    Contract acceptance

    Your acceptance is based on application information and network requirements. Please be aware that the credentialing process typically takes 60 to 90 days. If your submitted application is complete and you're accepted, you'll receive a counter-signed contract and start date. For all Premera plans, you can't see members under the contract until you're officially credentialed. Also, your malpractice insurance must start before credentialing is complete.
