Insurance Appeal Rights by State
Your appeal rights depend heavily on where you live and what type of plan you have. Some states have strong consumer protections with independent external review, binding decisions, and free Consumer Assistance Programs. Others defer to federal minimums. Below is what you need to know.
The Critical Distinction: State Law vs. ERISA
If your health insurance is through a large employer that self-funds its plan (the employer pays claims directly, using the insurer only to administer the plan), your appeal rights are governed by federal ERISA law, not state law. This means your state's consumer protections may not apply. ERISA provides a baseline: one level of internal appeal and access to federal external review, but not the enhanced protections some states offer.
If you have an individual plan, a marketplace plan, a small employer fully-insured plan, or a government plan, state law typically governs your appeal rights. ClearCost Appeals automatically determines which framework applies based on your plan information.
States with the Strongest Protections Enhanced
These states go beyond federal requirements and provide additional protections for insurance consumers. If you live in one of these states and have a state-regulated plan, you have significant leverage in your appeal.
New York
New York has some of the strongest insurance consumer protections in the country. The state requires insurers to provide a robust internal appeal process and offers a fully independent external review through the Department of Financial Services. Key features:
- External review decisions are binding on the insurer -- they must comply
- External review is available for medical necessity denials, experimental treatment denials, and out-of-network denials
- Expedited external review available within 72 hours for urgent cases
- Consumer Assistance Program provides free help navigating the appeal process
- Insurers must provide denial notices in plain language with specific reasons
- The external review fee is $25, refunded if the decision is overturned
California
California's Department of Managed Health Care (DMHC) and Department of Insurance (CDI) provide strong oversight. California was one of the first states to mandate independent external review.
- Independent Medical Review (IMR) through DMHC is free and binding on the insurer
- IMR overturn rate is approximately 60% -- one of the highest in the nation
- Expedited review available for urgent cases
- Robust Consumer Assistance program (Health Consumer Alliance)
- Strong network adequacy requirements -- if no in-network provider is available within a reasonable distance, the insurer must cover OON care
- Timely access requirements: insurers must provide appointments within specific timeframes
Illinois
Illinois provides strong protections including an external review process administered by the Department of Insurance.
- External review available for medical necessity and experimental treatment denials
- External review decisions are binding on the insurer
- No fee for external review
- Strong surprise billing protections (predating the federal No Surprises Act)
- Consumer Assistance Program through the Department of Insurance
Massachusetts
Massachusetts has a well-established external review program and strong consumer protections.
- External review through the Office of Patient Protection
- Decisions are binding on the insurer
- No cost to the consumer for external review
- Consumer Assistance available through the Health Policy Commission
- Strong mental health parity enforcement
States Using Federal External Review Process Federal Standard
These states either have not established their own external review process that meets federal standards or have opted to use the federal process. The federal external review process provides a baseline level of protection under the ACA, but does not include some of the enhanced features found in states with their own programs.
Under the federal process:
- External review is available for medical necessity and rescission disputes
- The review is conducted by an accredited Independent Review Organization (IRO)
- The IRO's decision is binding on the insurer
- The process is free to the consumer (or costs no more than $25, refundable if overturned)
- Standard reviews must be completed within 45 days; expedited reviews within 72 hours
Texas-Specific Note
Texas uses the federal external review process for fully-insured plans but has its own Independent Review Organization process administered by the Texas Department of Insurance for HMO plans. Texas also has a Consumer Assistance Program. If you are in Texas, the appeal process depends on whether you have an HMO or PPO/EPO plan.
Florida-Specific Note
Florida uses the federal external review process and does not have a state Consumer Assistance Program. However, the Florida Office of Insurance Regulation does accept consumer complaints and can investigate insurer practices. For HMO plans, the Agency for Health Care Administration (AHCA) handles grievances.
States with Consumer Assistance Programs (CAPs)
Consumer Assistance Programs provide free help from trained staff who can guide you through the appeal process, contact your insurer on your behalf, and sometimes advocate directly for you. If your state has a CAP, use it -- they are free and can significantly improve your chances.

Key Variations That Affect Your Appeal
Appeal Deadlines
The time you have to file an appeal varies significantly:
- Federal minimum (ERISA/ACA): 180 days for internal appeal
- Some insurers set shorter deadlines -- UnitedHealthcare allows only 65 days for post-service claims
- External review: Typically 4 months (120 days) after exhausting internal appeals under federal rules; some states allow longer
- Medicare Advantage: Only 60 days for internal appeal, but faster decision required (30 days standard, 72 hours expedited)
External Review Availability
External review is the most powerful tool in your arsenal because the decision is binding on the insurer. It is available for:
- Medical necessity denials (all states)
- Experimental or investigational treatment denials (all states)
- Rescissions (cancellation of coverage) (all states)
- Some states also allow external review for benefit interpretation disputes, not just clinical decisions
Surprise Billing Protections
The federal No Surprises Act (2022) provides a baseline, but several states have additional protections:
- New York, California, Colorado, Oregon -- had surprise billing laws before the federal act, some with stronger protections
- Texas -- strong mediation process for out-of-network billing disputes
- The federal law applies to emergency services, air ambulance, and services at in-network facilities by OON providers
Mental Health Parity
The federal Mental Health Parity and Addiction Equity Act requires that mental health benefits be comparable to medical benefits. But enforcement varies dramatically by state:
- Strong enforcement: NY, CA, IL, MA, CT, OR -- these states actively audit insurers for parity compliance
- Weaker enforcement: States without dedicated parity enforcement programs may require you to file a complaint to trigger a review
- If your mental health claim was denied with stricter criteria than would apply to a comparable medical claim, that is a parity violation
