Quick answer: Any licensed physician involved in your care — your oncologist, dermatologist, or primary care doctor — can write a prescription for a cranial prosthesis. Simply ask at your next appointment: "Could you write me a prescription for a cranial prosthesis for my hair loss?" Make sure it says cranial prosthesis (not "wig") and includes your diagnosis. Doctors write these routinely; it takes about a minute.
Exactly what to say
"My hair loss is from [my treatment / my condition], and I'm looking into a cranial prosthesis. My insurance may consider reimbursement with a prescription. Could you write one that says 'cranial prosthesis' and includes my diagnosis?" That's the whole conversation. If it feels awkward, remember: your physician has been asked this many times, and supporting your wellbeing through treatment is part of their job.
What the prescription should include
The words "cranial prosthesis" (some insurers also accept "cranial hair prosthesis" or "hair prosthesis") · your diagnosis or the medical cause of hair loss · the date · the physician's signature and information. If your insurer requires a diagnosis code on claims, the office can include it.
Prescription vs. Letter of Medical Necessity
Some plans want a prescription alone; others also ask for a short Letter of Medical Necessity explaining the medical need. Ask your insurer which they require before your appointment so one visit covers everything. ANIOR Medical includes an LMN template your physician can adapt in minutes with every prosthesis purchase.

Timing tip
If you're beginning chemotherapy, ask during a pre-treatment visit — you're already there, and having the prescription in hand means your paperwork is done before your first infusion. Chemo timing guide →
