We have seen some incredible results with MeRT for Autism, Depression, Post Traumatic Stress, Traumatic Brain Injury, as well as other conditions. It’s possible you may feel frustrated and uncertain about the best course of treatment. We can at least help by providing you with as much information as you would like about this treatment.
MeRT has helped many restore or improve their brain function and reclaim their lives. We want to help you make an educated decision about whether or not MeRT is right for you or your loved one.
Our New Patient Coordinator can answer any questions you have, explain costs and protocols, and can also assist in getting you scheduled for testing and a consultation with the doctor if you would like to explore further.
Insurance Coverage
Currently, rTMS (the treatment used in the MeRT process) is FDA-cleared for treatment of Depression and OCD. If you think you may be able to file for reimbursement from insurance, we can provide you with the documentation you will need to do so. Please note that neither Medicare or Medicaid provide any coverage for MeRT or TMS treatment.
