How Do I File a Workers' Compensation Claim in Missouri?

Getting hurt at work is disorienting. Between the pain, the medical appointments, and the pressure to stay productive, the last thing most people want to deal with is paperwork and legal procedures. But in Missouri, how you handle the first days after a workplace injury can have a permanent effect on whether you receive workers' compensation benefits — and how much.

Missouri workers' compensation is a no-fault system. You do not need to prove your employer was negligent. If you were injured while performing work duties, you are generally entitled to medical care, wage replacement, and disability compensation. The catch is that the system has strict deadlines and specific procedures that must be followed. Miss them, and your claim may be denied — regardless of how serious your injury is.

This guide explains exactly how to file a workers' comp claim in Missouri, step by step. If you have already been injured and need guidance tailored to your specific situation, contact Bur Oak Legal for a free consultation. No fee unless we win.

Step-by-Step: How to File a Workers' Comp Claim in Missouri

1. 1
   Report the injury to your employer — within 30 days

   This is the most time-sensitive step. Under RSMo § 287.420, you must notify your employer of a workplace injury within 30 days of the accident. If you fail to report in time, your employer can use that as a basis to deny the entire claim. Report the injury to your supervisor or HR department in writing — keep a copy. Be specific: describe where the injury happened, when, how, and what part of your body was affected. Even if you think the injury is minor, report it. Many injuries that seem minor at first — back strains, shoulder pain — turn out to be much more serious. Learn more about what to include on a workers' comp injury report.

2. 2
   Your employer files a First Report of Injury with their insurer

   Once you report the injury, your employer is required to notify their workers' compensation insurance carrier. The insurer opens a claim file and assigns an adjuster. That adjuster works for the insurance company — not for you. Their job is to investigate the claim and manage the company's exposure. You may be asked to give a recorded statement. Do not do this without first consulting with an attorney. Statements given without legal guidance can be used to minimize or deny your claim. See our post on workers' comp recorded statements for what to expect.

3. 3
   Seek medical treatment — with the authorized treating physician

   In Missouri, the employer and their insurer have the right to choose your authorized treating physician (ATP). You must treat with this doctor for the insurer to pay your medical bills. Seeing an unauthorized provider on your own does not obligate the insurance company to pay for that treatment. The ATP will manage your care, order imaging and referrals, and eventually make the determination that you have reached maximum medical improvement (MMI) — the point at which your condition is unlikely to improve further. That determination matters enormously for your claim, so take your medical treatment seriously and document everything.

4. 4
   The insurer accepts or denies the claim

   After investigating, the insurer will either accept the claim and begin paying benefits, or deny it. Common reasons for denial include: the insurer disputes that the injury happened at work, claims the injury was pre-existing, argues that the injury is not serious enough to require compensation, or asserts that you missed the reporting deadline. If your claim is denied, you have the right to contest it — but you must act promptly. Read more about what to do when your workers' comp claim is denied.

5. 5
   If disputed, file a Claim for Compensation with the Missouri DWC

   If the insurer denies or disputes your claim, you can file a formal Claim for Compensation with the Missouri Division of Workers' Compensation (DWC). The DWC is the state agency that resolves disputed workers' comp claims through its administrative law judges. Filing a claim triggers the formal dispute process — both sides present evidence, medical opinions are evaluated, and a judge issues a decision. Before I entered private practice, I worked inside the Missouri Division of Workers' Compensation. I know how this process works because I was part of it.

What Happens After You File with the DWC

When a Claim for Compensation is filed, the DWC opens a case file and the dispute enters the administrative process. A pre-hearing conference is typically scheduled first, where the parties discuss the issues in dispute and attempt to narrow the case. If the dispute is not resolved, the case proceeds to a full hearing before an administrative law judge.

At the hearing, both sides present evidence: medical records, expert testimony, witness statements, and documentation of lost wages. The judge evaluates the evidence and issues a written decision — called an award — that determines what benefits, if any, you are entitled to receive. The award can cover medical care, temporary total disability (TTD) benefits paid while you could not work, and permanent partial or total disability if your injury left lasting impairment.

If you disagree with the administrative law judge's award, you can appeal to the Labor and Industrial Relations Commission. Decisions from the Commission can be further appealed to the Missouri Court of Appeals. The appeals process takes time, but it exists precisely because injured workers deserve fair review of their claims.

Understanding the Benefits Available in a Missouri Workers' Comp Claim

Missouri workers' compensation provides several categories of benefits to injured workers:

• Medical benefits — All reasonable and necessary medical treatment related to the work injury, including doctor visits, surgery, physical therapy, and prescription medications. The employer/insurer selects the treating physician.
• Temporary total disability (TTD) — Wage replacement equal to two-thirds of your average weekly wage while you are unable to work, subject to a statewide maximum. TTD continues until you return to work or reach MMI.
• Temporary partial disability (TPD) — Wage replacement if you return to work in a reduced capacity (lighter duty, fewer hours) and are earning less than before your injury.
• Permanent partial disability (PPD) — Compensation for lasting impairment after you reach MMI. A rating physician assigns a percentage of disability to the affected body part, which is converted to a number of weeks of compensation.
• Permanent total disability (PTD) — Weekly benefits for life if you are so severely injured that you cannot return to any gainful employment.
• Vocational rehabilitation — Job training or retraining if your injury prevents you from returning to your previous occupation.
• Death benefits — Paid to surviving dependents if a worker dies as a result of a work-related injury.

Do You Need a Workers' Comp Attorney?

You are not legally required to have an attorney to file a workers' comp claim in Missouri. But the workers' compensation system is not as simple as it sounds, and insurers are experienced at minimizing claims. Workers who handle their own cases often end up with settlements that do not fully reflect the value of their injuries — or have claims denied on procedural grounds that an attorney would have avoided.

An attorney can help you: make sure the 30-day report and 2-year filing deadlines are not missed, challenge an unfair denial, dispute a premature MMI determination, negotiate a full and fair settlement at the end of your claim, and represent you at DWC hearings if the case goes that far.
