- The Centers for Medicare & Medicaid Services (CMS) has once again delayed the long-awaited release of the National Provider Identifier (NPI) database. You-ll be able to look up NPIs for referring physicians starting Sept. 4 and the downloadable file will be available about a week later, CMS says in a message to providers.
CMS is allowing the extra time to allow providers to edit their own National Plan and Provider Enumeration System (NPPES) data that will be in the database, CMS maintains. Providers have until Aug. 20 to submit their data edits.
