OPPS Drugs and Biologicals with Quarterly Restated Payment Rates

Some drugs and biologicals based on ASP methodology may have payment rates that are corrected retroactively. These retroactive corrections typically occur on a quarterly basis as a part of the OPPS payment system quarterly update change request. Beginning with the January 2015 OPPS payment system quarterly update change request, the list of drugs and biologicals with corrected payments rates, for a particular quarter, are accessible from the "Restated Drug and Biological Payment Rates" page.
