Your deadline
The internal appeal deadline governs everything else. File that first, then open the other channels while it is pending. Nothing here is a reason to let the appeal clock run.
What to do
Work out what kind of plan you have first
Everything below branches on this. A fully insured plan, a self-funded employer plan, a government employer's self-funded plan, Medicaid and Medicare each have different regulators and different routes.
File the internal appeal
This is the one with a deadline and the one that unlocks external review. Do it first and do it on time.
Complain to your state insurance department
For fully insured plans they regulate your insurer directly. For self-funded plans their authority is limited, but the complaint still creates a dated public record and often produces a written response from the plan that you would not otherwise get.
Find the federal regulator for your plan type
Name them, because the rest of this site does and this is the page whose job is routing. A private employer plan answers to the DEPARTMENT OF LABOR. A state or local government employer plan answers to CMS, through its Center for Consumer Information and Insurance Oversight. Federal employee coverage answers to OPM. A complaint at this level addresses PROCESS — missed deadlines, missing appeal rights, a missing external review process — rather than the medical merits. If you are unsure which applies, your benefits office knows, and the plan-type pages here set it out.
Go to whoever actually pays the claims
On a self-funded plan the insurance company is an administrator and your employer's plan is the payer. The plan sponsor can instruct the administrator. This is a direct route that people rarely use because the logo on the card looks like the decision maker.
Keep one file, and copy the channels to each other
Send the regulator what you sent the plan. Tell the plan you have filed with the regulator. Nothing here is a secret and the fact that a record exists in more than one place is part of what makes it work.
Why parallel rather than sequential
Doing these one after another can take longer than the care can wait. They also do different jobs: the appeal decides your claim, the regulator looks at whether the process was lawful, and the plan sponsor can simply decide differently. Running one at a time means the answer to a question you did not ask arrives first.
There is a second effect. Everything you file becomes part of a record that the next reader inherits. A regulator complaint written from the same file as the appeal is nearly free to produce, and an appeal that has already survived a regulator's questions is a stronger document.
Check whether an external review process actually exists
External review is supposed to be available, but for some plans no compliant process has been set up. Certain self-funded government employer plans in particular can sit in a gap where neither the state process nor the federal one has been arranged.
Find out early rather than at the end. If your denial letter does not tell you how to request external review, ask in writing who administers it. If the answer is that there is none, that absence is itself a compliance problem to raise with the federal regulator, and it may open a route that does not require you to wait.
Deadlines the plan misses are worth writing down
Plans are held to their own timelines. When one passes without a decision, note the date rather than only the frustration. A pattern of missed deadlines is what supports treating the internal process as finished so you can move on, and it is the difference between waiting and having a reason to stop waiting.
Common questions
- Will filing a complaint make the plan retaliate against my appeal?
- Regulators receive these constantly and plans expect them. The realistic risk is not retaliation, it is that a complaint to a body with no authority over your plan type produces a letter telling you so. That is why working out the plan type comes first.
- My plan is self-funded. Does the state insurance department help at all?
- Their direct authority is limited, but a complaint still creates a dated record, and they often tell you which channel does apply. Many people learn from that reply that the employer plan sponsor is the real decision maker.
- Who is the plan sponsor?
- On an employer plan, the employer or the trust that maintains the plan. Your benefits office can tell you, and the plan document names them. On a self-funded plan the sponsor's money pays your claim, which is why they can direct the outcome.
- Do I have to exhaust the internal appeal before anything else?
- Before external review, generally yes, unless deemed exhaustion applies. Complaints to regulators and to the plan sponsor do not have to wait.

- Which federal agency oversees your plan. It depends on the plan type and this page describes the general pattern rather than naming the agency for your situation. Your denial letter, your benefits office, or your state insurance department can tell you.
These are specific and checkable and we have not yet checked them against a primary source. Treat them as a starting point rather than as settled, and do not put them in an appeal without confirming them.
