Quick Answer
Medicare Part B covers Botox injections when they are medically necessary to treat chronic migraines (15 or more headache days per month), upper or lower limb spasticity, cervical dystonia, overactive bladder, or hyperhidrosis. Botox for cosmetic purposes - such as wrinkle reduction - is never covered. When covered, you pay 20% of the Medicare-approved amount after the Part B deductible.

| Medicare Advantage (Part C) | Partial | Must cover medically necessary Botox; check plan for in-network providers |
| Medicare Supplement (Medigap) | Helps with Cost-Sharing | Covers Part B 20% coinsurance when Botox is covered by Original Medicare |
| Medicare Part D | Not Applicable | Botox is administered in a clinical setting under Part B, not Part D |
Understanding Your Coverage Options
Original Medicare (Part a & B)
Medicare Part B covers Botox injections when administered by a physician for a medically necessary condition. Covered conditions include: chronic migraines (defined as 15 or more headache days per month, with at least 8 being migraines), upper and lower limb spasticity, cervical dystonia (abnormal head position and neck pain), overactive bladder, and primary hyperhidrosis (excessive sweating).
Botox must be prescribed and administered by a Medicare-participating provider. After meeting the Part B deductible ($283 in 2026), you pay 20% of the Medicare-approved amount. Botox for cosmetic purposes - including wrinkle reduction or facial aesthetics - is explicitly excluded from Medicare coverage.
Medicare Advantage (Part C)
Medicare Advantage plans are required to cover medically necessary Botox under the same conditions as Original Medicare. Your cost-sharing may differ from Original Medicare depending on your plan. Always verify that the administering provider is in-network to avoid higher out-of-pocket costs.
Medicare Supplement (Medigap)
A Medigap plan such as Plan G covers the Part B 20% coinsurance for Botox injections when they are covered by Original Medicare. If you receive Botox regularly for a chronic condition such as migraines, Medigap can meaningfully reduce your out-of-pocket costs over time.
