Checking an organization

Match the NPI to the exact location you will visit or bill; each location can have its own.
Confirm the business entity with the secretary of state.
Check the HHS-OIG exclusion list for the organization and its owners.
Verify each clinician you will see on their own record and with the state license search.

Common questions

Why does Medstar Medical Group II have 289 NPIs?

An organization may obtain more than one Type 2 NPI, for example for separate locations or units that bill on their own. Medstar Medical Group II's NPIs list practice locations in 72 cities.

Is an organization NPI a license?

No. An NPI identifies who bills. Facilities and the clinicians who work there are licensed separately by the state.

Source: CMS National Plan and Provider Enumeration System (NPPES), monthly file of Aug 9, 2026 (NPPES files on CMS.gov). An NPI identifies who bills; it is not a license.
