The U.S. Health Care Financing Administration (HCFA) is delaying implementation of new regulations governing which hospital sites and departments are permitted to be reimbursed as hospital-based. The provider-based regulations, promulgated as part of the Outpatient Prospective Payment System, were to have been effective on October 10, 2000, but due to the number of questions raised about their scope and how they would be applied, HCFA will delay effectiveness until January 10, 2001. The requirements for coming into compliance with the regulations will be phased in over a 12-month period, with some hospitals affected in 2001 and some affected as of 2002. GNYHA will continue to work with HCFA to address issues of most concern to member institutions.
