  • The Medical Director’s review and recommendation is an informal alternative dispute resolution process without administrative or judicial authority and is not binding on the parties. The provisions of this rule apply to medical services provided on or after July 1, 2011.
  • The Medical Director is the specific individual(s) designated by the Department to review the medical records submitted for denied authorizations of treatment for injured workers. The Medical Director may seek consultation from other providers with specialties typically used to manage the type of medical condition being reviewed. If a consultation is sought and received, that provider’s recommendation is also subject to the provisions that govern the Medical Director. A person serving as a Medical Director must be a physician licensed by the State of Montana under Title 37, Chapter 3, MCA.

    The Medical Director may not be called to testify in any proceeding concerning the issues discussed in the Independent Medical Review process. Any recommendations and any information contained in the recommendation is solely from the Medical Director or Specialists consulted and are not admissible as evidence in any action subsequently brought in any court of Law. The Medical Director's recommendation, including information contained in the recommendation, may be considered in mediation conducted under 39‑71‑2401, MCA.

Any new information submitted to the Department must also be submitted to the other party.
  • The Medical Director may, within 5 days of receipt of the Independent Medical Review, request additional time for review or may request additional medical records and then issue a written recommendation to the interested party and the insurer by mail, fax or e-mail not to exceed 14 days from date of receipt of the request. If the Medical Director does not issue a recommendation within 14 days, the request for review is deemed denied and the parties may proceed to mediation.
  • The insurer shall, within 5 days of receipt of the recommendation, notify the interested party, if the previously denied treatment(s) or procedure(s) is authorized based on the Medical Director's recommendation. If the insurer does not authorize treatment after issuance of the Medical Director's recommendation, the interested party may file for mediation with the Department pursuant to 39-71-2401, MCA.
