Washington Medicaid, revalidated and paid

At the direction of the Centers for Medicare and Medicaid Services, the Washington State Health Care Authority (HCA) and the Department of Social and Health Services will finish off cycle revalidations for certain providers by June 5, 2028, with notices by email or mail to those selected. HCA announced the plan on August 26, 2026 in its off cycle revalidation announcement.

How Washington enrollment and revalidation work, step by step

1. Wait for the notice, and confirm the mailing and email addresses on file. For a standard revalidation, no action is required until the revalidation letter arrives, and it goes to the mailing address on file.

2. Count 30 days. A provider has 30 days from the date on the notice before a deactivation notice is sent, then an additional 90 days. Washington Health Care Authority revalidation page
3. Billing providers send the signed forms. That means a signed Core Provider Agreement and Debarment Statement, plus the Internal Revenue Service tax form for the provider. Washington Health Care Authority revalidation page
4. Update ownership disclosures. Updated disclosures of ownership, managing employees and other controlling interests must be submitted when the information on file is reviewed and updated. Washington Health Care Authority revalidation page
5. Nonbilling providers use the support portal or fax. Nonbilling providers submit required documents through the HCA support portal or by fax. Washington Health Care Authority revalidation page

A provider that serves clients under both managed care and fee for service is a billing provider and follows the billing provider steps.

All billing providers must complete and sign a Core Provider Agreement and other required documents, and a health care professional practicing under a group or facility needs that group or facility enrolled with HCA first.
