ERISA Preemption and Self-Funded Plans, Made Simple
“ERISA preempts that” can sound like the end of a health plan conversation.
It should be the beginning of a better question.
For a CEO or CFO, the useful question is not whether ERISA preemption exists. It does. The useful question is: which rule applies to this plan, this vendor, this contract, and this decision?
The Source Idea in Plain English
On July 22, 2026, a National Association of Insurance Commissioners working group met to review a new draft guidance document about ERISA preemption and state pharmacy benefit manager laws. The draft explains why the answer is not as simple as “federal law wins” or “state law applies.”
ERISA generally creates a federal framework for private employer benefit plans. State insurance laws can still regulate insurance policies and insurance companies. A self-funded employer plan, however, is not supposed to be treated as an insurance company simply so a state can regulate the plan as insurance.
The draft also discusses recent PBM cases that reached different results. Some state rules affected PBM costs or incentives without forcing a health plan to use a particular benefit design. Other rules reached more directly into pharmacy networks or plan administration. The details of the rule mattered.
That is the business lesson: preemption is a map of responsibility, not a magic word that removes every state rule.
Why This Matters to Self-Funding
A fully insured employer buys a state-regulated insurance policy. A self-funded employer pays claims from plan assets and hires outside companies to administer the plan, manage the pharmacy benefit, provide a network, and protect the plan with stop-loss coverage.
That structure gives the employer more control. It also creates more places where different rules can meet.
The employer's health plan may be governed primarily by federal law. The stop-loss policy is still an insurance contract. A PBM may be subject to state pharmacy or business rules. A TPA may hold state licenses. Providers operate under state law. Employee privacy, leave, tax, and reporting questions can bring other federal and state requirements into the same room.
Self-funding does not make the company law-free. It changes the legal and operating framework around the plan.
Three Mistakes Leaders Should Avoid
First, do not assume the vendor owns the legal answer. A TPA or PBM can explain how it administers a requirement. That is not the same as a plan-specific legal analysis. The vendor's contract may also allocate responsibility back to the employer.
Second, do not confuse preemption with permission. A state mandate may not control a self-funded plan, but the employer still needs a documented plan decision. Leadership should know whether a benefit was included by choice, required by another rule, or left out after a deliberate review.
Third, do not use one answer for every state. Midwest employers often have employees in several states. PBM, pharmacy, provider, stop-loss, leave, and other rules can affect different parties in different ways. A multistate workforce makes a written responsibility map more important, not less.
Build a One-Page Rule Map Before Renewal
Leadership does not need a fifty-page legal memo for every operational decision. Start with a one-page map that names the issue, the governing document, the responsible party, and the professional who confirmed the answer.
For each major plan area, ask:
- Is the plan fully insured, level-funded, self-funded, or participating in a captive?
- Which entity is being regulated: the employer plan, the insurer, the TPA, the PBM, the pharmacy, or the provider?
- Which federal rule, state rule, plan document, or contract controls the decision?
- Does the vendor agreement clearly assign responsibility and access to data?
- Has qualified benefits counsel reviewed any uncertain or contested point?
This map should be tied to the current plan documents and contracts. If it is based on an old carrier presentation or a sentence from a vendor email, it is not ready for the renewal file.
What This Means for PBM Review
The NAIC draft is especially useful because PBM rules sit at the intersection of plan design, pharmacy operations, cost, and state regulation.
An employer should not stop at “our plan is self-funded.” Ask the PBM to identify which state requirements it applies, which it does not apply, and why. Then compare that explanation with the contract, the plan document, the pharmacy network terms, and counsel's advice.
That review can expose practical questions:
- Can the employer see spread, rebate, and pharmacy reimbursement information?
- Who controls the formulary and pharmacy network?
- Does a state rule affect the PBM's conduct even if it does not directly regulate the plan?
- Is the vendor using “ERISA” to explain a real legal boundary or to avoid a business question?
A legal label should never replace a financial explanation.
Where Superior Insurance Advisors Fits
Superior Insurance Advisors helps CEOs, CFOs, and business owners connect the legal structure of a self-funded plan to the contracts, claims data, pharmacy economics, and renewal decisions underneath it.
That does not replace benefits counsel. It gives counsel and leadership a cleaner set of facts to review. It also helps the company separate questions for the advisor, the TPA, the PBM, the stop-loss carrier, and the attorney.
Paul.Health is a practical starting point for organizing that conversation before renewal pressure turns an unanswered question into an expensive assumption.
A Practical Decision Checklist
- Confirm the plan's funding structure and ERISA status.
- List every state where employees receive benefits.
- Identify the regulated entity for each disputed rule.
- Match vendor answers to signed contracts and current plan documents.
- Send unresolved preemption questions to qualified benefits counsel.
- Keep the final analysis and decision in the renewal file.
The decision question for leadership is: when someone says “ERISA preempts that,” can your team show exactly what “that” is, who the rule applies to, and which document supports the answer?
