FAQ

Questions CMS.gov Data owners ask.

  • 01

    Do I need an API key to use this server?

    No. The CMS.gov Provider Data API is completely public and requires no authentication. Simply subscribe to this server to start querying Medicare provider data, hospital ratings, and open datasets immediately.

  • 02

    How current is the data?

    CMS updates the Provider Data Catalog periodically, typically on a quarterly or monthly basis depending on the dataset. Hospital quality ratings are updated annually through the Hospital Compare program. All data is sourced directly from the official CMS.gov open data APIs.

  • 03

    What is an NPI number?

    The National Provider Identifier (NPI) is a unique 10-digit identification number issued by CMS to every US healthcare provider. It's the universal standard for identifying doctors, hospitals, and healthcare organizations in Medicare and Medicaid transactions. You can search for any provider by their NPI using this server.
