Quarterly Addenda Updates

Quarterly Addenda Updates

Updates of Addendum A and B are posted quarterly to the OPPS website. These addenda are a "snapshot" of HCPCS codes and their status indicators, APC groups, and OPPS payment rates, that are in effect at the beginning of each quarter. The quarterly updates of Addendum A and Addendum B reflect the OPPS Pricer changes that are part of the quarterly OPPS recurring update notification transmittals.
