Internal Medicine physicians (internists) specialise in the prevention, diagnosis, and treatment of diseases in adults, often coordinating care across multiple subspecialties.
Every NPI shown on FindMyNPI is sourced directly from the CMS NPPES public registry and validated via the Luhn check-digit algorithm. Click any provider's "View NPI" button to see the full verified record. The data is updated monthly from the federal source.
A Type-1 NPI (NPI-1) is issued to an individual healthcare provider for life, and tracks them across employers and locations. A Type-2 NPI (NPI-2) is issued to an organisation such as a hospital, clinic, or group practice. Many providers will have both: their personal Type-1 plus a Type-2 for their practice entity.
The NPPES registry does not include commercial insurance network data, so we cannot show which plans a provider accepts. Contact the provider's office directly using the phone number on their profile to confirm in-network status with your specific health plan.
