Montana Workers’ Compensation: Claims, Benefits, and Denials

Montana workers’ compensation is a no-fault insurance system that pays medical bills and a portion of your wages if you’re hurt on the job or develop a work-related illness, without requiring you to prove your employer did anything wrong. In return, your employer is generally protected from a personal-injury lawsuit. To get benefits you have to move quickly: tell your employer within 30 days and file a written claim within 12 months.

Who Is Covered

If you work for a Montana employer under almost any hiring arrangement, you’re covered. Full-time, part-time, and seasonal work all count, and the system reaches state and local government employees, school district workers, and employees of public corporations.¹ The Workers’ Compensation Act applies to every employer with at least one employee.

A few groups fall outside the mandatory system. Household and domestic workers are excluded. So are casual employees whose work isn’t part of the employer’s regular business. Independent contractors who hold a valid exemption certificate from the Department of Labor and Industry have formally waived their workers’ comp rights, and an injury on the job under that certificate produces no benefits from the hiring party’s policy.²³

The system covers two kinds of harm. A workplace injury is a single incident: a fall, a machine accident, a strain while lifting. An occupational disease develops over more than one shift from ongoing job conditions, such as hearing loss from years of factory noise or a respiratory condition from prolonged dust exposure.⁴ One boundary matters here: mental or emotional conditions caused by nonphysical stress, such as harassment or job pressure, are not occupational diseases under Montana law.

Reporting the Injury and Filing a Claim

You have 30 days from the accident to notify your employer or a supervisor. Miss that window and your claim can be declared non-compensable, which means no benefits at all, no matter how serious the injury. There is one safety valve: if your employer or an on-site manager already had actual knowledge of the accident and your injury, that counts as notice even without a formal report from you.⁵

After giving notice, you have 12 months from the accident to file a written claim. The form is called the First Report of Injury or Occupational Disease (FROI). It asks for the date, time, and location of the incident, a description of what happened, and details about your injury. You and your employer can complete it together or submit separate forms, and it goes to the employer’s insurer or directly to the Department of Labor and Industry.⁶⁷

For occupational diseases, the 12-month clock runs from the date you knew or should have known that your condition came from your job, not from any specific incident.⁶ Many of these conditions take years to develop, and the connection to work often isn’t clear until a doctor identifies it.

See a doctor as soon as possible after the injury. The insurer will look for objective medical findings, and a gap between the accident date and your first visit creates questions that slow the claim.

What the Insurer Must Do

Once the insurer receives your signed claim, it has 30 days to accept or deny it. A denial has to be in writing and reported to both you and the Department of Labor and Industry.⁸

Even after an acceptance, wage-replacement benefits don’t start on day one. The first 32 hours or 4 days of total disability, whichever is less, are unpaid. Payments begin on the fifth day. If your disability lasts 21 days or longer, the insurer goes back and pays you retroactively for the waiting-period days.⁹

Medical Treatment

An accepted claim covers all reasonable and necessary medical care related to the workplace injury: doctor visits, surgery, hospital stays, prescriptions, and physical therapy. Charges are paid under the state’s medical fee schedule.

You have the right to pick your own healthcare provider for initial treatment. If that provider agrees to serve as your treating physician and meets the statutory requirements, they become your primary doctor for the claim. Once the insurer accepts liability, however, it has authority to designate or approve a different treating physician.¹⁰

Travel to and from medical appointments is reimbursable. The IRS medical mileage rate for 2026 is 20.5 cents per mile, a common benchmark for these reimbursements.¹¹

Wage-Loss Benefits

Temporary Total Disability

If your injury keeps you from working at all while you heal, you receive Temporary Total Disability (TTD) benefits. The weekly payment equals 66⅔% of your wages at the time of the injury. The maximum is capped at the state’s average weekly wage for the fiscal year in which the injury occurred, with updated rates published each year by the Department of Labor and Industry.¹²

TTD continues until you reach maximum medical improvement or your doctor clears you to return to your pre-injury job or a similar one. If your treating physician releases you to a position with equivalent or higher pay with the same employer, TTD stops even if you haven’t fully healed.¹²

Permanent Partial Disability

When you’ve healed as much as you’re going to but still have lasting limitations, Permanent Partial Disability (PPD) benefits compensate you for reduced earning capacity. A doctor assigns a whole-person impairment rating using the AMA Guides to the Evaluation of Permanent Impairment (sixth edition). Montana then adds percentage points based on your age, education, actual wage loss after recovery, and whether the injury forced you out of heavy physical work into lighter duties. The total percentage is multiplied by 400 weeks to set the duration of benefits. The weekly rate is 66⅔% of your pre-injury wages, but the cap for PPD is half the state’s average weekly wage rather than the full average.¹³

In practice, an older worker with less formal education who takes a significant pay cut after a serious injury will receive substantially more in PPD than a younger, college-educated worker with the same impairment rating and no wage loss. The formula tries to capture the real economic damage, not just the medical diagnosis.

Permanent Total Disability

Permanent Total Disability (PTD) applies when a catastrophic injury permanently removes you from the workforce. It provides long-term income replacement at the same 66⅔% wage rate. Insurers scrutinize these claims heavily given the amounts involved, and legal representation is practically essential if a PTD claim is in play.

Death and Survivor Benefits

If a workplace injury or occupational disease causes death, weekly compensation goes to the worker’s dependents. A surviving spouse receives 66⅔% of the deceased worker’s wages, capped at the state’s average weekly wage, for up to 500 weeks. If the surviving spouse remarries before 500 weeks are up, benefits stop and any remaining payments shift to other eligible dependents such as minor children. If the worker leaves no dependents at all, a lump-sum payment of $3,000 goes to the surviving parent or parents.¹⁴

Retaliation and Return to Work

Your employer cannot fire you because you filed a workers’ comp claim. If your employer terminates you and the real reason is retaliation for claiming benefits, you can take the dispute to district court.¹⁵

You also get a hiring preference when you’re cleared to come back. If you’re medically released to return to work within two years of your injury, the employer where you were working at the time of injury must give you priority over other applicants for any comparable open position that fits your physical condition and skills. The preference doesn’t extend to other companies. Disputes about the return-to-work preference go directly to the Workers’ Compensation Court.¹⁵

Separately, if your injury results in a lasting disability, the Americans with Disabilities Act may require your employer to provide reasonable accommodations such as modified duties, adjusted schedules, ergonomic equipment, or reassignment, unless doing so would impose an undue hardship on the business.¹⁶

The workers’ comp system is otherwise an exclusive remedy. Your employer, its insurer, and your fellow employees are generally shielded from personal-injury lawsuits for a covered workplace injury. The narrow exception is intentional harm: if your employer or a coworker deliberately injured you with specific intent to cause harm, you can sue for damages outside the system. Ordinary negligence, and even recklessness, doesn’t meet that bar.¹⁷

If Your Claim Is Denied

You can’t go straight to court over a denial or a benefit dispute. Montana requires mandatory mediation first. Either you or the insurer can petition the Department of Labor and Industry for mediation, and a neutral mediator will work with both sides to try to resolve the disagreement.¹⁸

The mediator issues a report with a recommended resolution. Each party has 25 days after the report is mailed to accept or reject the recommendation. If either side rejects it, that party can petition the Montana Workers’ Compensation Court for a binding decision. Filing in the Workers’ Compensation Court requires completing mediation first.¹⁹²⁰

The Workers’ Compensation Court is a specialized tribunal that hears only workers’ comp cases. Its judges have expertise in this area of law. Most cases that survive mediation settle before trial, but if yours doesn’t, the court will take testimony, review evidence, and issue a decision.

Taxes and Social Security

Workers’ compensation benefits are not taxable income under federal law. The Internal Revenue Code excludes amounts received under workers’ compensation acts from gross income, so you won’t owe federal income tax on TTD, PPD, PTD, or death benefits.²¹

Social Security Disability Insurance is more complicated. If you collect both workers’ comp and SSDI, the Social Security Administration caps the combined total at 80% of your average earnings before the disability. Any excess is deducted from your SSDI check, not your workers’ comp payment. The offset continues until you reach full retirement age or your workers’ comp benefits end, whichever comes first. Lump-sum settlements can also trigger an offset, so report any settlement to the SSA immediately.²²

When a Lawyer Is Worth It

Montana allows both hourly and contingency fee arrangements with workers’ comp attorneys. For hourly billing, the Workers’ Compensation Court judge determines a reasonable fee based on the attorney’s customary rate, subject to a maximum set by the Department. Under a contingency arrangement, any fees the court orders the insurer to pay are deducted from what you owe under the contingency agreement, so you don’t pay twice for the same work.²³

For straightforward accepted claims involving medical treatment, TTD payments, and a return to work, most people navigate the system on their own. Legal help tends to pay for itself when the insurer denies liability, cuts off benefits, or disputes a PPD rating, and when a PTD claim is in play.
