Below is a partial list of some of the Managed care groups and their primary carriers that Dr. Nienaber is a preferred provider for. There are too many individual plans and carriers to list them all. If yours does not appear, it does not mean that you do not have chiropractic benefits so please contact our office for other plans. Also, individual plans differ in coverage therefore your specific benefits can not be guaranteed until verified.
