Enroll as a billing provider

Do I need to submit an enrollment application fee?

Yes. An application fee may be required to complete your enrollment in compliance with federal regulations under 42 CFR 455.460.

Effective June 1, 2016, Washington Apple Health (Medicaid) is implementing an application fee for institutional provider enrollment applications. Providers who are enrolled with Medicare and providers currently enrolled with Apple Health will not be affected. Providers who will be subject to the application fee will be notified by HCA when the fee is required.

The Center for Medicare & Medicaid Services sets the application fee annually.

The application fee for 2023 is $688.

The application fee for 2024 is $709.

You must send all required documentation noted above with signatures, if required. At the end of the application process, you will be given instructions for sending the necessary documents.

Once you have completed step one of the application you will be given a 14-digit application ID number. Write this number down in case you need to save and access your application at a later time. The online application has up to 18 steps. If you do not have time to complete it now you will need your application number to regain access.

Important! This is not the end of the online application. There are 16 additional steps. Click OK in the bottom right corner of the screen once you receive your application ID number to continue and complete your application.

How can I get back into my online enrollment application?

If you started an online enrollment but have not completed the required steps, you may track your enrollment application* by using your 14-digit application ID and the Social Security number (SSN) or Federal Employer Identification Number (FEIN) you entered in step one of your application. This allows you to complete the enrollment and submit it for review and approval.
