PEO Health Insurance: Plan Structures and Tradeoffs

"PEO health insurance" is not one product. Behind the phrase sits one of several structures: a PEO-sponsored arrangement covering employees of many client companies, a client-specific policy the PEO administers, or a mix by state and headcount. The structure determines who sponsors the plan, which regulator watches it, what happens at renewal, and what you keep when you leave, so identifying it is the first job in any benefits comparison.

A PEO does not transform a 15-person company into a large employer for all insurance purposes. It can offer access to a plan lineup, underwriting outcome, and administration that differ from the direct small-group market. The census, employee states, carrier, and plan terms determine whether that option is better for the employer.

The structures in plain language

PEO-sponsored arrangement. The PEO sponsors a program in which eligible worksite employees of many clients participate. The Department of Labor generally treats an arrangement providing health benefits to the employees of two or more unrelated employers as a multiple employer welfare arrangement (MEWA) under ERISA. MEWAs answer to both federal ERISA rules and state insurance regulation, which varies by state and by whether the arrangement is fully insured or self-funded.

Client-specific policies. In some states or for some clients, the PEO arranges a policy specific to your company, in your or the PEO's name, and administers it. Pricing then reflects your group, not a pooled program.

Hybrids. Large PEOs commonly run different structures in different states. One proposal may combine them, so identify the plan, sponsor, funding arrangement, and governing state for every employee group.

Fully insured vs self-funded

A fully insured arrangement pays a licensed carrier a premium, and the carrier bears claims risk. A self-funded arrangement pays claims from plan assets, with stop-loss insurance capping the damage. Self-funded MEWAs have a difficult regulatory history, and several states restrict them; fully insured arrangements put a carrier's solvency and filed rates between you and claims volatility.

Ask whether the medical plan is fully insured and which carrier issues it. If any layer is self-funded, ask who bears the risk, what stop-loss applies, what happens to incurred-but-unpaid claims if the arrangement terminates, and which state insurance department has jurisdiction. The answers should come from plan and insurance documents.

What determines whether the offer is competitive

Compare the actual plans on your actual census, against a broker quote with the same effective date. The variables that decide it:

• Carrier and network. A national-name carrier with a narrow network in your county is not the same product as the same name with a broad one. Check networks where employees live.
• Plan design. Deductibles, out-of-pocket maximums, copay structure, and formulary, plan by plan, not tier labels.
• Rates and tiers. Total premium by coverage tier, and how age banding or composite rating applies to your group.
• Contribution strategy. The employer share the proposal assumes, in dollars. A "cheaper" plan with a higher assumed employer contribution is not cheaper for you.
• Participation and eligibility rules. Minimum participation percentages, waiting periods, and hour thresholds that could disqualify part of your workforce or your whole group later.
• Renewal mechanics. Who sets the renewal, when you learn the number, and what notice the contract guarantees. Ask for the PEO's recent renewal ranges for groups like yours, in writing; treat a refusal as data.

The exit and mid-year questions

PEO coverage generally ends with the service agreement, so the exit is part of the purchase. Three questions to settle before signing rather than after notice:

1. Continuation. Which continuation rights apply to employees when your company leaves the arrangement, and who administers them during the transition?
2. Deductible and accumulator transfer. If you leave mid-plan-year, do employees restart deductibles on the replacement plan? Carriers sometimes credit accumulators at the buyer's request; nobody does it automatically.
3. Data. Will the PEO deliver the census, enrollment, and claims-experience data a replacement underwriter needs, and on what timeline? Larger groups cannot get competitive replacement quotes without experience data, and the contract is the only leverage that reliably produces it.

Documents to request with every proposal

Ask for the summary plan description or certificate of coverage, the summary of benefits and coverage for each plan, the funding description, carrier and network names, eligibility and participation rules, the assumed employer contribution, the renewal date, and continuation terms at exit. Give the same census and effective date to a broker so the direct-market quote uses comparable inputs.

When PEO coverage fits

Choose the PEO benefits route when the actual plans, on your census, at your contribution level, in your counties, beat the direct market by enough to carry the bundle's other terms, and when you have priced the exit. Choose the direct route when plan ownership, carrier continuity, or a strong existing broker relationship is worth more than the bundle. Either answer is defensible; reaching it without reading the plan documents is not.
