How to file an external review in Washington
Washington runs its own external review program through the Office of the Insurance Commissioner (OIC), not the federal HHS process. After you exhaust your health plan's internal grievance and receive a final denial, you can request independent review by a certified Independent Review Organization (IRO). Once you request it, the carrier assigns an IRO from the OIC's rotational registry, and standard reviews are typically completed within about 20 days of the IRO receiving your request. Urgent situations qualify for expedited review, decided within 72 hours. By statute (RCW 48.43.535), the carrier must implement the IRO's determination and pay the IRO's charges, so the decision is binding and free to you. Request review promptly after your final denial; ask the OIC if you are unsure of your filing window.
Washington appeal questions
How do I request an external review (IRO) in Washington after my appeal is denied?
First finish your health plan's internal appeal process and get a final written denial. Then ask for independent review, and your carrier will assign a certified Independent Review Organization from the Office of the Insurance Commissioner's rotational registry. If you need help starting this, the OIC consumer advocacy line at 1-800-562-6900 can walk you through it.
Is there a deadline to request independent review in Washington?
You should request independent review promptly after you receive your plan's final internal denial, since waiting too long can put your right to review at risk. Washington's statute focuses on the steps that follow your request, so if you are unsure how long you have, confirm your specific window with the OIC's consumer advocacy line. If your situation is urgent and your health is at serious risk, you can ask for an expedited review right away.
Does an independent review in Washington cost me anything, and is the decision binding?
It is free to you. Under RCW 48.43.535, the insurer pays the IRO's charges, not the patient. The IRO's determination is binding on your health plan, meaning if the reviewer overturns the denial, your carrier must implement that decision and cover the disputed care.
What if my plan is a self-funded employer (ERISA) plan in Washington?
Self-funded employer plans are governed by federal ERISA law and are not treated as health plans under Washington state law, so the OIC's IRO process may not apply to them. These plans usually follow the federal external review process administered through the U.S. Department of Health and Human Services or a private IRO. Check your plan documents or denial letter to confirm which external review path covers you.
