Insurance & Medical Wigs

How to Get a Prescription for a Cranial Prosthesis

A guide for patients, and for the physicians who prescribe. Print Part Two and hand it to your doctor.

Most denied claims for medical human hair wigs are not denied because the patient was ineligible. They are denied because of a word, a missing code, or a date.

This guide fixes that. The first half is for patients. The second half is written so your doctor can read it in ninety seconds and write a prescription that clears utilization review on the first pass. Both templates are copy and paste ready.

The one word that gets claims denied

Insurance plans almost universally list wigs under cosmetic exclusions. The same physical item, when prescribed for medically documented hair loss, is a cranial prosthesis, and cranial prostheses fall under prosthetic or durable medical equipment benefits.

This is not a workaround. It is the correct clinical and billing term for a hair prosthesis worn to manage the consequences of a diagnosed medical condition. Using it is simply accurate.

If the word "wig" appears anywhere in the documentation, expect a cosmetic denial. For the wider picture on benefits, caps and what carriers typically approve, read our complete guide to cranial prosthesis insurance coverage.

Part One: For patients

Step 1. Call your insurer before your appointment

Ten minutes on the phone now prevents a two month appeal later. Ask for member services and read these out loud.

1. Does my plan cover a cranial prosthesis? Please check under prosthetics and under durable medical equipment, not under wigs.
2. Which HCPCS code does my plan process it under: A9282, S8095, or L8499?
3. Is prior authorization required before purchase?
4. Is there a dollar cap, and how often is the benefit available? Once per twelve months? Per lifetime?
5. Does the supplier need to be in network or hold an NPI, or will you reimburse me directly for an out of network purchase?
6. Which claim form do I submit, and what is the filing deadline from the date of purchase?
7. Does my plan cover a second unit for hygiene or rotation?

Step 2. Get the prescription dated before you buy

Step 3. Bring your doctor the language

Your physician wants to help you. They may simply have never written this particular prescription before, and the difference between an approved and a denied claim is wording they were never taught.

Print Part Two of this page and bring it with you. A simple way to open the conversation:

"My hair loss is affecting my daily life. I am buying a cranial prosthesis, and my insurance will only process it if the prescription uses that exact term and includes specific ICD-10 and HCPCS codes. I brought a one page reference with everything you need."

Step 4. Assemble the claim packet

A complete packet is difficult to deny. Submit all of it together:

• The prescription, signed and dated, with the prescriber's NPI
• The letter of medical necessity
• The itemized invoice from your provider, showing the HCPCS code, diagnosis code, tax ID and NPI
• Proof of payment
• Your insurer's claim form, fully completed
• A short personal impact statement in your own words
• A photograph documenting your hair loss

The impact statement and the photograph are optional, but they matter. Reviewers are people, and a clear record of functional and psychological impact is much harder to file under cosmetic.

Step 5. If you are denied, appeal

A first level denial is not the end. It is often the start. Denials are frequently automated and frequently reversed once the documentation gap is closed.

Your appeal should name the specific reason given for the denial and answer that reason directly. If the denial says cosmetic, your appeal cites the diagnosis code, the functional indications, and the prescribing physician's attestation. If the first appeal fails, request a peer to peer review with a physician reviewer.

The ten elements payers look for

A prescription containing all ten of these clears most utilization review on the first pass.

1. Patient identifiers. Full name, date of birth, insurance member ID.
2. Date of the order. Must precede the date of purchase.
3. The term "cranial prosthesis." Not "wig," anywhere in the document.
4. Specific ICD-10 diagnosis. Coded to the highest available specificity. "Alopecia" alone is not a diagnosis.
5. HCPCS code. A9282, S8095, or L8499, matched to the item and to the plan.
6. Etiology and clinical narrative. Onset, extent, cause, and whether the loss is temporary or permanent.
7. Statement of medical necessity. The functional indications, stated affirmatively.
8. Quantity and frequency. For example, one cranial prosthesis, replacement no more than once per twelve months.
9. Duration of need. Twelve months, twenty four months, or lifetime.
10. Prescriber block. Printed name, credentials, NPI, practice address, phone, signature, date.

ICD-10 diagnosis codes

Code to the highest specificity supported by your examination. Codes update annually on October 1. A patient overview of these conditions is in our article on the different types of alopecia.

Alopecia areata spectrum

Nonscarring hair loss

Scarring and cicatricial alopecia

Treatment related and drug induced

Other qualifying etiologies

Note that androgenetic alopecia without an underlying systemic cause, coded L64.8 or L64.9, is almost never approved. Payers classify pattern hair loss as cosmetic. If a systemic driver exists, code the driver.

HCPCS codes

Language that establishes medical necessity

Payers distinguish cosmetic from medical on the basis of stated function. Include the indications that apply to your patient:

• Protection of an exposed scalp from ultraviolet radiation and actinic damage, particularly in patients with prior radiation exposure or photosensitizing therapy
• Thermal regulation and protection against heat loss and cold exposure over an unprotected scalp
• Protection of compromised or irradiated scalp skin from mechanical trauma
• Management of the documented psychological sequelae of medical hair loss, including impact on treatment adherence, social functioning and return to work
• Support of the patient's overall course of treatment for the underlying diagnosed condition

Template 1: The prescription

Copy onto practice letterhead. Bracketed fields are for the prescriber to complete.

Template 2: Letter of medical necessity

Most plans want this in addition to the prescription. Copy onto practice letterhead.

The ten most common reasons claims are denied

What is not true

There is a great deal of inaccurate information published on this topic, some of it on other providers' websites. Correcting it here so that nobody walks into an appointment or a phone call with a false expectation.

Original Medicare does not cover cranial prostheses. Some Medicare Advantage plans include a supplemental benefit. Check the specific plan documents.

Medicaid generally does not cover them.

TRICARE and VA coverage is limited. Both cover one unit per lifetime of the beneficiary, for hair loss occurring due to cancer treatment.

Some states do have mandates, and some do not. Connecticut, Rhode Island, Maryland and several others have enacted statutes addressing scalp or hair prosthesis coverage. Requirements and dollar limits vary considerably. Even where a mandate exists, self funded employer plans regulated under ERISA can be exempt from state insurance mandates, which means the law in your state may not apply to your particular plan. Ask your plan directly whether it is fully insured or self funded.

If your plan will not cover it

Coverage denial is not the end of the financial conversation.

FSA and HSA

A cranial prosthesis prescribed for medical hair loss is generally an eligible expense with a letter of medical necessity on file. Use your FSA or HSA card at the point of purchase and retain the documentation. Full detail in our guide to using an FSA or HSA for a human hair wig.

Tax deduction

IRS Publication 502 treats a wig purchased on the advice of a physician for a patient who has lost hair from disease as a deductible medical expense, to the extent total medical expenses exceed 7.5 percent of adjusted gross income. We cover the specifics in writing off a medical wig on your taxes. Speak with your tax preparer.

Employer benefit negotiation

If your employer sponsors a self funded plan, the benefits department has discretion to add the coverage at renewal. It costs nothing to ask.

Questions we get asked

Which doctor should write the prescription?

Any licensed physician treating you for the underlying condition. Oncologists, dermatologists, endocrinologists, rheumatologists and primary care physicians all write these. Your dermatologist is often the most familiar with the coding.

Can a nurse practitioner or physician assistant write it?

In most cases yes, provided they hold an NPI and are practicing within their state scope. Confirm with the plan.

How long is a prescription valid?

Typically twelve months from the date written, though this varies by plan. If yours is older than a year, request a fresh one.

My hair loss is temporary. Do I still qualify?

Yes. Chemotherapy induced hair loss is temporary and is one of the most commonly approved indications. The prescription should state that the loss is temporary and give an expected duration.

Will insurance cover a custom human hair prosthesis, or only a synthetic one?

It depends on the plan and on the dollar cap. Many plans reimburse a fixed amount regardless of the piece selected, which you can apply toward a custom human hair prosthesis and pay the difference. Ask about the cap, not about the material. Our honest guide to what a custom human hair wig costs explains what drives the price.

Do I need to buy from an in network provider?

Some plans require it, many do not and will reimburse you directly. Question five in Step 1 settles this.

What if I already bought my prosthesis?

Submit anyway. Some plans reimburse retroactively. If the denial is based on the purchase preceding the prescription, that is a specific, documented denial reason you can address in an appeal with a physician letter confirming the clinical need existed at the time of purchase.

How do I know what size and length to ask for?

Start with our cap size and head measuring guide, and if total hair loss means a standard cap will not sit securely, look at our large cap human hair wigs. If you still have partial coverage, a hair topper may be the better piece.
