CMS Opens 340B Part D Claims Data Repository for Voluntary Use

CMS launched its 340B Part D claims data repository on October 1, allowing covered entities and third-party administrators to begin submitting claims data voluntarily. CMS has proposed requiring mandatory submissions starting January 1, 2027. To support entities during the transition, CMS has published a user guide, companion guide, fact sheet, and FAQ. The repository is intended to improve tracking of 340B drug claims under Medicare Part D.
