Your health care provider is required to use the Montana Utilization and Treatment Guidelines for your care. If there's a particular treatment or service that's denied by your workers' compensation insurer, you may request additional review by the Medical Director of Montana L&I. If the Medical Director doesn't approve the request, you can request a mediation. If that happens, it's a good idea to have a Montana workers' compensation lawyer along with you. Your lawyer will help advocate for your needs so that you have your medical expenses covered.
