SB 345 Montana Senate · 2025 Regular Session

Revise workers' compensation laws relating to evidentiary standards

SB 345 would change how medical evidence is evaluated in Montana workers' compensation cases. It removes automatic preference for treating physicians' opinions, requiring courts to weigh medical testimony based on the provider's qualifications, experience with the specific worker, and credibility. The bill also limits discovery about independent medical examiners (IMEs) to their training, exam volume, and payments from insurers, aiming to reduce bias concerns. These changes directly affect workers seeking compensation, insurers requesting medical evaluations, and medical providers involved in these cases. The bill was introduced in 2025 but died in committee before becoming law.
