How to file an external review in Montana
Montana runs its own external review program through the Office of the Montana State Auditor, Commissioner of Securities and Insurance. After your insurer's final internal denial, you have 120 days to file a written request for external review with the health insurer, which then forwards eligible cases to an independent review organization assigned from the Commissioner's approved IRO list (under Montana Code Annotated Title 33, Chapter 32, Part 4). A standard review must finish within 45 days, and an expedited review for urgent or serious situations is decided within 72 hours. The IRO's decision is binding on the insurer, and the review is free to you. Note that the carrier must include external review instructions in its final denial notice.
Montana appeal questions
How do I file an external review in Montana?
Within 120 days of your insurer's final internal denial, submit a written external review request to your health insurance company. Montana's program is overseen by the Commissioner of Securities and Insurance (the State Auditor's Office), and the insurer assigns your case to an approved independent review organization from the Commissioner's list. Your final denial letter should include the specific instructions and form for requesting review.
What is the deadline to request external review in Montana?
You generally have 120 days from the date you receive the final adverse determination to file your request, under Montana Code Annotated Title 33, Chapter 32, Part 4. Missing this window can forfeit your right to external review, so file promptly. If your situation is urgent, you can request an expedited review without first exhausting every internal step.
Does external review cost anything in Montana, and how long does it take?
The external review is free to you as the patient; the cost is borne by the insurer. A standard review must be completed within 45 days of the IRO receiving the case. An expedited review, available when delay would seriously jeopardize your health or ability to regain function, is decided within 72 hours.
Is the decision binding, and what if my plan is self-funded through my employer?
Yes. The independent review organization's decision is binding on the insurer, so if the IRO overturns the denial, the carrier must cover the service. However, many large-employer self-funded plans are governed by federal ERISA law and may use the federal HHS-administered external review process instead of Montana's program. Check your plan documents or denial letter to confirm which path applies to you.
