The Healthcare Providers Verify skill validates practitioner credentials and license status against the NPI registry. It cross-references specialties, credentials, and practice addresses against official records and returns a verification status per provider. Powered by the Nimble CLI and built on the open-source Agent Skills standard for cross-platform agent compatibility.

How It Works

1

Parse input data

Accepts CSV, Google Sheet URL, pasted data, or output from the Extract or Enrich skills. Minimum input: provider name plus one of credentials, state, or specialty.
2

Look up NPI registry

Queries the NPPES API for each provider. Falls back to web search on npidb.org or nppes.cms.hhs.gov if the API returns no match.
3

Cross-reference and verify

Matches provider data against NPI records across four dimensions: name, credentials, taxonomy (specialty), and address.
4

Flag discrepancies

Identifies critical issues (deactivated NPI, credential mismatch, specialty mismatch) versus warnings (address differences, stale records, name variants).
5

Deliver verification report

Outputs a per-provider verification status with detailed match results and source links.
