Does FSA cover Botox?
Cosmetic Botox for wrinkles isn't a qualified FSA expense, but Botox prescribed to treat a diagnosed condition like chronic migraine or hyperhidrosis can qualify with documentation.
What flips the answer
- Covered when
A physician prescribes Botox for a diagnosed condition (chronic migraine, hyperhidrosis, muscle spasticity) and documents it with a Letter of Medical Necessity.
- Not covered when
The Botox is cosmetic — for wrinkles or appearance — with no medical diagnosis.
- Not covered when
You can't provide a Letter of Medical Necessity when the plan requests one.
IRS Publication 502 excludes cosmetic procedures — anything done to improve appearance rather than to treat disease or a deformity from injury or illness. Botox used to smooth wrinkles is cosmetic and isn't reimbursable from an FSA.
The medical uses are different. When a physician prescribes Botox for a diagnosed condition — chronic migraine, severe underarm sweating (hyperhidrosis), muscle spasticity, or cervical dystonia — it's treatment, not cosmetics, and can be a qualified expense.
Since the same injection can be either, FSA administrators usually want a Letter of Medical Necessity naming the diagnosis and confirming Botox as the treatment. Without it, a Botox claim is typically denied or reversed on audit.
