OPPS & ASC: CY 2027 Proposed Rule – Submit Comments by August 31

CMS issued the CY 2027 Hospital Outpatient Prospective Payment System (OPPS) and Ambulatory Surgical Center (ASC) Payment System proposed rule that proposes updates to Medicare payment policies and rates for hospital outpatient and ASC services.

See a summary of proposed provisions, including a request for information. Comments are due by August 31; see the proposed rule for details on how to submit them.


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.
