Who regulates your payer, and why it decides everything
Two patients hand you cards with the same insurer logo. One is covered by a plan subject to your state's prior authorization timelines and appeal rights. The other is not subject to any of them. Nothing on the card tells you which is which, and the difference changes what you can demand and how fast.
#The four regimes
| Plan type | Primary regulator | What that means for prior authorization |
|---|---|---|
| Fully insured commercial | State insurance department | Subject to state prior authorization law: decision timelines, gold carding programmes, appeal rights, and whatever else that state has enacted. |
| Self-funded employer (ERISA) | US Department of Labor, under ERISA | Generally preempts state insurance law. State prior authorization timelines usually do not apply. ERISA claims and appeals rules do. |
| Medicare Advantage | CMS | CMS utilization management rules, including coverage criteria constraints and CMS-0057-F timelines. |
| Medicaid managed care | CMS and the state Medicaid agency | State contract terms plus federal Medicaid rules. Often the tightest timelines and the most documentation. |
The ERISA trap
A self-funded employer plan is frequently administered by a familiar commercial insurer, who processes the claims and answers the phone. The card looks identical to a fully insured card from the same company. But the employer bears the risk, ERISA governs, and the state law you were about to cite does not apply. If a timeline argument matters, establish the funding arrangement before making it.
#How to tell
There is no single reliable indicator, which is itself worth knowing. Practical signals:
- The eligibility response (271) may carry plan-type information, though how much varies by payer.
- Self-funded plans often show an employer name prominently and lack a state-mandated notice block on the card.
- The summary plan description, which the member can request, states the funding arrangement plainly.
- Calling the payer and asking whether the plan is fully insured or self-funded is the direct route and usually works.
#Why it changes your workflow
Timelines you can hold the plan to- State laws frequently impose decision deadlines on fully insured plans. Those deadlines are enforceable and worth citing. On an ERISA plan, the same citation is simply wrong, and citing it costs credibility with the reviewer.
Appeal structure- ERISA plans have a defined internal appeal process and, for most group health plans, an external review pathway. State-regulated plans have state-defined external review. The deadlines and the forms differ.
Gold carding eligibility- Gold carding programmes created by state statute apply to the plans that statute reaches. A practice that has earned an exemption in one plan may still face full review in another from the same insurer.
Which rules are changing- CMS-0057-F reaches Medicare Advantage, Medicaid and CHIP managed care, Medicaid and CHIP fee-for-service, and qualified health plan issuers on the federally facilitated exchanges. It does not reach commercial plans generally, and it does not reach self-funded employer plans. See CMS-0057-F.
What to record
Capture the funding arrangement and the regulator once, on the patient's coverage record, rather than rediscovering it during an appeal. It changes rarely and it determines which lever exists.
