Quick Answer
Medicare covers Botox injections when they are medically necessary and FDA-approved for a specific condition. Covered conditions include chronic migraines (15+ headache days/month), overactive bladder, cervical dystonia, upper limb spasms, eyelid muscle spasms (blepharospasm), and excessive underarm sweating (hyperhidrosis). **Cosmetic Botox for wrinkles is not covered** unless the condition results from an accident or injury.
Coverage Comparison by Plan Type
| Plan Type | Coverage | Notes |
|---|---|---|
| Original Medicare (Part B) | Covered - medically necessary Botox | Covers 80% of outpatient Botox for approved conditions after Part B deductible |
| Original Medicare (Part A) | Partial - inpatient only | Covers Botox administered during an inpatient hospital stay |
| Medicare Advantage | Covered - varies by plan | Must cover same conditions as Original Medicare; prior auth often required |
| Medigap (Plan G) | Covered - cost-sharing | Covers the 20% Part B coinsurance for all Medicare-approved Botox sessions |
Understanding Your Coverage Options
Original Medicare (Part B)
Covered when medically necessary and FDA-approvedMedicare Part B covers Botox injections administered in a doctor's office or outpatient clinic when the treatment is medically necessary and FDA-approved. Part B pays 80% of the Medicare-approved amount; you pay the remaining 20% after meeting your annual Part B deductible ($240 in 2024).
The typical Botox dosage for chronic migraines is 155 units, costing approximately $300–$600 per treatment session. With Part B covering 80%, your out-of-pocket cost per session would be approximately $60–$120 without a Medigap plan.
Before receiving Botox, you must typically try other treatments first and show no improvement. Your doctor must document that Botox is medically necessary for your specific condition. Contact your plan before treatment to confirm coverage and whether prior authorization is required.

Contact Your Plan before Scheduling
Always contact your Medicare plan before receiving Botox injections to confirm coverage and prior authorization requirements. Your doctor may need to submit documentation of medical necessity.
Medicare Advantage
Covered - prior authorization often requiredMedicare Advantage plans must cover the same Botox treatments as Original Medicare. However, cost-sharing, prior authorization requirements, and network restrictions vary by plan.
Some Advantage plans may offer additional coverage for Botox beyond the Original Medicare minimum, but cosmetic Botox remains excluded across all plan types.
Prior authorization is commonly required for Botox under Advantage plans. Your plan may also require you to see a specialist (neurologist, urologist, or dermatologist) rather than a primary care physician for the injection.
Costs vary by plan. Some plans may have fixed copays for specialist visits where Botox is administered.
Check Prior Authorization Requirements
Check whether your Advantage plan requires a referral or prior authorization for Botox injections before scheduling your appointment.
Medigap (Medicare Supplement)
Covers 20% coinsurance for all Medicare-approved BotoxA Medigap Plan G covers the 20% Part B coinsurance for Medicare-approved Botox treatments. Since Botox for conditions like chronic migraines requires repeated treatments (typically every 12 weeks), Medigap can provide significant savings over time.
With Plan G, your only out-of-pocket cost for Medicare-approved Botox is the annual Part B deductible ($240 in 2024), after which all covered Botox treatments are paid at 100%.
If you receive Botox reimbursement from Medicare (i.e., your doctor does not bill Medicare directly), you may need to file a Medicare reimbursement claim. This is rare but can happen if your doctor does not accept Medicare assignment.
With Plan G: $0 per Botox session after the annual Part B deductible. Without Medigap: 20% of each session's cost.

✦ When Medicare Won't Cover Botox
Cosmetic Purposes
Medicare does not cover Botox for cosmetic purposes - reducing wrinkles, fine lines, or other aesthetic treatments. The only exception is if cosmetic Botox is medically necessary due to an accident or injury (e.g., facial nerve damage).
Fewer than 15 Migraine Days per Month
For migraine coverage, you must experience 15 or more headache days per month. Botox is not covered for episodic migraines (fewer than 15 days/month). Your neurologist must document the frequency of your migraines.
No Prior Treatment Attempts
Medicare requires that you try other treatments first and show no improvement before approving Botox. Your doctor must document these prior treatment attempts in your medical record.
Non-FDA-Approved Applications
Botox for conditions not yet FDA-approved (such as depression, premature ejaculation, or certain pain conditions) is not covered by Medicare, even if your doctor recommends it.
