Many major insurance companies cover cranial prostheses, but coverage depends heavily on your specific plan, your state, and the medical condition causing your hair loss. There is no universal rule. Some plans cover the full cost, others reimburse a fixed amount (often around $350), and some exclude wigs entirely. The key to getting coverage is understanding what your plan offers, getting the right documentation, and using precise medical terminology throughout the process.
Which Insurers Offer Coverage
Blue Cross Blue Shield, Aetna, Cigna, and UnitedHealthcare all have plans that can cover cranial prostheses, but “can” is the operative word. Coverage varies not just between insurers but between individual plans within the same insurer. A Blue Cross plan in Vermont, for example, considers a wig medically necessary when generalized hair loss results from chemotherapy, radiation therapy, scalp injury, third-degree burns, alopecia totalis, alopecia areata, or congenital baldness present since birth. A Blue Cross plan in another state may have a completely different list or no coverage at all.
Cigna’s prosthetic device policy covers external replacements for missing body parts but does not explicitly list cranial prostheses as a named category. That doesn’t mean your Cigna plan won’t cover one, but it does mean you’ll need to call the number on your card and ask specifically. The same is true for most large insurers: the corporate policy sets a framework, but your employer’s benefit plan or your individual contract determines what’s actually covered.
If you receive benefits through an Administrative Services Only (ASO) arrangement, where your employer self-funds the plan and the insurer just administers it, your coverage may differ from what the insurer’s standard policies say. In that case, your employer’s benefit plan documents are the final word.
State Laws That Require Coverage
A handful of states have passed laws mandating that insurers cover cranial prostheses, though the details vary significantly. Massachusetts requires all insurance companies to cover cranial prostheses at a $350 annual maximum, but only for hair loss caused by cancer or leukemia. Minnesota also mandates coverage at a $350 annual maximum, but specifically for hair loss due to alopecia areata.
Other states have their own mandates or are considering legislation, but coverage requirements are far from uniform across the country. Even in states with mandates, not all groups are required to follow state legislative requirements. Self-funded employer plans regulated under federal law (ERISA) can be exempt from state insurance mandates, which means the law in your state may not apply to your particular plan.
Medical Conditions That Qualify
When insurers do provide coverage, they typically limit it to hair loss caused by specific medical conditions. The most commonly accepted reasons include:
- Chemotherapy or radiation therapy for cancer treatment
- Alopecia areata, totalis, or universalis (autoimmune hair loss)
- Scalp injuries or third-degree burns
- Congenital baldness present from birth
Pattern baldness (androgenetic alopecia) is almost never covered, as insurers classify it as a cosmetic concern. Hair loss from trichotillomania or other conditions may or may not qualify depending on your plan. The first step is always to check your specific policy language.
Medicare and Medicaid
Traditional Medicare does not currently cover wigs or cranial prostheses. Medicare generally classifies them as cosmetic items rather than medical devices. Some Medicare Advantage plans offered by private insurers may include wig coverage as a supplemental benefit, but this is plan-specific and not part of standard Medicare Part B.
Medicaid coverage varies by state. Some state Medicaid programs cover cranial prostheses for qualifying conditions, while others do not. Contact your state’s Medicaid office directly to find out what’s available.
Why the Words on Your Paperwork Matter
One of the most common reasons claims get denied is language. The item on every piece of documentation should be called a “cranial prosthesis,” never a “wig.” Insurance companies process claims based on medical coding, and the word “wig” signals a cosmetic product rather than a medically necessary device.
To file a successful claim, you need a prescription from your dermatologist or treating physician. That prescription should include your diagnosis, the recommended treatment listed as a cranial prosthesis, the appropriate diagnosis code (for alopecia areata, these are ICD codes like L63.0 for alopecia totalis or L63.1 for alopecia universalis), the provider’s NPI number, and the physician’s signature.
Your receipt from the wig retailer also needs to use the right terminology. It should list the product as a “cranial prosthesis” with the price, the retailer’s Tax ID number, and the HCPCS code A9282, which is the standard billing code for this item. If your retailer has an NPI number as a covered cranial prosthesis provider, include that too.
How the Claims Process Works
Unlike most medical expenses, cranial prostheses typically require you to pay upfront and then submit a claim for reimbursement. You won’t hand over an insurance card at checkout. Instead, you’ll buy the prosthesis out of pocket, gather your documentation, and file a claim with your insurer afterward. The insurer then decides how much to reimburse you, if anything.
Before you buy, call your insurance company and ask specifically whether your plan covers cranial prostheses, what conditions qualify, what documentation they require, and whether there’s a dollar cap on reimbursement. Get the representative’s name and a reference number for the call. Then follow these steps:
- Get your prescription from a dermatologist or specialist with all required codes and signatures
- Buy from a retailer who can provide a medical invoice using the term “cranial prosthesis” and the correct HCPCS code
- Submit your claim with the prescription, the medical invoice, and any other documents your insurer requested
- Track everything in a log: dates, representative names, reference numbers, documents sent, and how you sent them
Follow up regularly until you get a definitive approval or denial. If your claim is denied, you have the right to appeal. A denial letter will include instructions for the appeals process, and having detailed records of every interaction strengthens your case.
Help When Insurance Falls Short
If your insurance denies coverage or you don’t have insurance, several organizations provide free or discounted wigs. The American Cancer Society operates wig banks across the country that offer free wigs to people with cancer. Children with Hair Loss provides free hair replacements, care kits, and styling services to anyone under 21 with medically related hair loss. Wigs for Kids offers free wigs to children whose families meet financial eligibility criteria.
The organization After Breast Cancer Diagnosis provides wigs specifically to women diagnosed with breast cancer who have no insurance or limited financial resources. Wigs and Wishes distributes free wigs to cancer patients through participating salons nationwide. Many hospitals also maintain their own wig banks or can connect you with local resources. Ask your treatment center’s social worker, as they often know about programs specific to your area that aren’t widely advertised.
For patients with alopecia areata specifically, the National Alopecia Areata Foundation maintains a detailed guide to insurance reimbursement and can help you navigate the claims process. Even when your plan technically offers coverage, the reimbursement amount may not come close to the actual cost of a quality cranial prosthesis, so combining partial insurance reimbursement with assistance programs can help bridge the gap.
