How to apply

Before applying, check the Washington network closure matrix to see which counties are open to accepting new providers.

Request an individual contract or join one of our contracted independent practice associations or medical groups. In either case, you must meet our credentialing standards and criteria.

Submit your credentialing application using Medversant's ProviderSource. You'll need your OneHealthPort subscriber ID and password. Access to ProviderSource ends on December 31, 2023. Starting January 1, 2024, you can submit your application using our hard-copy credentialing application while we transition to a new vendor. Find out more about the new credentialing vendor.

Use our provider credentialing checklist to make sure you've submitted all necessary information.

Submit your credentialing application via the following options:

• Fax: 425-918-4766
• Email: credentialing.updates@premera.com
• Mail: PO Box 327 – MS 263, Seattle, WA 98111-0327

After completing your credentialing application through ProviderSource, check the application box indicating that you’re applying for participation with Premera. Important: Make sure the attestation date on your provider application is within 150 days from when you submit your application.

• Behavioral health specialty addendum (behavioral health providers only)

What happens next

The credentialing process typically takes 30-45 days and acceptance is based on your application information and network requirements. If your submitted application is accepted:

• New provider joining our network: You'll receive a contract to review and sign through DocuSign. Once you return your signed contract, you'll receive a counter-signed contract through DocuSign with your participation effective date.
• New provider joining an existing contracted group/clinic: You’ll receive a letter with your credentialed date, and you’ll be added under the group/clinic’s location(s) as a credentialed provider.

For all Premera plans, you can't see members until you're officially credentialed under contract. Also, your malpractice insurance must not expire before credentialing is complete.

Request a copy of your contract

If you need a copy of your contract, send us an email request and we’ll send it to you directly as an email attachment. Please note this email is only for requesting contract copies.
