  • 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 through OneHealthPort’s ProviderSource. If you're unable to submit through ProviderSource, use our hard-copy credentialing application. Use our provider credentialing checklist to make sure you've submitted all necessary information.

    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.

    For dental and facility providers

    Dental provider application - Request to join our dental network
    Organization/facility credentialing/recredentialing application
    - Request to join our provider network as a facility

    All applicants need to email us at credentialing.updates@premera.com to tell us you’ve completed your credentialing application and remember to attach the following completed documents:

    • SS-4 IRS confirmation letter (displaying Employer Identification Number or EIN)
    • Behavioral health specialty addendum (behavioral health providers only)
    • Department of Health license approval letter (behavioral health providers only)

    You’ll receive a confirmation email from Premera that says we’ve received your request.

    How to avoid delays

    The top reasons for incomplete applications include:

    • Incomplete address, suite number, or phone number
    • Missing SS-4 (EIN) on new contracts
    • Expired malpractice insurance
    • Missing work history or education information
    • Hospital privileges, if applicable

    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.
