What is the Difference Between an Individual NPI and a Group NPI?

The National Provider Identifier (NPI) is a 10-digit, unique identification number issued by the Centers for Medicare & Medicaid Services (CMS) to health care providers in the United States. There are two main types of NPIs:

Type 1 – Individual NPI

Type 2 – Organizational or Group NPI

Understanding the difference between the two is essential for correctly submitting claims and registering healthcare providers with payers.

Type 1 – Individual NPI

A Type 1 NPI is issued to individual healthcare providers, such as:

  • Physicians

  • Nurse Practitioners

  • Therapists

  • Chiropractors

  • Dentists

Each individual provider is required to have their own NPI, even if they work for a group or facility. This NPI is assigned to a person, not a business, and is used to identify the rendering provider on insurance claims.

Example:
Dr. Sarah Johnson, a family medicine physician, works for Oakwood Medical Group. Dr. Johnson must use her Type 1 NPI when she provides services and is listed as the rendering provider on claims.


Type 2 – Group or Organizational NPI

A Type 2 NPI is issued to healthcare organizations, such as:

  • Group practices

  • Hospitals

  • Laboratories

  • Ambulatory surgical centers

  • Home health agencies

This NPI is assigned to the business entity and used to identify the billing provider on insurance claims. If your practice is set up as a group (e.g., an LLC or corporation), the business will need a Type 2 NPI—even if there is only one provider in the group.

Example:
Oakwood Medical Group, where Dr. Johnson works, has a Type 2 NPI. This number is used as the billing provider on claims submitted to insurance companies.


When Both Are Required

Most insurance claims require both NPIs:

  • Rendering Provider NPI (Type 1): The individual who provided the service

  • Billing Provider NPI (Type 2): The group or entity submitting the claim and receiving payment

In Dr. Johnson’s case, her individual Type 1 NPI will be listed as the rendering provider, while Oakwood Medical Group’s Type 2 NPI will be the billing provider.


Notes

Key Takeaways

  • All individual health care providers need a Type 1 NPI, even if they work in a group setting.

  • Any group practice or organization that submits insurance claims must obtain a Type 2 NPI.

  • Both NPIs are often used together on claims: Type 1 for the person providing the care, and Type 2 for the entity billing for the care.

  • NPIs never expire and are not reassigned. Each provider and organization retains the same NPI for life.
