What Is a Fully Insured Plan?

What a Fully Insured Plan Means

A fully insured plan is an employer-sponsored health benefit arrangement where the employer pays fixed premium payments to an insurance company, and the insurer assumes full financial responsibility for paying employee medical claims. The insurance carrier sets premium rates based on expected claims costs, administers the plan, maintains provider networks, and processes all claims. If actual claims exceed premium revenue, the insurer absorbs the loss. Fully insured plans are regulated as insurance products by state departments of insurance, which means they must comply with state mandated benefits, solvency requirements, and consumer protection laws that do not apply to self-funded ERISA plans.

Why a Fully Insured Plan Matters

Knowing your plan is fully insured unlocks state-level appeal protections that self-funded plan members cannot access. Fully insured plan denials can be escalated to independent external review through your state insurance department after internal appeals are exhausted. State prompt-pay laws may impose penalties on insurers that delay payment beyond statutory timeframes. State mandated benefit laws may require coverage for services that a self-funded plan could exclude. For providers and patients facing denials, fully insured status means the insurer on the ID card is both the claims administrator and the entity financially responsible for payment — simplifying accountability compared to self-funded arrangements where the employer holds risk.

How a Fully Insured Plan Affects Your Claim

Claims submitted to fully insured plans are adjudicated against the insurer's medical policies, provider contracts, and the state's mandated benefit requirements. The insurance company bears direct financial responsibility for every paid or denied claim, giving it incentive to apply utilization management aggressively. Denial notices from fully insured plans must comply with ACA appeal rights requirements, including clear explanation of denial reasons and information about external review options. State-specific timely filing limits, appeal deadlines, and external review eligibility criteria apply. A fully insured denial overturned through external review is binding on the insurer — a powerful recovery tool not available for ERISA-governed self-funded plans.

What to Do About a Fully Insured Plan Denial

File a first-level internal appeal with the insurance company within the deadline stated on your denial notice, typically 180 days. Include clinical documentation, the insurer's medical policy, and any state mandated benefit laws supporting coverage. If the internal appeal is denied, request external review through your state insurance department or its designated Independent Review Organization. External review decisions are binding on the insurer for fully insured plans. You can also file a complaint with your state insurance commissioner if the insurer violates prompt-pay or claims processing standards.

Frequently Asked Questions

How is a fully insured plan different from self-funded?

In a fully insured plan, the insurance company assumes financial risk and pays claims from premium revenue. In a self-funded plan, the employer pays claims directly. Fully insured plans are regulated by state insurance departments; self-funded plans fall under ERISA.

Can I request external review for a fully insured plan denial?

Yes. Fully insured plans are subject to state external review requirements under the ACA. After exhausting internal appeals, you can request an independent review by a state-certified organization, whose decision is binding on the insurer.

Are fully insured plans more common for small employers?

Yes. Small employers with fewer than 100 employees overwhelmingly use fully insured plans because they lack the scale to self-fund effectively. Larger employers more commonly choose self-funded arrangements.

What state protections apply to fully insured plans?

Fully insured plans must comply with state mandated benefits, prompt-pay laws, network adequacy standards, and consumer complaint processes through the state insurance department. These protections do not apply to self-funded ERISA plans.
