ERISA
ERISA Appeal Rights: What Every Employer Plan Member Needs to Know
If your health insurance comes through a private employer, ERISA gives you the right to a full and fair review of any denied claim. The governing regulation — 29 CFR § 2560.503-1 — specifies what your insurer must do, when they must do it, and what happens if they fail. Most people covered by employer health plans have never heard of it. Their insurers have.
What is ERISA?
The Employee Retirement Income Security Act of 1974 (ERISA) is a federal law that sets minimum standards for private employer-sponsored benefit plans, including health insurance. If your employer is a private company and provides health benefits, ERISA almost certainly governs your plan.
Who is NOT covered by ERISA:
- –Government employees (federal, state, local)
- –Church plan members
- –Self-employed individuals
- –Those on individual marketplace (ACA) plans — governed by PHS Act § 2719 instead
For marketplace and individual plans, see the ACA external review rights and the federal appeal deadline rules.
The core legal framework
Two documents govern ERISA health plan appeals:
ERISA § 503 (29 U.S.C. § 1133) — the statutory basis. Requires every plan to:
- –Provide adequate written notice of any denied claim, with reasons
- –Provide a reasonable opportunity for a full and fair review by the plan
29 CFR § 2560.503-1 — the Department of Labor's implementing regulation. Specifies what "adequate notice" and "full and fair review" actually mean in practice. This is the regulation your appeal letter cites.
What "full and fair review" means
Under 29 CFR § 2560.503-1(h), you have the right to:
- –Review your claims file — all documents, records, and information relevant to the claim. This includes any guidelines, clinical criteria, or medical literature the insurer relied on.
- –Present evidence and testimony — you can submit additional documents, testimony, or medical opinions in support of your appeal.
- –Have your appeal reviewed by someone new — the reviewer cannot be the same person who made the original denial, and cannot be a subordinate of that person.
- –Receive a written decision — the insurer must address every argument and piece of evidence you submitted. A form letter that ignores your arguments is a regulatory violation.
Required timelines
Under 29 CFR § 2560.503-1(i), insurers must decide appeals within:
| Claim type | Decision deadline |
|---|---|
| Non-urgent post-service claims | 60 days |
| Pre-service claims | 30 days |
| Urgent care claims | 72 hours |
| Concurrent care decisions | 24 hours |
If you do not receive a decision within these timeframes, the plan has violated the regulation. Document it.
What the denial notice must include
Under 29 CFR § 2560.503-1(g), every denial must provide:
- –The specific reason(s) for the denial
- –Reference to the specific plan provision(s) on which the denial is based
- –A description of additional material or information needed (if applicable) and why
- –A description of your review procedure and applicable time limits
- –For clinical denials: the specific clinical criteria applied and how to obtain the internal rules used
If your denial letter is vague — "not medically necessary" with no further explanation — it likely violates this provision. An appeal letter can specifically cite the inadequacy of the notice as an additional ground.
The appeal letter and regulatory citations
A generic appeal letter asks the insurer to reconsider. An effective appeal letter cites the specific provisions of 29 CFR § 2560.503-1 that govern the insurer's obligations and demands a specific, documented response.
Key citations your appeal letter can invoke:
- –§ 2560.503-1(g) — the denial failed to include required specific reasons and plan provision references
- –§ 2560.503-1(h) — you are entitled to full and fair review including all clinical criteria applied
- –§ 2560.503-1(i) — the required decision timeline and consequences of non-compliance
- –§ 2560.503-1(l) — deemed exhaustion if the plan fails to follow its own procedures
Rebuttal generates appeal letters that cite these provisions in the context of your specific denial code and plan type. Draft your appeal letter.
Deemed exhaustion: your escalation option
Under 29 CFR § 2560.503-1(l), if the plan fails to strictly adhere to the requirements of this regulation — missing deadlines, failing to provide required notices, denying a full and fair review — your claim is deemed exhausted.
Deemed exhaustion means you are not required to complete the internal appeal process. You can immediately:
- –Pursue external review (where available)
- –Seek judicial review in federal court
This is a significant provision. If your insurer is slow, unresponsive, or procedurally non-compliant, document every interaction with dates, names, and reference numbers.
External review under ERISA
External review rights for ERISA plans are more limited than for ACA plans. The availability depends on:
- –Whether your state has an external review mandate
- –Whether your plan is fully insured (subject to state insurance law) or self-funded (generally exempt from state mandates)
- –Whether the Department of Labor's voluntary external review process applies
For self-funded employer plans that are not subject to state mandates, the ACA created a federal external review process administered by the Department of Labor. File at dol.gov/agencies/ebsa.
Frequently asked questions
What is ERISA and does it cover my health plan?
ERISA governs most private employer-sponsored health plans. If your insurance comes through your job at a private company, ERISA almost certainly applies. Government employees, church plan members, and marketplace plan enrollees are generally not covered by ERISA.
What does "full and fair review" mean under ERISA?
Under 29 CFR § 2560.503-1(h), full and fair review means you can examine your entire claims file, submit additional evidence, and receive a written decision that addresses every argument you raised. The reviewer must be independent of the original decision-maker.
What is deemed exhaustion?
Under 29 CFR § 2560.503-1(l), if your insurer fails to follow the regulation's requirements — missing deadlines, ignoring your arguments, violating notice requirements — your claim is deemed exhausted. You can proceed directly to external review or federal court without completing the internal process.
