Revise workers' compensation laws.

This bill revises Montana's workers' compensation laws to clarify when insurers can require payment without accepting liability and how benefits are handled during disputes. It allows the workers' compensation department to order temporary benefit payments of up to 49 days when an insurer terminates benefits and the worker contests the decision, provided the worker shows they are likely to win the dispute. The bill also permits insurers to pay for medical treatment without admitting fault for the injury and outlines specific situations where workers may lose benefits for refusing to cooperate with medical care or treatment plans. These changes directly affect injured workers, insurance companies, and the state workers' compensation department by modifying how claims are processed and disputes are resolved.
