ERISA preemption: why insured and self-funded plans differ.
State health insurance laws do not apply the same way to every employer plan. Whether a plan is insured or self-funded often decides which state mandates reach it.
The three clauses.
Preemption
ERISA supersedes state laws that relate to employee benefit plans. This broad rule is the starting point. For employers, the practical question is which rules govern a given plan, federal or state. Preemption is a legal doctrine with many exceptions, so confirm the details with counsel.
Savings Clause
ERISA does not exempt anyone from state laws that regulate insurance. That means state insurance laws can reach the insurance an employer buys. Employers with insured coverage should expect state insurance requirements to shape what the carrier can offer, such as required benefits and notice rules. Ask the carrier which mandates apply.
Deemer Clause
A self-funded plan cannot be deemed an insurer for purposes of state insurance law, so state insurance laws generally do not apply directly to it. This is why funding type matters so much. Self-funded employers still face federal requirements and some state laws, so they should not assume they are free of state rules without legal advice.
The three clauses behind preemption.
The Preemption Clause
ERISA supersedes state laws that relate to covered employee benefit plans, with listed exceptions. The clause is broad but not unlimited, and courts have read it in different ways over time. Employers should treat it as a starting point and get legal advice before relying on it.
The Savings Clause
State laws that regulate insurance survive, so insurers remain subject to state insurance regulation. In practice, a fully insured employer’s plan is shaped by the insurance laws of the state where the policy is issued. The carrier can usually explain which of those requirements apply to the contract.
The Deemer Clause
A self-insured plan is not treated as an insurer for state law purposes, which generally keeps state insurance laws from regulating it directly. This keeps most state insurance rules from reaching a self-funded plan directly. It does not remove federal requirements, and other state laws may still matter, so employers should confirm with counsel.
Insured Plans
Through the savings clause, state mandates can reach the insurance contract the carrier issues to the employer. Employers buying insured coverage generally see these mandates built into the policy, so required benefits and notices often come through the carrier. Review the contract and ask the carrier about changes.
Self-Funded Plans
State insurance laws generally cannot regulate the plan directly, although other state laws that are not preempted may still apply. Employers with self-funded plans should still plan for federal requirements, plan document duties and any state laws that apply outside insurance regulation. A benefits attorney can help sort out which ones.
Listed Exceptions
Generally applicable state criminal laws and certain qualified domestic relations and medical child support orders are not preempted. These exceptions matter when an employer receives a court order about a family member’s coverage. Employers should route such orders to counsel and the plan’s administrator, and follow written procedures.

What plan sponsors can do.
Know Your Funding Type
Confirm whether each plan is fully insured or self-funded before applying any state mandate. Plan documents and carrier contracts usually show the funding arrangement. Employers with more than one plan should check each one, since the answer can differ from plan to plan.
Remember Stop-Loss Does Not Change It
Courts have held that buying stop-loss coverage does not turn a self-funded plan into an insured one for this purpose. Stop-loss protects the employer against large claims but does not make the plan an insurance policy for state law purposes. Employers should still review the arrangement with counsel.
Do Not Assume
Federal rules still apply to self-funded plans, and some state laws apply regardless. Ask counsel about any specific mandate. Preemption is rarely all or nothing, and the answer can depend on the specific law. Before dropping a state-mandated benefit or notice, get a legal opinion, since the risk sits with the employer.
Three questions to settle.
Is Each Plan Insured Or Self-Funded
Write it down by plan. Include medical, dental, vision and any other plan, since funding can differ. A simple chart helps HR and counsel see which state rules may apply to each one. Review it with counsel at each renewal.
Which State Mandates Do We Follow
Ask the carrier which apply to insured coverage. Carriers usually track mandates for the states where policies are issued. Ask for a written list and review it whenever coverage is renewed or the employee footprint changes. Counsel can confirm the list is complete.
Do Plan Documents Say So
Check that the documents reflect the funding type. Documents that describe the wrong funding type can create confusion in claims and compliance. Compare the plan document, the summary description and the carrier or administrator contract at each renewal. Correct any mismatch with counsel.
Common Questions About ERISA Preemption
Do state benefit mandates apply to my plan?
If the plan is insured, state insurance laws generally reach the policy. If it is self-funded, they generally do not apply directly.
Does the same hold for Michigan mandates?
The same ERISA framework applies, so check which Michigan mandates apply to your funding type.
Is a self-funded plan free of all state law?
No. ERISA preemption is not unlimited, and other laws can still apply.
Does stop-loss make a plan insured?
Not for this purpose, according to court decisions.
Where does the law say this?
In ERISA section 514, codified at 29 U.S.C. 1144.
