Plan Structure
Who Actually Denied Your Claim?
The logo on your insurance card doesn't tell the whole story. A carrier can insure the benefits, administer the claims, run the network, operate the member portal, or handle several of those at once. In an employer plan specifically, the employer's own plan might fund the benefits while a national carrier just processes the claims. Knowing which arrangement you're in helps you find the right procedure and, if needed, the right escalation path.
Who's Actually Involved
The parties that can control your appeal
-
In a fully insured plan
The employer or individual pays a premium and the insurance company carries the actual claim risk. State insurance regulation generally plays a central role here, alongside applicable federal protections. The carrier is more likely to be both the insurer and the claims decision-maker.
-
In a self-funded employer plan
The employer's own plan generally carries the financial risk for benefits, while a carrier or third-party administrator processes the claims. The carrier's network and branding might still be all over the ID card even though the plan document names a different formal administrator and appeal procedure. Federal ERISA rules commonly apply to private-employer plans here, with some exceptions. None of this means an HR employee personally reviewed the claim. It just means the legal responsibilities can look different from a fully insured product using the same carrier brand.
-
Other entities can be involved too
A plan sponsor, usually the employer establishing the benefit. A plan administrator or fiduciary, the person or entity the plan names as responsible for specific administrative duties, with the exact scope spelled out in the plan documents. A claims administrator or TPA, who processes claims, issues EOBs, applies plan rules, and may run appeals under delegated authority. A pharmacy benefit manager running a separate prior-authorization and appeal process. A utilization-management vendor reviewing medical necessity or site of care. And the provider or billing office itself, which submits the claim and controls correction, coding, and authorization records on its side.

To figure out your own structure
Check the denial notice, the EOB, the back of the ID card, the Summary Plan Description, the plan document, the SBC, the employer benefits portal, annual enrollment materials, and the carrier's member portal. A useful question for the employer benefits team: "Is this medical plan fully insured or self-funded, and where can I get the current Summary Plan Description and claim-appeal procedure?"
Why It Matters
What the plan-type distinction actually changes
This distinction can change which rules govern the internal appeal, which external-review process applies, whether the state insurance department regulates the decision at all, whether the Department of Labor can help, whether a plan fiduciary has a role, which documents you can actually request, and where the appeal has to go. That said, the denial notice is still the immediate filing authority. Don't hold off on the appeal while you research plan structure in the background.
The Safer Sequence
Preserve the deadline while you sort out the structure
Preserve the deadline, file through whatever procedure the denial notice actually gives, confirm the plan's funding and administration, request the governing documents, and use the correct escalation path if the denial holds. The carrier name matters. The plan type usually matters more.

Frequently Asked Questions
Is the company on my insurance card always the insurer?
No. It could be the insurer, the network, the claims administrator, or some combination.
How do I know whether my plan is self-funded?
Ask the employer's benefits team and check the Summary Plan Description.
Can my employer reverse a denial?
Authority varies by plan. Some employers keep fiduciary or review authority, others delegate it entirely. Check the plan document.
Does state insurance law apply to a self-funded plan?
State insurance mandates generally don't regulate self-funded employer benefits the way they regulate insurance policies, but verify the specific issue and available help for your situation.
