Botox cost: units, price per unit and the fee per session
Choose the area and, if you have one, the price per unit you were quoted: the units come from the FDA label, the toxin cost from the Medicare file.

The price of a botulinum toxin session rests on units. The FDA label of Botox Cosmetic, onabotulinumtoxinA, sets the dose for each approved area: 20 units for the frown lines between the brows, often called the 11 lines, 24 for crow's feet on both sides, 40 for forehead lines treated together with the frown lines, 64 for the three areas at once. Medicare's payment limit for the drug itself, code J0585, is $6.51 a unit in the October 2026 file, so the toxin for the frown lines costs about $130 at that price and the three areas about $417. Practices usually quote a price per unit that includes the injector's time and their margin, which is why a quote per unit is several times the Medicare limit. No public file publishes what injectors charge, so the calculator compares the price per unit you were quoted with the toxin's own cost, rather than with an average.
Units per area, from the label
The FDA-approved label of onabotulinumtoxinA for cosmetic use, revised October 18, 2024, gives a fixed dose for each indication. It is the only official reference for how many units an area takes; injectors adjust doses to each patient, and areas outside the label are treated off label at doses the label does not set. The table multiplies each labeled dose by the Medicare payment limit for the drug, which is the closest public price of the toxin itself.
| Area on the label | Units | Toxin at the Medicare limit |
|---|---|---|
| Frown lines between the brows | 20 | $130 |
| Crow's feet (both sides) | 24 | $156 |
| Forehead and frown lines together | 40 | $261 |
| Frown lines, crow's feet and forehead | 64 | $417 |
| Neck bands, one band each side | 26 | $169 |
Price per unit and price per area
Practices price neuromodulators in two ways: per unit, or per area. Per unit makes quotes comparable, as long as the brand is the same. A price per area can be turned into a price per unit by dividing it by the units the injector plans to use, which the label gives for each approved area. Typing the price per unit you were quoted into the calculator shows the amount for the area and how far it sits above the toxin's own Medicare price; that gap is what pays for the injector's time, the visit and the practice's margin.

Other brands are not interchangeable
The CMS file gives a limit for each toxin, but their units are not equivalent. Abobotulinumtoxin A is priced per 5 units at $8.94, incobotulinumtoxin A at $5.26 a unit and daxibotulinumtoxin A at $3.25 a unit, and each label sets its own doses. A price per unit therefore compares only within one brand.
The cost over a year
The effect of a session wears off, so the cost that matters is yearly. The label of Botox Cosmetic states that dosing more often than every three months has not been clinically evaluated, so three or four sessions a year is the usual range of the arithmetic. For the frown lines, the toxin alone comes to $391 a year over three sessions and $521 over four at the Medicare limit; multiply your own price per session the same way to get the yearly cost of your quote. Health plans and Medicare do not pay for cosmetic injections; the same molecule, sold as Botox for medical uses such as chronic migraine, can be covered for those uses. The brow lift page sets the toxin beside a one-time operation, without comparing the treatments themselves.
