CMS Releases Final Inpatient Rehabilitation Facility Payment Rule for 2008
On July 31, 2007, the Centers for Medicare & Medicaid Services (CMS) released a display copy of the Final Rule updating the payment rates and modifying the policies of the inpatient rehabilitation facility prospective payment system (PPS) for fiscal year (FY) 2008.
In the Final Rule, CMS increases inpatient rehabilitation facilities (IRF) payments by 3.2 percent, based on the rehabilitation, psychiatric and long-term care hospital market basket. The Final Rule also increases the high cost outlier threshold to $7,362 (from $5,534 in FY 2007), which means that fewer cases are expected to qualify for outlier payments in 2008. However, the Final Rule clarifies existing policy to indicate that short stay transfer cases that meet the criteria to qualify for outlier payments will be eligible to receive the additional payments.
The Final Rule also updates the IRF PPS wage index by establishing a policy in which the average wage index from all contiguous counties may be used in the future as a reasonable proxy for the rural area within a state. However, CMS reports that the Final Rule does not revise the current policy on the 75 percent rule. The 75 percent rule is used by CMS to classify a provider as an IRF. Currently, in addition to a patient's principal diagnosis, a patient's comorbidities may be used to determine whether a provider satisfies the 75 percent rule. However, for cost reporting periods beginning on or after July 1, 2008, comorbidities can no longer be used.
The Final Rule is expected to be published in the Federal Register on August 7, 2007.
