Preserving Patient Access to Inpatient Rehabilitation Hospitals Act of 2007

Preserving Patient Access to Inpatient Rehabilitation Hospitals Act of 2007 - Amends the Deficit Reduction Act of 2005 to revise the classification criterion used to determine whether a hospital or hospital unit is an inpatient rehabilitation facility under title XVIII (Medicare) of the Social Security Act. Eliminates the current schedule of applicable percentages. Directs the Secretary of Health and Human Services, instead, to require in the classification criterion a compliance rate no greater than the 60% compliance rate that became effective for cost reporting periods beginning on or after July 1, 2005.

Requires the Secretary, for cost reporting periods beginning on or after July 1, 2007, to include patients with comorbidity in the inpatient population that counts towards such 60% compliance rate.

Requires the Secretary, the Centers for Medicare & Medicaid Services, fiscal intermediaries, Medicare administrative contractors, recovery audit contractors, and other government agents to use and apply the criteria established in HCFA Ruling 85-2, as issued on July 31, 1985, as the sole standard for determining the medical necessity of services provided by inpatient rehabilitation hospitals and units to beneficiaries under the Medicare program.
