Appealing a "not medically necessary" denial for gender-affirming surgery
A not-medically-necessary denial means the insurer applied its own clinical criteria and decided your documentation did not meet them. It is not a statement that the care is unnecessary. Get the exact criteria in writing, then have your clinicians answer them point by point in the plan's own language.
Deadline. At least 180 days from the day you RECEIVED the denial to file the internal appeal — not from the date printed on the letter. That is the federal floor under 29 CFR 2560.503-1(h)(3)(i); your plan may allow longer, never less.
Applies to All plan types, though the appeal clock is not the same for all of them — check the deadline block below. The appeal route differs by plan type; start at Start here.
Appealing a "cosmetic" denial for facial surgery and related procedures
Cosmetic denials hit facial surgery, chest procedures, and hair removal hardest. The insurer is claiming the procedure changes appearance without treating a condition. The counter-argument is that the procedure treats gender dysphoria, is recognized in the standards of care, and is not being judged the way comparable reconstructive care is.
Deadline. At least 180 days from the day you RECEIVED the denial to file the internal appeal — not the date printed on it. Federal floor, 29 CFR 2560.503-1(h)(3)(i). Check your own letter, which may give you more.
Applies to All plan types, though the appeal clock is not the same for all of them — check the deadline block below. Most common on facial procedures and hair removal.
When your plan has a blanket exclusion for gender-affirming care
A blanket exclusion says the plan does not cover this category of care at all, regardless of medical necessity. That is a different fight from a medical-necessity denial: more documentation will not help, because the plan is not disputing your clinical need. What matters is whether the exclusion is lawful for your plan type.
Deadline. At least 180 days from RECEIPT to appeal internally, then four months from that decision to request external review. An exclusion is worth appealing even when it looks final.

Requesting a gap exception when no in-network surgeon can do your procedure
A gap exception, sometimes called a network exception, asks your plan to cover an out-of-network surgeon at in-network cost sharing because no in-network provider can actually perform your procedure. It is a network argument, not a medical-necessity argument, and it is one of the most under-used tools available.
Deadline. At least 180 days from RECEIPT to appeal. A gap-exception request is often faster than an appeal and can be made while the clock runs.
Applies to All plan types with a provider network, though the appeal clock differs — check the deadline block below. Names differ by insurer.
Appealing an "experimental or investigational" denial
An experimental or investigational denial claims the procedure is not established care. For gender-affirming surgery this is usually wrong on the evidence: the procedures are decades old, described in the standards of care, and Medicare's blanket experimental exclusion was struck down in 2014. Answer it with literature and the plan's own definition.
Deadline. At least 180 days from the day you RECEIVED the denial to appeal internally. Gathering evidence takes time, so start the appeal before you finish collecting it.
Applies to All plan types, though the appeal clock is not the same for all of them — check the deadline block below. Less common than it was, and usually weak when it appears.
Fixing a denial that is really a prior-authorization or paperwork problem
A procedural denial is not about your care at all. The claim was filed late, the authorization was missing or expired, the code was wrong, or the referral did not exist. These are the cheapest denials to fix and the easiest to lose, because the deadline runs while you assume it is a clinical dispute.
Deadline. The point of this page: the clock is running while you assume this is a clinical argument. A procedural denial starts the same appeal window a medical one does — at least 180 days from RECEIPT under 29 CFR 2560.503-1(h)(3)(i) — and it does not pause while you sort out whose paperwork failed.

When the denial applies a rule that is not in your plan
Insurers sometimes deny a claim using a test that does not appear in your plan document, most often by turning an availability question into a skills question. Find the provision the letter cites, read what it actually requires, and set the two standards side by side. That gap is the argument.
Deadline. None of its own. This argument goes inside your internal appeal, so the internal appeal deadline is the one that governs: at least 180 days from when you received the denial.
Applies to Any plan type, any denial that cites a plan provision. Strongest where the plan text and the letter's wording clearly differ.
