Appealing an Insurance Denial for Gender-Affirming Care
A denial is not the end of the road. It is often the beginning of an appeal you can win. This toolkit explains how appeals work, walks you through each step, and gives you a letter template you can copy and adapt.

Know This First
A Denial Is Not a Final Answer
Insurance companies deny claims for many reasons, and many of those denials are overturned on appeal. You have a legal right to appeal, and gender-affirming care is medically necessary treatment for gender dysphoria under the widely accepted WPATH Standards of Care. Persistence matters, and you do not have to do it alone.
Two Levels of Appeal
Most plans give you an internal appeal (reviewed by the insurance company) and, if that is denied, an external review by an independent third party whose decision the plan must honor. There are strict deadlines at each step, often 180 days from the denial to file, so act promptly and keep copies of everything.
Your Anti-Discrimination Protection
Section 1557 of the Affordable Care Act prohibits discrimination based on sex, which includes gender identity, in health programs that receive federal funding. A blanket exclusion of gender-affirming care, or treating it differently from comparable care, may violate it. This is a powerful point to raise in an appeal.
The Process
How to Appeal, Step by Step
1
Get the Denial in Writing
Request the written denial letter and the Explanation of Benefits. You need the exact reason for the denial and any codes cited. You cannot effectively appeal a reason you have not seen in writing.
2
Understand Why It Was Denied
Common reasons: the plan calls the care "not medically necessary," cites a blanket exclusion for transgender services, says it was out of network, or says prior authorization was missing. Each reason has a different counter. Read your plan's coverage policy, you are entitled to a copy.
3
Gather Your Evidence
The strongest appeals include a letter of medical necessity from your treating provider, relevant medical records, and references to the WPATH Standards of Care. If your provider can tie your treatment to accepted clinical standards, your case is much stronger.
4
File the Internal Appeal Before the Deadline
Submit your written appeal to the address in your denial letter, with your documentation, before the deadline (often 180 days). Send it so you have proof of delivery, and keep a full copy. Use the template below as your starting point.
5
Request an External Review If Denied
If the internal appeal is denied, request an external, independent review. An outside reviewer with no stake in the outcome decides, and the plan must follow that decision. Your denial letter must explain how to request it.
6
Escalate and Get Help
If your insurer is not cooperating, file a complaint with your state Department of Insurance (find yours through the NAIC directory below). For trans-specific denials, the Trans Health Project and Lambda Legal can help. You have more options than you may think.

Member: [Your Name] | ID: [Number] | Claim/Reference: [Number]
To the Appeals Department,
I am writing to formally appeal your denial dated [date] of coverage for
[service or procedure], which was denied for the stated reason of
"[reason given in the denial letter]." I request a full review and reversal
of this decision.
This care is medically necessary treatment for gender dysphoria, a recognized
medical condition. My treatment plan follows the World Professional Association
for Transgender Health (WPATH) Standards of Care, the accepted clinical standard.
My treating provider, [Provider Name], has determined this treatment is
medically necessary, and a signed letter of medical necessity is enclosed.
Denying medically necessary gender-affirming care may also conflict with Section
1557 of the Affordable Care Act, which prohibits discrimination on the basis of
sex, including gender identity, in covered health programs.
Enclosed with this appeal:
- Letter of medical necessity from my treating provider
- Relevant medical records
- [Any other supporting documents]
Please reverse this denial and approve coverage. If this internal appeal is
denied, I request written notice of my right to an external, independent review.
Thank you for your prompt attention to this appeal.
Sincerely,
[Your Name and Signature]
Ask Your Provider for the Letter of Medical Necessity
The provider's letter is the heart of your appeal. Ask your doctor or clinic to write one that states your diagnosis, the treatment, why it is medically necessary for you, and that it follows WPATH Standards of Care. Many clinics that serve trans patients do this routinely, just ask.
