Is Botox for excessive sweating covered by insurance?
Often yes, but only after the paperwork. Most plans cover injections for severe underarm sweating once prescription strength antiperspirants have failed, and nearly all of them want approval in hand first. Code 64650 is the injection visit for both underarms. The drug itself is billed on a second line, so one treatment produces two charges on the statement.
With approval
Covered after other treatments fail
Both underarms
This code already covers both sides, so it is billed once, not twice. Adding a bilateral marker or a second unit is a fast rejection.
Two charges
The visit is 64650 and the drug is J0585, priced per unit. Patients who were quoted one number are the ones who call about the second bill.
Every 3 months
The effect wears off, so repeat treatment usually lands around the three month mark. Most plans hold a minimum interval and deny anything earlier.
Approval plus math
Prior approval says the plan will pay, not what the patient owes. One check before the appointment shows the deductible left and the coinsurance the payer reports.

When 64650 is the right code
- Severe underarm sweating that soaks through clothing daily
- Prescription strength antiperspirant was tried and failed
- Injections given across both underarms in one session
- Prior approval obtained before the appointment
- Sweating documented as interfering with work or daily life
Documentation payers expect
Payers expect a hyperhidrosis diagnosis, the failed conservative treatments with dates, and a severity score showing daily life is affected. Medicare contractors commonly look for roughly six months of symptoms and a documented conservative trial, so keep the approval number and the exact drug units in the chart.
Why hyperhidrosis injections get denied
What happens after the injections
The sweating comes back, usually in three to six months, so this becomes a standing appointment and a standing approval to renew. Each round brings the drug line J0585 again, and any leftover units in the vial go on their own discarded line. Some plans stop paying the office to buy the drug and route it through a pharmacy instead, which changes who bills the patient. Checking the plan before each round keeps the second bill from arriving as a shock.
64650, quick answers
Will insurance cover injections for sweating?
Most plans do for severe underarm sweating when prescription antiperspirants have failed and approval is granted first. Sweating of the hands, feet, or face is covered less often, reviewed harder, and reported with different codes.
Why did I get two bills for one appointment?
One is the injection visit under 64650 and one is the drug under J0585, priced by the unit. Both run against the same benefits, and both can be checked before the visit.
Does Medicare cover this for hyperhidrosis?
Medicare contractors generally cover it for severe axillary hyperhidrosis when a documented conservative trial has failed and a severity score supports it. Most Medicare Advantage plans require prior approval on top of that.
How often can it be repeated?
Usually about every three months. Plans hold a minimum interval, so booking earlier than the plan allows turns an approved treatment into an unpaid one.
What if the plan denies it?
The office can appeal with the failed treatment history, or quote a self pay price. Either way that conversation is easier before the injections than after.
