Every self-funded health plan excludes occupational injury. The wording varies little. One Cigna-administered plan document puts it this way:
Care and treatment of an Injury or Sickness that is occupational, that is, arises from work for wage or profit including self-employment and military service.
Another plan is blunter, excluding expenses for injury or illness arising out of employment “whether or not such policy is actually in force”. The exclusion attaches to the nature of the injury, not to whether workers’ compensation actually pays.
Which raises the question of what happens when workers’ compensation does not pay, and the worker needs treatment anyway.
The sequence
A warehouse employee reports back pain. The employer disputes that it happened at work, or the carrier disputes it, and the comp claim gets denied. The employee still has a back injury and a health plan card. He treats under group health.
Eighteen months later, a workers’ compensation judge finds the claim compensable.
The plan has now paid, in some cases well into six figures, for treatment it never owed. If the plan is self-funded and carries stop-loss above a specific deductible, the stop-loss carrier reimbursed part of it, and the stop-loss carrier has an interest in the outcome it may not know about.
Where the recovery comes from
Self-funded ERISA plans pursue recovery through an equitable lien under ERISA section 502(a)(3), attaching to the portion of the workers’ compensation settlement equal to the benefits the plan paid.
Plan documents anticipate this. The same Cigna SPD that excludes occupational injury also carries an erroneous payments clause allowing the plan to deduct benefits paid “pursuant to a claim for which benefits are recoverable under any policy or act of law providing for coverage for occupational injury or disease to the extent that such benefits are recovered”.
The plan pays under protest, then claws back after the compensability ruling. That is the design.
The states do not agree on procedure
Whether the plan can intervene directly in the pending workers’ compensation claim depends on where the injury happened.
California, Minnesota, Pennsylvania, New Jersey, Indiana, Michigan, and Texas permit a health plan to intervene in the comp proceeding.
North Carolina, Illinois, and Wisconsin prohibit it. The plan must pursue the employee or the employer separately.
Delaware provides no statutory authority either way.
A recovery unit working a national book is therefore running three different playbooks depending on the state, and the difference determines whether you assert the lien inside the comp case or file separately after it resolves.
The part that consumes the hours
Here is where the recovery gets difficult in a way that is not obvious from the legal framework.
Recovery is capped at the workers’ compensation fee schedule, not at what the group health plan actually allowed.
Group health paid a negotiated commercial rate. The comp fee schedule in that state sets a different, and usually lower, allowable for the same service. The plan cannot recover the difference. So every line item has to be re-priced.
That means taking the HCFA-1500s and UB-04s the plan already adjudicated, matching each service line to the applicable workers’ compensation fee schedule for the state and the date of service, and computing the recoverable amount line by line. Subrogation firms that do this work regularly retain third-party bill review specialists for exactly this step, because the alternative is a lawyer at an hourly rate reading CPT codes.
On a claim with two surgeries, a course of physical therapy, and eighteen months of pharmacy, that is several hundred line items across multiple fee schedule versions.
There is a second, quieter task alongside it. Somebody has to separate the treatment that relates to the compensable injury from treatment that does not. A claimant with a compensable lumbar injury and pre-existing diabetes generated claims for both. Only one set is recoverable, and the split is a clinical judgment made from the records rather than from the billing data.
The reverse direction
The traffic runs both ways, and comp payers are exposed to the mirror image.
A workers’ compensation payer that accepts a claim and later establishes the condition was not occupational has paid benefits it did not owe. Recovery there runs through state-specific overpayment procedures rather than ERISA, and the evidentiary question is the same one: what do the records show about mechanism, onset, and prior condition.
There is a limit on what comp payers can push downstream. In Thomas v. Logue, 191 N.E.3d 1155, the Ohio Court of Appeals held that the Bureau of Workers’ Compensation could not recover its medical record review and medical report preparation costs through subrogation. The court treated those as administrative costs incident to the discharge of the Bureau’s duties. The payer buys the review, and the payer keeps the cost.
What a defensible file looks like
Recovery cases turn on the record, and the record has to be organized before anybody can argue about it.
The chronology has to establish mechanism and onset, because that is what the compensability finding rested on and what an employer disputing the lien will attack. It has to identify every provider and every date of service, because a gap means an unrecovered dollar. It has to separate compensable from non-compensable treatment with a stated basis for each call. And it has to carry a line-item re-pricing against the correct fee schedule version for each date of service.
None of that is legal work. All of it has to exist before the legal work starts.
Why this sits between two departments and gets missed
The structural reason these recoveries get left on the table is organizational.
The group health side sees a claim that was paid and closed. The workers’ compensation side sees a claim that was denied and then lost. The stop-loss carrier sees a reimbursement it already made. No single person is looking at both files, and in most organizations no single system holds both.
The compensability ruling that triggers the recovery arrives at the comp desk, which has no reason to tell the health plan.
Plans that recover consistently have one thing in common. Somebody runs a periodic reconciliation between comp denials and group health payments on the same member, and flags matches for review when the comp claim resolves.
That reconciliation is a data exercise. What follows it is a records exercise. Neither requires a lawyer until the demand goes out.
