While Botox cannot treat Bell's palsy, it can create symmetry by weakening muscles on the contralateral side, giving a more symmetrical look.While this would certainly seem like a medically indicated procedure, insurance companies are tricky in what they authorize.One argument an insurance company could have is that the Botox does not treat the actual Bell's palsy, and, hence, it is not beneficial to treat the medical condition.A counterargument would be that surgery has been done and paid for in the past for corrective procedures on the opposite side from Bell's palsy for the same purpose.In this case, written preauthorization is mandatory if attempting to get insurance to pay for the procedure.One of the challenges this places on the doctor is the insurance company may very well pay for the injections.Reimbursement for injections is minimal, usually only a small fraction of the cost of the Botox medication itself.Should the insurance company fail or make it difficult for the provider to be reimbursed for his or her cost of the actual Botox, the provider could lose a substantial amount of money.There are many neurologists and other specialists that treat headaches with Botox with insurance compensation.Many of these doctors also perform other Botox-type treatments and are quite talented.Perhaps find a neurologist who does this kind of work since they will be much more familiar with insurance authorization for Botox treatments. They are also the ones who, for the most part, treat and manage Bell's palsy, so you probably already have a neurologist who may be able to refer you to someone else.Best of luck,Mats Hagstrom, M.D.
