If you've just been told you need a cranial prosthesis — the medical term for a wig worn for hair loss related to illness or treatment — one of the first questions is often practical: does insurance cover medical wigs? The short answer is that it can, but it depends on your plan, your documentation, and how you ask. This guide walks you through the process in plain language, so you know exactly what to gather, what to say, and what to do if your first claim is denied.
Start with the Right Language: Cranial Prosthesis
Insurers don't search for the word "wig." They search for cranial prosthesis. Using the correct terminology from the start makes a real difference in how your request is processed.
When you and your supplier refer to the piece as a medical device — a cranial prosthesis fitted for hair loss due to a diagnosed condition — it enters a different conversation than a cosmetic hairpiece.
What Insurers Typically Require
Coverage isn't automatic, but the requirements are usually the same. Plan to provide:
- A doctor's prescription or order for a cranial prosthesis
- A medical necessity letter explaining the diagnosis and why the prosthesis is needed
- Documentation of diagnosis, such as a treatment plan or pathology report
- A claim form from the supplier, often with a billing code
The most commonly cited code is CPT A9282 (cranial prosthesis), though your supplier or insurer may use a related HCPCS code. Ask which code they expect before you submit.
Filing the Claim: Step by Step
- Call your insurer's customer service and ask about "cranial prosthesis coverage" specifically
- Confirm whether they cover, how much (a dollar cap or a percentage), and the deductible
- Ask whether you pay upfront and receive reimbursement, or whether there is a preferred supplier who bills directly
- Submit the prescription, letter, documentation, and itemized receipt together
- Keep copies of everything, and note the date and name of anyone you speak with
Reimbursement vs. Direct Coverage
These two models feel very different in practice:
- Direct coverage means your insurer pays a contracted supplier, and you owe less upfront
- Reimbursement means you pay for the piece and then submit a claim to get money back
With reimbursement, ask about the deadline for filing — many plans require claims within 90 days to a year.
What to Do If Your Claim Is Denied
A denial is not the end of the road. Most plans have an appeal process, and a surprising number of appeals succeed.
- Request the denial letter in writing and read why it was denied
- Ask your oncology social worker or patient navigator to help you write the appeal
- Add a letter from your doctor that directly addresses the reason for denial
- Keep escalating through each appeal level, and document everything

Advocating for yourself is exhausting, and it is also reasonable. You are asking for something that supports your treatment and dignity.
