Why Would Botox Therapy Treatment Cost $4090.00 for a Single Treatment That Took 15 Minutes?

I am a dermatologist and my husband is a headache specialist so I think that I can answer this fairly reasonably. Dermatologists use lower doses of Botox when using it for cosmetic purposes. The average that I use for a woman's face is 40-50 units. Botox prices range from $10-$15 a unit ,varying in areas of the USA. When headaches are treated most neurologist use  about 150 units. Insurance reimburses the cost of most of the Botox(some pay less per unit than it costs the doctor to buy) and usually an injection fee that is a couple to a few hundred dollars at most(insurance here pays $1,000). So, we are talking about something in the one thousands range not $4,090. If you were charged cosmetic fees for 150 units at most should be 2,250. If insurance paid some and you could be balance billed, $800 is not out of range but the original charge makes no sense. Call and ask about it. 

   Some doctors who inject Botox for migraines lose money on the injections, and there are very few who inject with payment from insurance.   I would suspect that the insurance barely covered the cost of the Botox no matter what the initial bill appeared to be.

Without knowing what your itemized charges were, it's very difficult to answer your questions. While the treatment doesn't take very long, cost is not dependent upon time, but number of units. In your case, it sounds like there may be an issue with medical versus cosmetic use and what they're willing to pay for.
