What Is an Independent Review Organization
An Independent Review Organization (IRO) is a state-licensed, third-party entity that re-evaluates your insurance company's denial of medical care. When your insurer denies a claim as not medically necessary, an IRO assigns qualified physicians in the relevant specialty to review your medical records, your doctor's rationale, and the denial reason. If the IRO agrees your treatment was medically necessary, the insurer must pay the claim and cover the service retroactively.
When You Can Use an IRO
You can request an IRO review after your insurer issues an Adverse Determination and you've exhausted your internal appeal. Most states require insurers to notify you of your IRO rights on your Explanation of Benefits (EOB). You typically have 60 to 180 days from the adverse determination to file, depending on your state's regulations.
IRO reviews apply specifically to medical necessity denials. If your claim was denied for reasons like out-of-network billing, coding errors, or lack of prior authorization, an IRO cannot override that decision. However, if your insurer denied External Review eligibility or dragged out the internal appeal process, some states allow expedited IRO review.
How the IRO Process Works
- You submit a request: File a written request with your IRO (your insurer provides contact information). Include your EOB, medical records, your doctor's clinical notes, and a brief explanation of why you believe the denial was wrong.
- IRO assigns reviewers: The IRO selects physicians licensed in your state and board-certified in the relevant specialty. They cannot work for your insurance company or have financial ties to it.
- Reviewers examine evidence: The panel reviews clinical guidelines, peer-reviewed literature, and your specific medical circumstances. This typically takes 30 to 45 days for routine reviews or 3 to 5 business days for expedited urgent care reviews.
- IRO issues a decision: The IRO sends a binding determination to both you and your insurer. If the reviewers find your treatment was medically necessary, your claim is overturned and the insurer must pay.
Key Practical Points
- IRO decisions are binding on insurers in most states, though a handful of states allow limited insurer appeals to state insurance commissioners.
- You typically pay nothing for an IRO review. The insurer covers the cost, which averages $300 to $600 per case.
- IRO reviewers focus on whether treatment was medically necessary based on evidence at the time of denial, not whether it was the cheapest option.
- Different states regulate IROs differently. New York, California, and Texas have the most active IRO programs due to higher claim volumes and state mandates.
- If an IRO reverses your denial, ask your insurer for written confirmation of payment and any applicable refunds if you paid out of pocket.
Common Questions
- What happens if I disagree with the IRO's decision? IRO decisions are legally binding. Your only option is to file a formal complaint with your state insurance commissioner if you believe the IRO process violated regulatory requirements or if reviewers failed to consider submitted evidence.
- Can I request a specific type of doctor to review my case? No. The IRO selects reviewers based on specialty match and conflict-of-interest screening. You can, however, submit a list of relevant medical literature or expert opinions for reviewers to consider in their decision.
- How long does an IRO review actually take? Standard reviews take 30 to 45 days. If your treatment is urgent and ongoing, you can request an expedited review that typically produces a decision within 3 to 5 business days, but expedited reviews are only available for urgent conditions.
