How to file an external review in Arizona
Arizona runs its own external review program through the Department of Insurance and Financial Institutions (DIFI), not the federal HHS process. After your insurer issues its final internal appeal denial, you have four months to request an external independent review. You start by filing with your insurer, which forwards the case to DIFI; the DIFI director then assigns an independent review organization (IRO). For contract or coverage disputes the IRO decides within about 21 days, while standard medical-necessity decisions generally reach you within roughly 30 days of your request. Urgent matters qualify for expedited review, with a decision generally within 72 hours. The IRO's determination is binding on the insurer, which must cover the service or pay the claim without delay, and the review is provided at no cost to you.
Arizona appeal questions
How do I file an external review in Arizona after my health insurance appeal is denied?
In Arizona you must first exhaust your insurer's internal appeal levels, then request an external independent review through the Department of Insurance and Financial Institutions (DIFI). You submit the request to your health insurer, which is required to forward your case and records to DIFI, and the DIFI director assigns an independent review organization to decide it. You can also contact DIFI Consumer Services for help with the process.
What is the deadline to request external review in Arizona?
You generally have four months after your insurer notifies you that your formal internal appeal was denied to request an external independent review. Missing that window can forfeit your right to this review, so act promptly once you receive the final denial. If your situation is urgent, you may qualify for expedited review without waiting for every internal level to finish.
Does an external independent review in Arizona cost anything?
No. The external independent review through DIFI is provided at no cost to you as the member. The independent review organization's fees are not charged to the patient. You are responsible only for your own expenses, such as gathering medical records or obtaining a supporting letter from your treating provider.
Is the Arizona external review decision binding, and does it apply to my self-funded employer plan?
Yes. If the independent review organization finds the service covered and medically necessary, your insurer must provide it or pay the claim without delay, and that decision is binding on the insurer. However, many large-employer plans are self-funded under federal ERISA law and fall outside Arizona's state program; those plans follow the federal external review process instead. Check whether your plan is fully insured or self-funded to confirm which path applies.
