Is this NPI on the pending Medicare enrollment list?

Paste one NPI or a roster of up to 100. The checker reads the newest physician and non-physician pending files directly from CMS, validates each NPI, and returns a downloadable result.

Current public CMS files · up to 100 NPIs

Check a roster against the current pending list.

The browser downloads the two source CSVs directly from CMS and checks only the NPIs you paste. Nothing is uploaded to ActableSite.

What this result means—and what it does not.

On current listThe NPI appears in the dated public CMS Pending Initial Logging and Tracking physician or non-physician file.

Not foundThe NPI was not present in those two dated files. It may be approved, rejected, withdrawn, associated with another enrollment path, absent from the publication, or otherwise outside this checker.

Official application statusUse the PECOS application-status search or the responsible Medicare Administrative Contractor for the actual processing stage and requests for information.

Built for roster checks, not individual application management.

CMS already provides a free official application-status search for an individual provider or organization. This tool solves a different job: quickly compare a small credentialing, billing, or provider-operations roster with the two current public pending files and export the result.

The files can change between publications. Every check resolves the current source URLs from the self-refreshing edition receipt instead of relying on a hard-coded local copy.
