NPI Registry and NPI Lookup Tool

What is NPI (National Provider Identifier)?

The National Provider Identifier (NPI) is a unique 10-digit identification number assigned to healthcare providers in the United States by the Centers for Medicare & Medicaid Services (CMS). It is a standardized identifier used in all administrative and financial healthcare transactions under the Health Insurance Portability and Accountability Act (HIPAA).

Why is the NPI Important?

The NPI plays a crucial role in simplifying and streamlining electronic healthcare transactions. It ensures that providers are properly identified when:

  • Submitting claims to insurance companies
  • Verifying provider credentials
  • Coordinating care between multiple providers
  • Enrolling in Medicare or Medicaid

Without a valid NPI, providers cannot bill health plans or be reimbursed for their services.

Who Needs an NPI?

An NPI is required for:

  • Individual healthcare providers (e.g., doctors, nurses, dentists, physical therapists)
  • Organizations and group practices (e.g., hospitals, clinics, laboratories)

There are two types of NPIs:

  • Type 1 NPI – for individual healthcare professionals
  • Type 2 NPI – for healthcare organizations or group practices

How to Apply for an NPI

Healthcare providers can apply for an NPI through the National Plan and Provider Enumeration System (NPPES) at https://nppes.cms.hhs.gov/. The application is free and usually takes a few days to process.
