Quarterly HCPCS Changes

CMS updates HCPCS Level II codes quarterly — new codes added, existing codes revised, and discontinued codes deleted.

Medical billers and coding teams must track these updates to avoid miscoding claims. Using a deleted code may trigger an automatic denial; missing a new code can mean lost revenue or forcing a workaround with an incorrect code. CMS typically releases quarterly updates in advance to give providers time to update their chargemasters, practice management systems, and claim scrubbers before the effective date.

Quarterly change data will be available after the ETL run.
