Quarterly HCPCS Changes

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

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.
