If you've just been told you need a "prescription" for a wig, that sentence probably sounded strange. A prescription — for hair? Let me tell you what I tell every new client who asks me this in the showroom. It isn't complicated once you know what to ask for and who to ask. It's just a conversation most people have never had to have before.
Quick answer: Ask the doctor treating your hair-loss condition to write a prescription for a "cranial prosthesis" — not a "wig" — with an ICD-10 diagnosis code attached. Pair it with a short letter of medical necessity. Naming the correct term yourself is often what decides whether insurance takes your paperwork seriously later.
Why the Prescription Matters More Than People Expect
A lot of my clients assume the prescription is a formality. It isn't — it's the foundation of everything that comes after. Want to submit an insurance claim, use FSA or HSA funds, or appeal a denial? The prescription is the document everyone refers back to. Get it right at the start, and every step downstream is easier. Get it wrong — or skip it — and you're stuck fixing paperwork after the fact. I see that far more often than I'd like.
In my 25 years of fitting wigs, I've noticed a clear pattern. Clients who walk in with the right prescription almost always have a smoother path to reimbursement. The ones who bought a wig first and asked questions later usually don't. I explain the full claims process on my medical wigs page, but it all starts with this one document.
Which Doctor to Ask
You don't need a specialist in "wigs" — you need the doctor treating whatever is causing your hair loss. That's usually one of these:
- Oncologist — for hair loss from chemotherapy or radiation
- Dermatologist — for alopecia areata, alopecia totalis, or scarring alopecia
- Endocrinologist — for thyroid-related hair loss
- Primary care physician — if no specialist is involved yet, or as a starting point
Any licensed physician can technically write the prescription. But I encourage clients to ask the doctor most connected to their diagnosis. Their notes already document the medical reasoning. That makes the diagnosis code line up cleanly with your chart — and consistency matters if your claim is ever reviewed.
Exactly What to Say — a Script You Can Use
This is the part that trips people up the most, so let me give you the actual words. At your appointment, say this:
"Can you write me a prescription for a cranial prosthesis, along with a letter of medical necessity? My insurance requires that specific term — not the word 'wig.'"
That's it. You don't need to over-explain or apologize for asking. I've sat with hundreds of women through this exact moment. The ones who name the term directly almost always get a better result. Saying "I need something for a wig" leaves room for a busy office to write a prescription that just says "wig" — the one word that gets claims denied.
What Your Prescription Needs to Include
Not every prescription will hold up with an insurer. Here's what I check with every client before she leaves my showroom with paperwork in hand. The same details matter for FSA and HSA claims too — I cover those on my insurance and FSA/HSA page.
Quick Reference
What Belongs on a Wig Prescription
| Field | What It Should Say | Why It Matters |
|---|---|---|
| Terminology | "Cranial prosthesis" "Wig" | Insurers process claims by billing language — "wig" is read as cosmetic and denied |
| Diagnosis Code | ICD-10 code for your condition | Ties the prescription to a documented medical reason for hair loss |
| Signature & Date | Physician signed and dated | Undated or unsigned prescriptions are routinely rejected on first submission |
| Supporting Letter | Letter of medical necessity attached | Explains why the cranial prosthesis is needed — strengthens claims and appeals |
What If Your Doctor Has Never Written One Before
This happens more than you'd think, especially outside of oncology. Dermatologists and primary care doctors sometimes haven't fielded this request before. Most patients simply don't know to ask by name. If your doctor pauses or looks unsure, that doesn't mean no. It usually just means they need a starting point.
I keep a folder of sample letters of medical necessity in my showroom for exactly this reason. When a client's doctor isn't familiar with the process, I hand her a template to bring back to the office. I include the specific terminology and the HCPCS code A9282 that most insurers look for. Once a doctor sees the language they need, writing it takes a few minutes.
I had a client last month who was newly diagnosed with alopecia areata. Her dermatologist had genuinely never fielded this request before. She came back to my showroom a little discouraged after her first appointment. So we talked through exactly what to say on her follow-up call. She left a message with the office using the cranial prosthesis wording directly. The prescription was ready two days later — the office just hadn't known what she needed until she named it.
When to Ask — Don't Wait Until You're Shopping
If you can, bring this up at the appointment where your diagnosis or treatment plan is discussed. Don't wait until you're standing in a wig showroom, trying to explain your situation from memory. An early request gives the office time to prepare the paperwork without a rush. And you won't be scrambling for a prescription after you've already found a piece you love.
If you're newly diagnosed and everything feels like too much at once, it's fine to wait a week or two. This isn't a step you need to take the same day as difficult news. Just don't let it slip past your next few appointments.
How I Help Clients Through This Part
I work with Mount Sinai's oncology team to fit medical wigs. That means I've sat with hundreds of women navigating this exact conversation with their doctors — often on the same day they're absorbing a diagnosis. When a client comes to my Fort Lauderdale showroom without a prescription yet, I walk her through exactly what to ask for. Then I hand her a sample letter to bring to her doctor. Clients drive in from as far as Boca Raton and Miami Beach for this kind of help. Most wig sellers won't sit with you through the paperwork — I do.
Frequently Asked Questions
Do I need a prescription to buy a medical wig? Not to purchase one. But you do need one for any chance at insurance or FSA/HSA reimbursement. The prescription is what turns a wig into a "cranial prosthesis" in the eyes of your insurer.
Which doctor should I ask for a wig prescription? Whichever physician is treating the condition causing your hair loss — usually an oncologist, dermatologist, or endocrinologist. Any licensed physician can write it. The treating specialist's diagnosis code carries the most weight.
What exactly should I say to my doctor? Ask directly: "Can you write me a prescription for a cranial prosthesis, along with a letter of medical necessity?" Naming the term yourself keeps the office from defaulting to the word "wig."
What should be on the prescription? "Cranial prosthesis" (not "wig"), an ICD-10 diagnosis code, and a signature with date. Ideally, a letter of medical necessity comes attached.
What if my doctor has never written one before? It's common. Bring a sample letter of medical necessity and mention the HCPCS code A9282. Most doctors can adapt a template once they know what's required.
