For insurance to pay for TMJ, you have to have it by a specific type of physician, and not a dermatologist or plastic surgeon. I do not believe Medicare will pay for TMJ Botox services regardless of who does them. But be aware that physicians who bill insurances for these services bill at astronomical rates simply so they can get the same amount those of us who bill as cosmetic physicians do. Thus, I've seen some patients go to doctors for these services under insurance and pay way more than they would have if they saw a cosmetic physician... because of their copays, coinsurance, and deductible amounts."This answer has been solicited without seeing this patient and cannot be held as true medical advice, but only opinion.
