Revise workers' compensation definition of treating physician to include physical therapists

This bill amends Montana's workers' compensation law to officially recognize physical therapists as treating physicians within the state's workers' compensation system. The change directly affects injured workers, employers, and insurance providers by expanding the definition of who can provide medical care under the program. By updating the legal definition of "treating physician" in the relevant statute, the bill allows physical therapists to perform the same duties and receive the same recognition as physicians when treating work-related injuries. This change aims to streamline care options for injured workers while maintaining the existing framework for medical treatment and benefits.
