If you receive health insurance through your employer and your claim has been denied, one of the most important things you need to know is whether your plan is self-funded. If it is, you're in a legal universe governed entirely by a federal law called ERISA — and that changes nearly everything about your rights, your appeal options, and your potential legal remedies.

What Is a Self-Funded ERISA Plan?

In a self-funded (or self-insured) employer health plan, the employer bears the financial risk of paying employees' health claims directly. The employer isn't buying insurance from a carrier in the traditional sense — it's setting aside funds to pay claims and hiring a third-party administrator (TPA), often a large insurer like Cigna, Aetna, or UnitedHealthcare, to administer the claims.

Approximately 65% of covered workers in the United States are in self-funded plans. If you work for a large employer, there's a good chance your health coverage is self-funded.

How to tell if you're in a self-funded plan:

• Your insurance card may show an insurance company name, but look for language like "Administrative Services Only" or "ASO"
• Your Summary Plan Description (SPD) may state "This plan is self-insured"
• Ask your HR department directly

Why ERISA Preempts State Law — and What That Means

The Employee Retirement Income Security Act of 1974 (ERISA) contains a broad preemption clause that displaces state laws relating to employee benefit plans. For self-funded employer plans, this means:

State insurance mandates don't apply: If your state requires insurers to cover certain treatments (IVF, autism therapy, mental health benefits above federal minimums), those mandates don't apply to your self-funded plan. The plan's own documents are the governing source of coverage — and the plan can exclude treatments that state law would require an insured plan to cover.

State External Independent Review: Complete Guide" class="auto-link">external review may not apply: Many states require health insurers to offer external independent review of denied claims. But self-funded plans are not "insurance companies" under state law, so state external review requirements may not apply. Whether federal external review requirements under the ACA apply to self-funded plans has been complex — regulations have extended some ACA requirements to self-funded plans, but implementation is uneven.

State bad-faith remedies may not be available: In most states, insurers can be sued for bad faith in handling claims, with remedies including punitive damages and attorney's fees. Under ERISA preemption, these state tort remedies are generally unavailable for self-funded plan participants. Your remedy is typically limited to the value of the denied benefit, plus attorney's fees in some cases under ERISA's fee-shifting provision.

State insurance department complaints may be limited: Because self-funded plans aren't insurance companies, your state's insurance commissioner may have limited authority over them. Federal oversight of self-funded ERISA plans rests primarily with the Department of Labor.

What Rights You Do Have Under ERISA

Despite the limitations of ERISA preemption, self-funded plan participants have meaningful rights:

The right to a full and fair review: ERISA requires that plan participants receive a written denial with specific reasons, a description of additional information needed, and a description of the appeal process. The plan must provide a meaningful internal appeal, reviewed by someone different from the original decision-maker.

The right to plan documents: You can request a copy of the plan document, Summary Plan Description, and the specific claims criteria used in the denial. The plan administrator must respond within 30 days.

The right to appeal: ERISA requires at least one level of internal appeal. If internal appeal is denied, ERISA creates a right to bring a federal lawsuit to recover denied benefits.

Federal mental health parity: The Mental Health Parity and Addiction Equity Act (MHPAEA) applies to self-funded plans. If your plan applies more restrictive criteria to mental health or substance use disorder claims than to comparable medical/surgical claims, that's a federal law violation — regardless of ERISA preemption.

The ACA's extended requirements: The ACA extended several consumer protections to self-funded plans, including:

• Coverage of preventive services
• Coverage of children on parents' plans to age 26
• Prohibition on lifetime and annual dollar limits for essential health benefits
• Some external review requirements

The Standard of Review Problem

One of the most consequential aspects of ERISA plan denials is the judicial standard of review. If a self-funded plan's documents give the plan administrator discretion to interpret plan terms and determine eligibility, courts review the plan's decision under an "abuse of discretion" standard — meaning the court won't second-guess the plan's interpretation unless it was unreasonable.

This is a significant departure from how health insurance disputes are handled in the individual market, where courts apply a de novo standard (reviewing the decision fresh, without deference to the insurer).

The practical implication: winning an ERISA lawsuit requires not just showing the plan was wrong, but often showing the plan's interpretation was unreasonable — a higher bar.

Appeal Strategy for Self-Funded Plans

Given ERISA's constraints, the appeal process itself is critical. Because judicial review is typically limited to the administrative record (the documents submitted during the internal appeal), building a strong internal appeal record is essential.

Your internal ERISA appeal should include:

• Every piece of medical evidence supporting coverage
• Your treating physician's letter and clinical records
• Published clinical guidelines and peer-reviewed research
• A clear legal argument for why coverage is required under the plan documents
• Any applicable federal law arguments (MHPAEA, ACA requirements)

Don't save arguments for court — the court may not consider evidence that wasn't part of the administrative record.
