The Department of Defense (DoD) has published a notice that it is proceeding with implementation of its December 10, 2008 final rule establishing a prospective payment system (PPS) for TRICARE hospital outpatient services, similar to the Medicare hospital outpatient PPS (OPPS). The effective date had been extended from February 9, 2009 until May 1, 2009 as part of the Obama Administration’s broader regulatory review. After review of public comments, the DoD is making no changes to the final rule and the effective date continues to be May 1, 2009.
