Code List updates for years 2022 and earlier were published in the Federal Register as an addendum to the annual Physician Fee Schedule final rule.īeginning with the Code List effective January 1, 2023, updates are published solely on this webpage. We update the Code List to conform to the most recent publications of CPT and HCPCS codes and to account for changes in Medicare coverage and payment policies. We maintain and annually update a List of Current Procedural Terminology (CPT)/Healthcare Common Procedure Coding System (HCPCS) Codes (the Code List), which identifies all the items and services included within certain designated health services (DHS) categories or that may qualify for certain exceptions.
