What is a Cranial Prosthesis?

The term cranial prosthesis (“hair prosthesis”, or “medical wig”) is used to describe a custom-made wig that is designed for patients who have lost their hair due to medical conditions such as Alopecia Areata, Alopecia Totalis, Trichotillomania and Chemotherapy.

Cranial hair prostheses are different from regular wigs.  The procedure of making a cranial hair prosthesis involves several steps, including measuring the perimeter of the head mold to ensure a perfect fit.  Molds are also made at the base of the head to ensure the wig fits properly.  People who suffer from chemotherapy tend to be sensitive to materials and their scalp is susceptible to allergies, so the base is made of hypoallergenic lace or fabric foundation.

Additionally, the base of human hair is ventilated so that the knotting does not touch the scalp.  You may use the silk top ventilation method or simply coat the underside with wig poly to accomplish this.

Benefits of a Prosthesis

  • Breathable/Ventilated
  • Covered by many insurance companies
  • Natural-looking hairline
  • No Slippage
  • Comfortable around the ears
  • Lasts up to 2+ years with proper maintenance
  • The unit is made with human hair!  Treat it as your own.  It can be dyed, shampooed, conditioned, straightened, and curled.

Did you know that there are multiple wig cap variations and foundation combinations that can be used to create your cranial prosthesis?

You should know that insurance companies set their own policies when it comes to accepting insurance payments for medical wigs. Moreover, different plans under the same insurance company will have different limits and exclusions, so it is very important that you understand that the process may vary from claim to claim. As a result, most of the time, the process will follow a pretty standard pattern. You just need to know what information to ask for, what forms to look for, and who to contact if you need help.

Here are the preliminary steps to follow before filing a claim:

Step #1 – Obtain Insurance Verification

Step #2 – Secure a Prescription

Step #3 – Schedule a Consultation

Step #4 – Place an Order

Filing a Claim

Filing a claim for a medical wig or cranial prosthesis can be challenging if you are not experienced with the process. It is critical that you obtain the relevant information from your client and submit the claim with the proper wording and codes. In addition to these items, your client should also include a letter describing how hair loss has affected them. Include any emotional impact on daily life and things that have happened because of the condition.
