Third-Party Registration

Health Plans: 

  • NaviNet Basics


  • NaviNet Policies and Agreements

If you're a third party, such as a billing or credentialing agency, you must register for your own account with NaviNet.

If you're a third party and you want to sign up for AllPayer Access or Medicare Access, please call Provider Sales instead at 1-800-721-8563, and choose 3 for Billing.

Register as a third party with NaviNet

During the NaviNet registration process, provide your information. On the About Your Office page, choose the Billing Agency (Third party billing administrator) option to register and to view the requirements that apply to third parties only. Provide the tax IDs of the providers that you contract with, and download the required third-party authorization form.

If you're a third party, and you mistakenly registered as a provider instead, please register again as a third party, or contact NantHealth Support.   

Download a third-party authorization form

Include a Third-Party Authorization form (also called a Billing Agency Access Form or a Provider Entity Authorization Form) when you first register with NaviNet, and when you add tax IDs or health plans to your office.  

NaviNet no longer accepts Third-Party Authorization forms via fax or email

  1. Download the form. When you register and indicate that you are a billing agency, before you complete the registration we provide a link for you to download the authorization form. You can also download the Third-Party Authorization Form here.


  2. Complete the Third-Party Authorization Form for each of your requested tax IDs.  
  3. Provide the two required signatures. We don't accept electronic signatures.
    • One signature from a third-party employee.
