If you get health insurance through your employer, your plan is almost certainly governed by the Employee Retirement Income Security Act of 1974 (ERISA). ERISA creates a specific legal framework for health benefit appeals that is different — in important ways — from state insurance regulations. Understanding these differences can be the difference between a successful and unsuccessful appeal.
Is Your Plan an ERISA Plan?
Most employer-sponsored health plans are ERISA plans. Your plan is subject to ERISA if it is sponsored by a private-sector employer (not a government entity or church). Government employee plans and church plans are generally not ERISA plans and may have different appeal rules.
A key distinction within ERISA plans: self-funded vs. fully-insured. In a self-funded plan, the employer bears the financial risk of claims — the insurance company is just an administrator. In a fully-insured plan, the employer pays premiums to the insurance company which pays claims. Self-funded plans are exempt from state insurance regulations, including state external review laws — they're governed only by federal law.
Your Core Rights Under ERISA §503
ERISA §503 (implemented at 29 CFR §2560.503-1) requires every ERISA plan to establish and maintain a "reasonable claims procedure." Key rights guaranteed by ERISA include:
- Right to a written explanation: Every denial must state the specific reason(s) and the specific plan provisions relied upon
- Right to the claim file: Free access to all documents, records, and information relevant to your claim
- Right to appeal: At least one level of internal appeal, with at least 180 days from denial to file
- Right to an independent reviewer: The appeal reviewer must not be the person who made the original denial or a subordinate
- Right to present evidence: You can submit written comments, documents, and other information as part of your appeal
- Right to a written appeal decision: The appeal decision must include specific reasons and references to plan provisions
The Administrative Record Rule — Critical for ERISA
In ERISA litigation, courts generally review decisions based on the "administrative record" — the documents that were in the file when the plan made its decision. This means that if you lose your internal appeal and eventually sue, courts may not consider evidence you failed to submit during the appeal process. This makes a thorough, well-documented internal appeal critically important. Submit ALL of your evidence during the internal appeal — don't hold anything back.
Discretionary Authority and the Standard of Review
Many ERISA plans include "discretionary authority" clauses — language granting the plan administrator broad authority to interpret the plan and make benefit determinations. When a plan has such a clause, courts review decisions under a deferential "abuse of discretion" standard, meaning the court only overturns the decision if it was arbitrary and capricious. Without this clause, courts apply a de novo standard (no deference to the insurer).
Some states have enacted laws prohibiting discretionary authority clauses. California, Illinois, New York, New Jersey, Oregon, Washington, and others have such laws for fully-insured plans. If your plan is fully-insured in one of these states, the plan cannot have a discretionary authority clause, which is favorable for legal challenges.
ERISA Conflicts of Interest
When a health plan both determines eligibility for benefits and pays those benefits (which is the case for insurance company-administered plans), there is an inherent conflict of interest. Under Metropolitan Life Ins. Co. v. Glenn (U.S. Supreme Court, 2008), courts must consider this conflict when reviewing ERISA denials. The degree of conflict can affect how much deference a court gives to the insurer's decision.
In your appeal, document any indications that the denial was financially motivated rather than clinically supported. Reviewer qualifications and any evidence of systemic over-denial in your plan are relevant to this analysis.
ERISA Section 502(a) — Your Legal Remedies
If you exhaust your ERISA appeals and your claim is still denied, you can bring a civil action under ERISA §502(a). You can sue to:
- Recover benefits due to you under the plan
- Enforce your rights under the plan
- Clarify your future rights under the plan
Important limitation: ERISA preempts state insurance law claims for employer plans (except for fully-insured plans in some contexts). This means you typically cannot sue under state bad faith insurance laws for ERISA plans — your remedy is generally limited to the benefits claimed plus potentially attorney's fees.
Filing with the DOL
The U.S. Department of Labor Employee Benefits Security Administration (EBSA) enforces ERISA and can intervene in certain cases. If you believe your plan violated ERISA's claims procedure rules, you can file a complaint at:
- Online: dol.gov/agencies/ebsa/about-ebsa/ask-a-question
- Phone: 1-866-444-3272
- Also: Request your plan's Summary Plan Description, which is legally required to include the complete appeals process
Getting a Copy of Your Plan Documents
Under ERISA §104(b)(4), plan participants can request copies of the plan's Summary Plan Description (SPD), the actual plan document, and any other instruments under which the plan is established or operated. The plan must provide these documents within 30 days of request. The SPD is essential — it contains the complete explanation of your coverage and appeal rights. Your HR department must provide it free of charge (the actual plan document may have a small per-page copy fee).
