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.
Update: Effective June 1, 2018, Washington House Bill 2335 will require all insurance carriers to use ProviderSource. The bill will also require providers to submit credentialing applications using OneHealthPort's secure login. Also effective June 1, Premera must approve or deny the complete application no later than 90 days after receipt. A complete application is one that is not missing any information. This requirement changes to 60 days on June 1, 2020.
