Quick answer: Often, yes. A cranial prosthesis purchased because of hair loss from a medical condition or treatment is frequently an eligible HSA or FSA expense — typically when supported by a physician's prescription or Letter of Medical Necessity. Requirements vary by plan administrator, so confirm yours before purchasing, and keep your documentation with your records.
Why documentation matters
HSA/FSA rules distinguish medical expenses from cosmetic ones. A wig bought for style is cosmetic; a cranial prosthesis prescribed for medically-caused hair loss is a different category. The prescription or LMN is what establishes that difference on paper — get it before or at the time of purchase, and keep it in case your administrator asks for substantiation.
How to check your plan (two minutes)
Ask your HSA/FSA administrator: "Is a cranial prosthesis for medical hair loss an eligible expense, and do you require a prescription or Letter of Medical Necessity?" Also ask whether you can pay directly with your benefits card or should pay out of pocket and submit for reimbursement with your itemized receipt.
