State External Review Rights: All 50 States Guide
Every state's external review rights explained: ACA requirements, state vs. federal programs, IRO process, deadlines, and how to request an independent medical review.
If your health insurance claim has been denied and your internal appeal failed, you may have one more powerful option: External Independent Review: Complete Guide" class="auto-link">external review. An IROs) Explained" class="auto-link">Independent Review Organization (IRO) — staffed by physicians with no connection to your insurer — reviews your case and issues a decision that is legally binding on your health plan. This guide explains how external review works, the difference between state and federal programs, and what your rights are in every state.
What Is External Review?
External review is a process by which an independent medical organization — not your insurance company — evaluates whether your insurer's denial of a claim was correct. The review is conducted by licensed physicians with relevant clinical expertise who assess whether the denial was clinically appropriate and consistent with your plan's terms.
The key features:
- Independent: The reviewers have no financial relationship with your insurer
- Binding: If the IRO overturns the denial, your insurer must cover the service — by law
- Free: Consumers pay nothing; insurers pay the IRO fees
- Fast: Standard reviews complete in 45 days; urgent reviews in 72 hours or less
The ACA External Review Requirement
The Affordable Care Act (ACA) requires all non-grandfathered health plans to provide external review rights. Plans issued on or after September 23, 2010 must comply. Grandfathered plans (those in existence before the ACA that have not made significant changes) are generally exempt.
What the ACA covers:
- Medical necessity denials
- Denials of experimental or investigational treatments
- Rescissions of coverage (retroactive cancellations)
- Adverse benefit determinations that have exhausted internal appeals
What external review does NOT cover:
- Coverage disputes (whether something is excluded from the plan at all)
- Billing disputes (incorrect amounts charged)
- Network disputes in some states
- Self-funded ERISA plans (in most cases — see below)
State Programs vs. Federal Program
The ACA allows states to operate their own external review programs if they meet federal minimum standards. States that run their own programs are called "accredited states." States that don't meet federal standards use the HHS-administered federal external review program.
Accredited state programs generally offer equivalent or stronger protections than the federal minimum. States like California (DMHC), New York (DFS), and Washington (OIC) have well-established programs.
The federal program applies in states that did not establish qualifying programs or for self-funded plans that choose to participate. Under the federal program, HHS designates multiple IROs and randomly assigns cases. The same binding, free, and timely standards apply.
The 4-Month Deadline
Regardless of whether you're using a state or federal program, the deadline to request external review is 4 months (approximately 120 days) from the date of the final adverse determination. This is the final denial from your insurer — either the denial of your internal appeal or the original denial if no appeal was pursued.

How to Request External Review: Step-by-Step
- Exhaust internal appeals: In most cases you must complete your insurer's internal appeal process first. Your insurer's final denial letter will include information about external review rights — this is legally required.
- Identify your program: Check whether your state runs its own program or uses the federal program. Contact your state insurance department or call 1-888-393-2789 (the federal external review hotline).
- Submit your request: File your external review request with the appropriate agency. Provide your denial letter, medical records, physician support letters, and a written request for review.
- Wait for IRO assignment: The relevant authority assigns your case to an independent IRO. You'll be notified of the assignment.
- IRO reviews your case: The IRO requests records from your insurer and may contact your physician. Standard review is within 45 days; expedited within 72 hours.
- Receive the decision: The IRO issues a written decision. If they overturn the denial, your insurer must cover the service.
Expedited (Urgent) External Review
If the denied treatment is urgently needed — meaning that waiting for a standard review would seriously jeopardize your health or your ability to regain maximum function — you can request expedited external review. Expedited reviews must be completed within:
- 72 hours for most state and federal programs
- 3 business days in some state programs
Request expedited review if:
- Your condition could deteriorate significantly without treatment
- You are currently hospitalized
- The denied care is time-sensitive (pre-surgery approval, ongoing cancer treatment, etc.)

Self-Funded Plans and External Review
Here is a critical limitation: most self-funded ERISA plans are not subject to state external review requirements. Because ERISA preempts state insurance law for self-funded plans, the state programs above generally do not apply.
However, there are important exceptions:
- Voluntary participation: Some self-funded plan sponsors voluntarily participate in external review programs
- Federal external review for non-grandfathered self-funded plans: The ACA extended federal external review rights to non-grandfathered self-funded plans. These plans must provide external review through IROs designated by HHS.
- Government plans: Many federal and state government employee plans have their own external review processes
If you're unsure whether your self-funded plan has external review rights, contact your plan administrator or the U.S. Department of Labor's Employee Benefits Security Administration (EBSA) at 1-866-444-3272.
What Happens If the IRO Rules Against You?
If the IRO upholds the denial, the denial stands. The IRO's decision is binding on both sides. However, you may still have legal options if you believe the denial violated your plan terms or applicable law:
- Consult an ERISA attorney: For self-funded plans, you may be able to bring a civil action under ERISA Section 502(a)
- State court claims: For state-regulated plans, you may be able to pursue breach of contract or bad faith claims in state court
- File a regulatory complaint: Even after external review, you can file a complaint with your state insurance department for regulatory investigation
Tips for a Successful External Review
- Get your physician's support: The most successful external reviews include a detailed letter from your treating physician explaining the clinical basis for the denied treatment. Include peer-reviewed literature if available.
- Submit all records promptly: IROs work on tight timelines. When they request records, respond immediately to avoid delays.
- Request expedited review for urgent situations: If waiting would jeopardize your health, make the urgency clear in your request.
- File before the 4-month deadline: The clock starts ticking on your final denial date — not when you became aware of it.
- Know your plan type: State programs cover fully-insured plans. Self-funded plans follow federal rules. Confirm your plan type before filing.
