How to Get Insurance to Cover Your Cranial Prosthesis (Medical Wig)

Restora · 9 min read · Updated August 2026

Short answer first: yes — insurance can cover a medical wig. A cranial prosthesis prescribed for hair loss from chemotherapy, alopecia, or other medical conditions is considered durable medical equipment (DME) under most plans, billed with CPT code A9282. The coverage is real — but the paperwork can be intimidating. This guide breaks the whole process into clear, actionable steps so you know exactly what to expect, what to gather, and what to do if you're denied.

What is a cranial prosthesis?

A cranial prosthesis is the medical term for a wig provided to a patient experiencing medically-related hair loss. Because it's prescribed by a physician to address a medical condition — not bought for cosmetic reasons — it qualifies as medically necessary equipment. That distinction is the entire basis for insurance coverage.

At Restora, every wig in our line (Abla, Charli, and Bree) is a medical-grade cranial prosthesis: 100% Mongolian Remy human hair, glueless lace-front construction, and comfort features designed for sensitive scalps. We document them as cranial prostheses, which is exactly what your insurer needs to see. If you're newer to this, our complete guide to chemo wigs is a good place to start.

Does insurance cover wigs?

Yes — when the wig is a medically prescribed cranial prosthesis. Here's the important nuance: a fashion wig purchased over the counter is not covered. A cranial prosthesis ordered through a medical supplier, with a prescription and proper coding, is treated like any other piece of DME — a wheelchair or a hospital bed — and covered under your DME benefit.

• Medicare covers cranial prostheses under Part B DME benefits when medically necessary.
• Medicaid coverage varies by state, but many states cover cranial prostheses with a prescription.
• Private insurance — most major plans cover cranial prostheses, though your specific policy's DME benefit, deductible, and coinsurance will apply.

The key takeaway: the word “wig” is cosmetic, but “cranial prosthesis” is medical. How the item is prescribed, coded, and billed determines whether your insurance says yes.

CPT code A9282, explained

Every medical item is identified by a code. The code for a cranial prosthesis is CPT/HCPCS A9282 (“cranial prosthesis, not otherwise specified”). Your supplier uses this code on the prior-authorization request and the claim you submit to insurance.

Getting the code right matters more than you'd think. A claim billed as a “wig” (a cosmetic item with no medical code) will be denied immediately. A claim billed correctly as A9282 with supporting documentation has a strong chance of approval. This is one of the most common — and most avoidable — reasons claims fail, and it's why working with a supplier who knows DME billing matters.

How the DME benefit works

Cranial prostheses fall under your plan's durable medical equipment benefit. Before you start, it helps to understand the pieces:

• Medical necessity. Your plan needs documentation that the prosthesis is medically necessary — usually a prescription and a brief note from your doctor.
• Deductible. You may need to meet your plan's annual deductible before coverage kicks in.
• Coinsurance. Plans typically pay a percentage (often 80%) of the allowed amount; you're responsible for the rest.
• In-network supplier. Some plans only cover prostheses from enrolled DME suppliers. Restora works with plans across Medicare, Medicaid, and private insurers to confirm your coverage before you commit.

The amount covered varies by plan, but many patients end up paying a fraction of retail — or nothing at all after their deductible.

How prior-authorization works

Many plans require prior-authorization (also called pre-certification or pre-approval) before they'll cover a cranial prosthesis. Here's how the process flows:

1. Get a prescription. Your oncologist or dermatologist writes a prescription for a cranial prosthesis, including your diagnosis (e.g., chemotherapy-induced alopecia).
2. Your supplier submits the request. The supplier sends the prior-authorization to your insurer with the prescription, CPT code A9282, and supporting documentation.
3. The insurer reviews. This typically takes a few days to a few weeks, depending on the plan.
4. Approval. Once approved, the prosthesis can be ordered, and the claim is submitted after delivery.

This is exactly the process we automate at Restora — our Insurance Concierge prepares the prior-authorization, applies the correct CPT coding, submits the claim, and tracks it through to resolution.

What documentation do you need?

Having the right paperwork ready can be the difference between a smooth approval and a denial. Here's the checklist:

• Prescription from your oncologist or dermatologist — stating the diagnosis and that a cranial prosthesis is medically necessary.
• Diagnosis documentation — e.g., chemotherapy-induced alopecia, alopecia areata/totalis, or other medical hair loss.
• Letter of medical necessity — some plans request a short letter from your doctor explaining why the prosthesis is needed (many have a template).
• Your insurance information — member ID, group number, and plan documents.
• Photos (optional but helpful) — pre-loss hair photos for color matching; some plans also accept photos documenting the hair loss.

How Restora's Insurance Concierge handles it

We built our Insurance Concierge service because the paperwork shouldn't be your job. For a one-time fee of $49, our team handles the entire administrative side:

• Prior-authorization preparation and submission
• Correct CPT coding (A9282) on all documentation
• Claim submission and tracking
• Follow-up with your insurer on your behalf
• Guidance on any additional documentation your plan requests

You add it to any purchase during checkout. Most patients tell us it's the best $49 they've spent — it turns a weeks-long, confusing process into a handled one.

Common denials — and how to appeal

Even with everything done right, denials happen. The good news: most denials are reversible. Here are the common reasons and what to do:

• “Not medically necessary.” Usually fixed by adding a letter of medical necessity from your doctor. This is the most common and most fixable denial.
• “Cosmetic item, not covered.” Usually a coding problem — the claim was filed as a wig rather than as a cranial prosthesis (A9282). Resubmission with correct coding often resolves it.
• Missing documentation. The insurer didn't receive the prescription or diagnosis codes. Resubmit with the complete package.
• Out-of-network supplier. If your plan requires an in-network DME supplier, we help you confirm network status before purchase to avoid this entirely.

How to appeal a denial

1. Read the denial letter carefully — it states the exact reason and your appeal rights.
2. Note the deadline. Appeals usually have a strict window (often 30–180 days). Don't wait.
3. Request a formal redetermination (level 1 appeal) with your insurer, attaching any missing documentation.
4. If still denied, request a reconsideration (level 2 appeal) with an independent reviewer.
5. As a last resort, request external review by a state or independent panel — your denial letter explains how.

If you're denied, don't give up — and don't go it alone. Our team appeals denials as part of the Insurance Concierge service, and we've seen many denials overturned on appeal.
