Hospital-based and freestanding skilled nursing facilities: any cause for differential Medicare payments?

Differential Medicare payments for hospital-based and freestanding skilled nursing facilities (SNFs) were eliminated by the SNF prospective payment system initiated in 1998. Closures and high negative margins of hospital-based facilities have prompted consideration of the need to revisit payment adjustments for this group of SNFs. We examine case mix-related and other factors behind the cost differences between hospital-based and freestanding SNFs. Some payment adjustment, notably for nontherapy ancillary services, may be reasonable for the short term.
