Montana workers' compensation — your first doctor, their approval after, one year to claim.

Montana lets you pick your first treating physician — a right many bigger states don't give — then requires insurer approval to change. The clocks are moderate but real: thirty days to report, twelve months to file the claim. And when disputes harden, Montana sends them to its own specialized Workers' Compensation Court.

How the Montana system works

Most Montana employers must carry coverage — many through the Montana State Fund — overseen by the Department of Labor & Industry, with mediation required before contested cases reach the specialized Workers' Compensation Court in Helena. Montana also runs practical return-to-work programs (stay-at-work assistance) that can pay employers to bring you back on modified duty.

Every deadline that matters

Your first doctor — their approval after

Choose your opener carefully

Montana workers generally select their initial treating physician — and after the insurer accepts liability, it gains approval rights over changes and can designate a treating physician for ongoing management. Translation: your first choice matters double, because it may be your freest one. Pick a doctor who documents thoroughly and takes work-injury causation seriously; their early records anchor everything that follows.

Montana FAQ

After acceptance, the insurer has real say over the treating-physician designation — but "real say" isn't unlimited, and disputes go to mediation. Keep treating, object in writing if the proposed change would genuinely harm your care, and get advice before agreeing to anything that moves you away from a doctor who's documenting well.
Montana programs that fund modified duty — helping employers pay for adjusted work while you recover. Used well, they keep your paycheck and your job connection alive; used badly, they pressure premature returns. The test is always your written restrictions: work within them, and escalate to your doctor anything that exceeds them.
Montana workers' compensation has generally covered injured workers regardless of status. Report in writing, file inside twelve months, and use the Department's free claim assistance.
