If chronic migraines are ruling your life, Botox can be a genuine treatment, and Medicare does cover it, but only for the right kind of migraine and only when other treatments have not worked. The key is understanding the difference between the Botox that treats migraines and the Botox that smooths wrinkles. This guide explains what Medicare covers, what you will pay, and how to get approved. Coverage and costs change, so verify current details before relying on them.
The Short Answer
Yes, for chronic migraine. Original Medicare Part B covers Botox (onabotulinumtoxinA) as a treatment for chronic migraine when it is medically necessary and given by a provider. It is not covered for cosmetic use, and generally not for occasional or episodic migraine.
Why It Falls Under Part B
Because Botox for migraines is injected by a provider in a clinic rather than something you pick up at a pharmacy, it is covered as a Part B drug and service, not under Part D. Part A would apply only if it were given during a covered inpatient stay, which is unusual.
What Counts as Chronic Migraine
Medicare covers Botox for chronic migraine, commonly described as headaches on 15 or more days a month, with migraine features on many of those days, typically after other preventive treatments have failed. That āfailed other treatments firstā requirement, sometimes called step therapy, is central. Botox for occasional or episodic migraines, and cosmetic Botox for wrinkles, are not covered.
What You Will Pay
After the Part B deductible, about $283 in 2026, you pay 20% of the Medicare-approved amount for the drug and its administration. Your exact dose and number of injection sites vary, so there is no single session price. A Medigap policy can cover that 20% coinsurance.
The Medicare Advantage Angle
Medicare Advantage plans cover Botox for chronic migraine too, but they very frequently require prior authorization and step therapy, meaning you must document that other preventive medications did not work before the plan approves it. Copay structures vary, so check your plan.
How to Get Approved
Work with a neurologist or headache specialist who documents your chronic migraine diagnosis, a headache diary showing your headache days, and the preventive medications you have already tried without success. Obtain prior authorization where required, and use a Medicare-enrolled provider. Treatment is typically given about every 12 weeks when the criteria are met. If a request is denied, you can appeal, and adding your headache diary and treatment history often makes the difference.
How to Check Your Coverage
Call the number on your Medicare or plan card and ask specifically about coverage for Botox for chronic migraine, any prior-authorization or step-therapy requirements, and how often treatment is allowed. If you have a Medicare Advantage plan, ask for its written medical policy so you know the exact criteria before you start.
What to Expect From Treatment
It helps to have realistic expectations. Botox for chronic migraine is a preventive treatment, given as a series of small injections around the head and neck about every 12 weeks, not a treatment you take when a migraine strikes. It often takes more than one round to know whether it is working, so most protocols try at least two treatment cycles before deciding. It reduces how often and how severely migraines occur rather than curing them, and it is usually one part of a broader plan that may include other medications and lifestyle measures. Keeping a headache diary throughout is useful both for your care and for continued coverage, since plans often want to see that the treatment is helping.
When Botox Is Covered and When It Is Not
The reason for the Botox matters a great deal. Medicare covers it when it is medically necessary, not cosmetic.
For chronic migraine, coverage generally requires a documented diagnosis and a history of frequent headache days. Botox for wrinkles or cosmetic reasons is not covered. Your doctor must show it is treating a medical condition. Keep records of your migraine frequency and prior treatments.
Even when Botox is covered, you usually share the cost. The exact amount depends on your plan.
Under Part B, you typically pay a share after your deductible. A Medicare Advantage plan may handle it differently, with its own rules and prior authorization. Ask your plan what your out-of-pocket cost will be. Confirming this before treatment avoids surprises.

Is cosmetic Botox ever covered?
No. Botox for wrinkles or appearance is never covered.
Is it under Part B or Part D?

How long before Botox starts helping my migraines?
It often takes more than one treatment cycle, so most people try at least two rounds about 12 weeks apart before judging whether it works.
Is Botox a cure for migraines?
No. It is a preventive treatment that can reduce how often and how severely migraines occur, usually alongside other measures.
