How providers can join an Aetna network

Doctors and other providers can join the Aetna Health Network to provide medical services to a growing number of members. Once accepted as part of the network, a doctor is then a network provider and people with the Aetna plan will prefer to use their services. This is a strong advantage if Aetna has many subscribers in your area.

Aetna is recognized as one of the country’s leaders in health insurance. With millions of members on its medical plan, Aetna still has a strong presence in most states. Use the steps below as a guide to joining an Aetna network.

Step 1: Get a National Provider ID (NPI)

Before applying for Aetna’s network, providers, including physicians, other clinicians, medical practitioners, and certain suppliers, must obtain an NPI.

The National Provider ID or NPI is a unique 10-digit identification number used to replace provider IDs, such as the Provider Unique Identifier (UPIN) in standard HIPAA transactions. Healthcare providers are required by HIPAA regulation to obtain an NPI.

If you do not already have an NPI, apply for one at or call your NPI Trainer at 1-800-465-3203.

Step 2: Submit an application

Aetna requires any provider that has an interest in joining an Aetna network to apply before joining. The application form is evaluated to determine the need for a participating provider in the geographical location of your medical office. Contact one of the following to submit your request for a doctor and other clinical professionals:

  1. Fill out the online medical plan application form on the Aetna website
  2. Contact a dealer at 1-800-353-1232
  3. The medical unit should contact the Aetna Customer Service Center at 1-888-632-3862.
