If you want insurance to cover your medical wig, you'll need a prescription from your doctor.
This is one of the most important steps in the process — without it, your insurance claim will likely be denied.
The good news is that getting a prescription for a cranial prosthesis is usually straightforward once you know what to ask for and who to ask. Here's everything you need to know to walk into your appointment prepared.
Which Doctors Can Write a Prescription for a Cranial Prosthesis?
Any licensed physician can write a prescription for a cranial prosthesis, but it's most effective when the prescription comes from the doctor treating your underlying condition.
The most common prescribing physicians include:
Dermatologists — If your hair loss is caused by alopecia areata, scarring alopecia, lichen planopilaris, frontal fibrosing alopecia, or other scalp and hair conditions, your dermatologist is the ideal prescriber. They can document your diagnosis, the extent of hair loss, and why a cranial prosthesis is medically appropriate.
Oncologists — If you're undergoing chemotherapy or radiation and experiencing treatment-related hair loss, your oncologist can write the prescription. They understand the timeline of hair loss during treatment and can speak to the psychological impact on patients.
Primary Care Physicians — Your PCP or family doctor can write a cranial prosthesis prescription for most conditions, especially if they've been managing your care or can access your medical records showing the diagnosis. This is often the most accessible option.
Endocrinologists — If your hair loss is related to thyroid disorders or other hormonal conditions, your endocrinologist can provide the prescription along with documentation of your diagnosis.
Rheumatologists — For hair loss related to autoimmune conditions like lupus, your rheumatologist may be the appropriate prescriber.
Psychiatrists or Psychologists — For trichotillomania (hair-pulling disorder), a mental health provider who has diagnosed and is treating the condition can provide documentation, though you may still need an MD to write the actual prescription depending on your state's regulations.
The key is that the prescribing doctor should have direct knowledge of your condition and be able to document it in your medical records.
What Should the Prescription Include?
A proper cranial prosthesis prescription needs specific elements to be accepted by insurance.
Make sure your prescription includes:
The words "cranial prosthesis" or "cranial hair prosthesis." This is critical. If the prescription says "wig," insurance will deny it as cosmetic. The terminology must reflect the medical device classification.
Your diagnosis. The prescription should state the medical condition causing your hair loss, using the appropriate medical terminology (for example, "alopecia areata" rather than just "hair loss").
A statement of medical necessity. Even a brief statement like "medically necessary for treatment of [condition]" strengthens the prescription.
The doctor's information. The prescription must include the physician's name, credentials, practice address, phone number, and signature. A printed prescription on office letterhead is ideal.
Date. The prescription should be current. Some insurance companies won't accept prescriptions older than 6-12 months.
NPI number. Some insurance companies require the physician's National Provider Identifier number on the prescription.
Here's an example of what a complete prescription might look like:
"Cranial prosthesis (cranial hair prosthesis) prescribed for [Patient Name] for treatment of alopecia areata. This device is medically necessary due to significant hair loss affecting the patient's psychological wellbeing and daily functioning."
How to Talk to Your Doctor About It
Some patients feel awkward asking their doctor for a wig prescription, but there's no reason to be.
Doctors write these prescriptions regularly, and most are happy to help once they understand what you need.
Here's how to approach the conversation:
Be direct about what you need. You can say something like: "I'd like to get a cranial prosthesis to help with my hair loss, and I'm hoping my insurance will cover it. I need a prescription that specifically says 'cranial prosthesis' — can you help me with that?"
Explain why you're asking. Let your doctor know that the terminology matters for insurance purposes. Many doctors aren't familiar with medical wig billing and may not realize that writing "wig" instead of "cranial prosthesis" will result in a denial.
Bring a sample prescription. If you're working with a Cranial Prosthesis Specialist, they may be able to provide a template or sample prescription for your doctor to reference. This makes it easier for the doctor and ensures nothing is left out.
Mention the Letter of Medical Necessity. In addition to the prescription, you'll likely need a Letter of Medical Necessity (LMN) for insurance approval. Ask your doctor if they can provide both at the same appointment. The LMN goes into more detail about your condition and why a cranial prosthesis is appropriate treatment.
Be prepared to explain the impact. If your doctor seems hesitant, be honest about how hair loss affects you. The psychological impact of medical hair loss — including anxiety, depression, social withdrawal, and reduced quality of life — is well-documented and is a legitimate medical reason for prescribing a cranial prosthesis.
What If Your Doctor Says No?
It's rare, but occasionally a doctor may be reluctant to write a cranial prosthesis prescription.
This usually happens when:
- The doctor isn't familiar with cranial prostheses and doesn't realize they're a legitimate medical device
- The doctor doesn't feel qualified to prescribe for a condition outside their specialty
- The doctor's practice has a policy against writing prescriptions for durable medical equipment
If your doctor declines, you have options:
Ask for a referral. If your primary care doctor isn't comfortable prescribing, ask for a referral to a dermatologist who can evaluate your hair loss and provide the prescription.
See a different provider. You're not limited to one doctor. A dermatologist who specializes in hair loss conditions will be very familiar with cranial prosthesis prescriptions and can often see you for a single consultation visit.
Work with your Cranial Prosthesis Specialist. Many CPS providers have relationships with physicians who understand the prescription process and can help facilitate the documentation you need.
Educate your doctor. Sometimes doctors simply don't know about medical wig coverage. You can share information about cranial prostheses as durable medical equipment and how insurance covers wigs. Once they understand, many doctors are willing to help.
The Letter of Medical Necessity: Your Secret Weapon
While the prescription gets your foot in the door, the Letter of Medical Necessity (LMN) often determines whether your claim gets approved.
This letter provides the detailed medical justification that insurance companies require.
A strong LMN should include:
- Your diagnosis and how it was determined
- The extent and progression of your hair loss
- How hair loss impacts your daily life, mental health, and functioning
- Why a cranial prosthesis is medically appropriate (not just cosmetic)
- The doctor's recommendation that a cranial prosthesis is part of your treatment plan
Some doctors have templates for these letters. Others may need you to provide guidance on what to include. Your Cranial Prosthesis Specialist can often help by providing a sample LMN or outline for your doctor.
How Long Is a Prescription Valid?
Most insurance companies accept prescriptions that are less than 12 months old, though some may require a more recent prescription (within 6 months).
If you're not ready to order your cranial prosthesis immediately, check with your insurance or provider about timing requirements.
Keep in mind that you may need a new prescription for future cranial prostheses. Most insurance plans that cover cranial prostheses allow a new one every 6-12 months, but each claim typically requires a current prescription.
Getting Your Prescription: Step by Step
Here's a simple action plan:
Step 1: Identify the right doctor to ask — ideally the physician treating your hair loss condition.
Step 2: Schedule an appointment. If you have an upcoming visit already, add this to your list of things to discuss. Otherwise, call and explain you need a prescription for a cranial prosthesis.
Step 3: At the appointment, be clear about what you need: a prescription that says "cranial prosthesis" with your diagnosis and a statement of medical necessity.
Step 4: Ask about a Letter of Medical Necessity at the same time.
Step 5: Get the prescription on office letterhead with all required information (doctor's name, credentials, address, phone, NPI, signature, date).
Step 6: Bring your prescription to your Cranial Prosthesis Specialist, who can help with the next steps of insurance verification and claims submission.
