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.

Washington Apple Health (Medicaid) requires 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 2024 is $709.

If you do not have time to complete it now you will need your application number to regain access.

Note: If you choose to use your Social Security number (SSN) as your tax ID you will need to update the servicing type to “Regular Individual Provider." Additionally, individual NPI type must be used for this enrollment.

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.
