      Is your application complete?

      Incomplete applications or missing information delays account set up and payment of services to you.

      To ensure timely processing, use the Medical Provider Network Credentialing Checklist (F245-445-000) to identify missing information.

      What to expect from L&I

      To process complete applications, allow 120 days. If additional information is needed to process your application, we will contact you.

      You will receive a letter in the mail once your application is processed.

      What is my application or network status?

      Having a provider account number or reactivating a closed account does not mean you are in our network. If you do not see that you are a network provider and want to treat an injured worker for ongoing care, you must apply.

      To check your application or network status, search by:

      L&I provider number or National Practitioner Identification (NPI) number

      What happens if I don't join?

      If you treat an injured worker for ongoing care, beyond the initial visit to file the Report of Accident form, you must be an approved network provider to be paid for services. Please refer the injured worker to a network provider.

      Find a network provider for patients that need ongoing care.
