If you were hurt at work in Missouri, you have the right to file a workers' compensation claim — but the process has specific steps and strict deadlines. Missing even one of them can give the insurance company grounds to deny your claim. This page walks through exactly how to file a workers comp claim in Missouri, from the moment of injury through receiving the benefits you're owed. When you're ready to get started, contact Bur Oak Legal for a free consultation with attorney Chris Miller — former attorney at the Missouri Division of Workers' Compensation.
Why the DWC background matters: Before representing injured workers in court, Chris Miller worked inside the Missouri Division of Workers' Compensation — the state administrative body where disputed claims are heard and decided. He knows how the process works because he ran it. That insider knowledge is something most workers' comp attorneys simply don't have.
A workers' compensation claim is a formal request for benefits after a workplace injury or occupational disease. Missouri workers' compensation is a no-fault system — you don't have to prove your employer was negligent, only that the injury occurred at work and arose out of your employment. The system is governed by Chapter 287 of the Missouri Revised Statutes and administered by the Missouri Division of Workers' Compensation.
When your workers' comp claim is accepted, it can cover all reasonable and necessary medical treatment, replace a portion of your lost wages, and compensate you for permanent disability to injured body parts. If your injury prevents you from returning to any employment, total disability benefits may also be available.
All reasonable and necessary medical care — emergency services, surgery, physical therapy, prescriptions — paid by the employer's insurer, not you.
Temporary total disability (TTD) pays two-thirds of your average weekly wages if you can't work during recovery.
Once you reach maximum medical improvement, a physician rates any permanent impairment to your injured body parts. That rating determines your compensation.
Missouri workers' compensation has a specific sequence of steps, and each one matters. Here is how the process works from beginning to end.
The most important thing injured workers can do after a workplace injury is report it to the employer immediately. Missouri law requires written notice within 30 days of the accident — or within 30 days of the date you first discovered the on the job injury and its connection to your job. This 30-day notification rule is set by RSMo § 287.420, and it is strictly enforced.
Report to a supervisor or HR representative in writing and keep a copy. Your report should include the injury date, the circumstances of the accident, and a description of the body parts involved. If you delay beyond 30 days, the insurance company can argue that the late notice should bar your claim entirely — even if the injury is serious.
There is an exception for occupational disease claims, where the condition develops gradually over time due to work exposure. For those cases, the 30-day period runs from the date you knew — or reasonably should have known — that your condition was caused by your employment.
Get medical care as soon as possible after the injury. Missouri law gives your employer the right to direct you to an authorized treating physician — the employer's choice of doctor — for initial and ongoing medical care. You are generally required to treat with that authorized provider. If you see your own doctor without authorization, the insurer may refuse to pay those medical bills.
Make sure every appointment accurately documents your symptoms, limitations, and pain levels. Do not downplay how you feel. Future medical treatment decisions — including surgeries, specialist referrals, and physical therapy — are driven by what your treating physician documents. Keep records of all appointments, prescriptions, and medical bills. You will need that documentation throughout the claims process.
Once you report the work related injury, Missouri law requires your employer to file a First Report of Injury (Form WC-10) with their workers' compensation insurance carrier. This document formally notifies the insurer that an accident occurred and that a claim may be filed. It identifies the injured employee, the employer, the injury date, and the circumstances of the accident.
This step is your employer's responsibility, not yours. However, you have the right to receive a copy. If your employer refuses to file or claims the injury didn't happen at work, contact the Missouri Division of Workers' Compensation directly. The Division can assist injured employees who are encountering resistance from employers who refuse to cooperate.
After the First Report of Injury is submitted, the insurance company investigates the workers' comp claim. A claims adjuster reviews your injury report, examines your medical documentation, speaks with witnesses, and assesses whether to accept or deny the claim. Insurance companies look for reasons to deny or minimize your claim — common grounds include disputing the accident happened at work, claiming the injury was pre-existing, alleging you were intoxicated, or arguing you were an independent contractor.
If your claim is accepted, you will receive medical care through insurer-approved providers and may receive temporary total disability (TTD) wage replacement payments — equal to two-thirds of your average weekly wages — if you are unable to work. Once your condition reaches maximum medical improvement (MMI), a physician evaluates any permanent disability to your injured body parts, and that rating determines your permanent partial disability (PPD) payment.
If your workers' comp claim is denied — or if there is any dispute about benefits — you can file a Claim for Compensation (Form WC-21) with the Missouri Division of Workers' Compensation. This compensation form formally opens your case in the state workers' comp system and starts the official dispute resolution process. Filing it gives you access to an administrative law judge to hear your case.
When a Claim for Compensation is filed, the Division assigns a Jurisdiction Control Number (JCN) — the state's official tracking identifier — to your case, and mails notice to all parties. The case then enters the Division's pre-hearing conference process.
You have two years from the injury date — or from the date of the last payment of compensation or the last date medical treatment was provided — to file a Claim for Compensation. Missing this statute of limitations typically results in a dismissed claim. The two-year clock moves whether you're watching it or not.
Most workers' comp disputes in Missouri are resolved through negotiated settlement rather than a formal hearing. Cases can settle through a Stipulation for Compromise Settlement — a lump sum that closes the case completely — or a Stipulation Award that may leave future medical treatment open. If the parties cannot agree, the case proceeds to a hearing before an administrative law judge at the Division.
The judge reviews the evidence and issues an award determining what workers' compensation benefits the injured employee is entitled to receive. Awards can be appealed to the Labor and Industrial Relations Commission and, from there, to the Missouri Court of Appeals. The formal hearing process is adversarial — insurance companies are represented by defense lawyers. Workers who proceed without representation are at a significant disadvantage in many cases.
Missouri workers' compensation has two time limits that can permanently destroy your claim if missed. Both are strictly enforced, and courts rarely make exceptions.
Written notice to your employer within 30 days of the injury (or the date you discovered an occupational disease). Set by RSMo § 287.420. Missing this deadline gives the insurer a basis for complete denial. There are narrow exceptions, but you cannot count on them.
File a Claim for Compensation with the Missouri Division within two years of the injury date, or within two years of the last date compensation or medical treatment was provided. If your employer or insurer paid any medical bills after the injury, the clock may have restarted from that payment date — but do not rely on that assumption without confirming it with an attorney.
If you are unsure where you stand on either deadline, contact a workers' comp lawyer before assuming you have more time. Many workers lose valid claims simply because they waited too long to act.
Understanding what benefits your workers' comp claim can provide is important before you begin the process.
Understanding all available workers' compensation benefits before settling is essential — you can't reopen a closed case after the fact.
Some employers claim a workplace injury didn't happen, discourage workers from filing, or refuse to submit the First Report of Injury. Missouri law prohibits employer retaliation against injured employees under RSMo § 287.780. If your employer fires you, demotes you, or penalizes you for filing a workers' comp claim, you may have a separate legal claim for wrongful termination.
If your employer refuses to file a First Report of Injury, contact the Missouri Division of Workers' Compensation directly. You can also file a Claim for Compensation on your own — you do not need your employer's cooperation to open a case with the Division.
If your employer does not carry workers' compensation insurance — required for most Missouri employers with five or more employees — you may have a claim through the Missouri Uninsured Employers' Fund. An uninsured employer can also be held liable in a personal injury lawsuit, which allows for damages not available in normal workers' comp claims, including pain and suffering. Workers injured by uninsured employers are among the most vulnerable victims in the system, and getting legal help early is especially important in those cases.
Not every workers' comp claim involves a single traumatic accident. Occupational disease claims cover conditions that develop gradually as a result of repeated work exposure — including carpal tunnel syndrome, repetitive stress injuries, hearing loss, respiratory disease from chemical inhalation, and conditions caused by toxic exposure on the job.
For occupational disease claims, the injury date for statute of limitations purposes is typically the date you knew — or should have known — that your condition was work-related. Medical documentation is especially important in these cases. Many workers in manufacturing, construction, and labor-intensive jobs across central Missouri develop these conditions over years without realizing they have a valid workers' comp claim.
Missouri employers with five or more employees are required to carry workers' compensation insurance. Employers in the construction industry must carry coverage with even one employee on the payroll. The insurer is required to begin paying temporary total disability benefits promptly after accepting a claim under Missouri workers' compensation law.
When filing a workers' compensation claim in Missouri, injured employees must complete and submit Form WC-21 (Claim for Compensation) to the Division of Workers' Compensation, including all relevant medical documentation and witness statements. Workers must also complete and submit a First Report of Injury (Form WC-10) through their employer at the time of the accident. When a Claim for Compensation is filed, the Missouri Division assigns a Jurisdiction Control Number (JCN) to track the case through the state system. Most cases enter a pre-hearing conference process and resolve at this stage through negotiated settlement without proceeding to a formal evidentiary hearing.
Insurance companies have experienced adjusters, nurses, and defense lawyers whose sole job is to investigate, challenge, and minimize workers' comp claims. A workers compensation lawyer levels the playing field. Having legal representation significantly increases the likelihood of receiving the full benefits owed in a workers' compensation claim — because insurance companies routinely look for reasons to reduce or deny payments, and an attorney knows how to counter those tactics with properly documented evidence.
Before representing injured workers across central Missouri in private practice, Chris Miller worked inside the Missouri Division of Workers' Compensation — the state agency that administers disputed workers' comp claims. He knows how adjusters investigate, how defense lawyers build their cases, and how administrative law judges evaluate disputed claims. That experience, inside the system and now on the plaintiff side, is what Bur Oak Legal brings to its clients.
You should contact a workers compensation lawyer as early in the process as possible — ideally before your first recorded statement with the insurance company. Having representation from the start prevents early mistakes from following you through the entire process.
Legal representation is especially crucial during the appeals process for denied workers' compensation claims. Appealing a denial through the Missouri Division, the Labor and Industrial Relations Commission, or the Missouri Court of Appeals is a complex process with strict procedural requirements. Workers who attempt to navigate appeals without expert guidance frequently miss deadlines, fail to preserve key arguments, or accept unfavorable outcomes that could have been reversed with proper representation.
