisfy the 75 percent rule starting on or after July 1, 2007. CMS also specified that, during the transition period, a patient’s comorbidity could be used to determine whether the compliance threshold was met.
The Deficit Reduction Act of 2005 (DRA) extended the compliance threshold transition period. Under the DRA, the transition period was extended to include cost reporting periods starting on or after July 1, 2004 and before July 1, 2008. Therefore, Medicare regulations were revised requiring that an IRF meet the 75 percent rule as of its first cost reporting period that starts on or after July 1, 2008. For cost reporting periods beginning before July 1, 2008, CMS also continued the use of a patient’s comorbidity when making compliance threshold determinations. However, for cost reporting periods beginning on or after July 1, 2008, current Medicare policy will not consider a patient’s comorbidities when determining whether a provider meets the 75 percent rule.
In the proposed IRF PPS rule for FY 2008, CMS solicited comments regarding current Medicare policy and other options (including the use of some or all of the existing comorbidities for an additional fixed period and the inclusion of some or all of the existing comorbidities on a permanent basis). However, in the Final Rule, CMS indicates that it will maintain the current Medicare policy. Therefore, for cost reporting periods beginning on or after July 1, 2007 and before July 1, 2008, the compliance threshold will remain at 65 percent and comorbidities can be used when calculating the compliance threshold. However, for cost reporting periods beginning on or after July 1, 2008, comorbidities may not be used to determine whether the 75 percent rule has been met.
