If you’ve been hurt on the job in St. Louis, Missouri’s workers’ compensation system is designed to cover your medical care and replace part of your lost wages, generally regardless of who was at fault. But the system is also full of strict deadlines, benefit caps, and rules that can quietly cost you money if you don’t know them.
At NMN Injury Law, our St. Louis workers compensation attorneys have spent decades helping injured workers get the benefits Missouri law entitles them to. This guide walks you through how workers’ compensation actually works in Missouri, what benefits you can expect, and the deadlines you cannot afford to miss.
Quick note on the numbers below: Missouri adjusts its benefit rates every July 1. The dollar figures in this guide apply to injuries occurring July 1, 2025 through June 30, 2026. If you were injured in a different period, the caps that apply to your claim may differ.
Workers’ Compensation Is a “No-Fault” System
Missouri’s workers’ compensation law is found in Chapter 287 of the Revised Statutes of Missouri (RSMo) and is administered by the Missouri Division of Workers’ Compensation, part of the Department of Labor and Industrial Relations.
The core idea is a trade-off. You generally do not have to prove your employer did anything wrong to receive benefits; the statute makes employers liable “irrespective of negligence.” Even if the injury was partly your own fault, you’re typically still covered. In exchange, workers’ compensation is usually your exclusive remedy against your employer, meaning you ordinarily can’t sue your employer in civil court for a workplace injury.
Conduct that can reduce or eliminate benefits
“No-fault” does not mean your own conduct never matters. Missouri law provides for reductions or forfeiture in specific circumstances under RSMo § 287.120:
- Drug and alcohol policy violations. If your injury was sustained in conjunction with the use of alcohol or non-prescribed controlled drugs in violation of your employer’s policy, benefits are reduced by 50%. If that use was the proximate cause of the injury, benefits may be forfeited entirely.
- Refusing a test. Refusing an employer’s request for alcohol or drug testing can result in forfeiture of benefits where the employer had sufficient cause to suspect use or a policy clearly authorizing the test.
- Legal intoxication. Voluntary alcohol use at or above Missouri’s legal intoxication threshold creates a rebuttable presumption that the intoxication was the proximate cause of the injury.
- Safety violations. Failing to obey a reasonable safety rule or to use a provided safety device can reduce benefits.
- Recreational activities. Injuries whose prevailing cause is participation in a voluntary recreational program may be forfeited, with limited exceptions.
These are defenses insurers raise aggressively, and they are frequently applied more broadly than the facts justify. If you’ve been told your benefits are reduced or denied on any of these grounds, have an attorney review the determination.
Which St. Louis Employers Must Carry Coverage
Under Missouri law, most employers with five or more employees are required to carry workers’ compensation insurance. Businesses in the construction industry must carry coverage if they have even one employee.
That means most St. Louis workers in warehouses, hospitals, offices, restaurants, factories, and job sites are covered. But there are three important qualifications.
Exempt occupations
Under RSMo § 287.090, certain types of work fall outside Missouri’s workers’ compensation law regardless of employer size, including:
- Farm labor
- Domestic servants in a private home, including family chauffeurs, and occasional household labor
- Qualified real estate agents and direct sellers
- Commercial motor-carrier owner-operators
- Unpaid volunteers of 501(c)(3) and 501(c)(19) tax-exempt organizations
- Adjudicators, sports officials, and contest workers for interscholastic or amateur youth programs
- Inmates and certain patients or residents performing labor on behalf of the custodial government
Workers covered by federal law instead
Railroad, postal, and maritime workers are covered under federal statutes rather than Missouri’s workers’ compensation system. This matters in a rail-and-river city like St. Louis: railroad employees typically pursue claims under the Federal Employers’ Liability Act (FELA), which is a fault-based system with different rules and deadlines than Missouri workers’ comp.
Don’t assume a small employer means no coverage
If your employer has fewer than five employees, don’t conclude you have no claim. Employers below the threshold can voluntarily elect coverage. Business structure also matters: sole proprietors and partners are not required to carry coverage on themselves but may choose to, while corporate officers, LLC members, and close family-member employees are treated under separate rules in RSMo §§ 287.030 and 287.035.
If your employer was legally required to carry insurance and failed to do so, you may still have a path to recovery, including the ability to pursue a civil lawsuit, and you should speak with an attorney right away.
Are You Actually Covered? Employee vs. Independent Contractor
Workers’ compensation covers employees, not trueof independent contractors. Employers and their insurers sometimes misclassify workers as “contractors” to avoid paying benefits. Whether you’re legally an employee depends on the real nature of the working relationship and how much control the company has over your work, not just the label on your paperwork. If you’ve been told you’re “not covered” because you’re a contractor, that determination is worth having a lawyer review.
What to Do After a Workplace Injury in St. Louis
The steps you take in the first days after an injury can make or break your claim.
- Get medical attention for anything urgent or serious.
- Report the injury to your employer in writing as soon as possible, and no later than 30 days out (more on this deadline below).
- Keep copies of your written notice and any documents you receive.
- Follow the authorized medical treatment your employer’s insurer directs.
- Document everything: how the injury happened, witnesses, symptoms, and every medical visit.
- Talk to a workers’ compensation attorney before accepting any settlement or signing anything from the insurance company.
The Two Deadlines That Drive Your Claim
Missouri imposes two separate deadlines. They work differently, and it’s worth understanding how.
1. Report your injury within 30 days
Under RSMo § 287.420, you must give your employer written notice of the time, place, and nature of the injury, along with the name and address of the injured person, no later than 30 days after the accident. Verbal notice alone generally isn’t enough.
For occupational disease or repetitive trauma, carpal tunnel, back conditions from years of lifting, illness from workplace exposure, the statute sets the trigger at 30 days after the diagnosis of the condition, not the date the problem started.
Missing this deadline is not automatically fatal. The statute itself provides an exception: a claim is not barred if the employer was not prejudiced by the failure to receive timely notice, and Missouri also recognizes a good cause exception. For occupational disease and repetitive trauma claims, the burden is on the employee to prove the employer wasn’t prejudiced. Courts apply this fact- specifically, the core purpose of the rule is giving the employer a fair chance to investigate, so late notice makes a claim significantly harder, not necessarily impossible. If you’re past 30 days, talk to an attorney rather than assuming your claim is dead.
2. File your formal claim within 2 years
Reporting your injury to your employer is not the same as filing a claim. To preserve your rights, you must file a Claim for Compensation with the Missouri Division of Workers’ Compensation within two years of the date of injury (or the last payment of benefits, whichever is later).
This is the harder deadline; once the statute of limitations runs, the claim is generally gone regardless of its merits.
Who Chooses Your Doctor? (Usually Your Employer)
This surprises many injured workers: in Missouri, the employer and its insurer have the right to choose your treating physician. If you go to your own doctor instead of the authorized provider, you may have to pay those bills yourself.
You always have the right to seek a second opinion or an independent rating at your own expense, and that outside opinion can become important evidence, especially when there’s a dispute about how serious your injury is or how much it will limit you long-term. If you believe the authorized doctor is minimizing your injury or pushing you back to work too soon, that’s a common and legitimate reason to bring in an attorney.
Workers’ Compensation Benefits in Missouri
Missouri workers’ compensation provides several distinct types of benefits.
Medical Benefits
You’re entitled to all reasonable and necessary medical treatment for your work injury, including doctor visits, hospital stays, surgery, physical therapy, prescriptions, and medical devices. There is no deductible and no co-pay; authorized costs are paid by your employer or its insurer. If you receive a bill for authorized treatment, contact the employer or insurance company immediately.
Travel reimbursement: under RSMo § 287.140, if you’re required to obtain treatment or attend a medical exam outside the local or metropolitan area of your principal place of employment, the employer must advance or reimburse your necessary and reasonable travel expenses, up to a limit of 250 miles each way. Many injured workers never claim this.
Temporary Total Disability (TTD)
If your injury keeps you completely off work while you recover, TTD pays two-thirds (66⅔%) of your average weekly wage.
How your average weekly wage is calculated depends on how you’re paid, under RSMo § 287.250:
- Paid by the week: that fixed weekly amount is your AWW
- Paid by the month: monthly wage × 12 ÷ 52
- Paid by the year: annual wage ÷ 52
- Paid by the hour, day, or output: total wages from the 13 calendar weeks before the injury ÷ 13 (or divided by the number of weeks worked, if you were employed less than 13 weeks)
Special rules apply to part-time employees, workers under 21, and those with multiple employers. Because every benefit you receive flows from this number, an incorrectly calculated AWW quietly reduces everything it’s one of the most common and costly errors in a claim.
- Maximum (injuries 7/1/2025–6/30/2026): $1,280.84 per week
- Minimum: $40 per week
- Duration: up to 400 weeks; paid until you return to work or reach maximum medical improvement (MMI)
The 3-Day Waiting Period
Compensation isn’t paid for the first three days of disability, and importantly, these are counted as days the employer is open for business, not calendar days. However, if your disability lasts more than 14 days, those first three days are paid retroactively. Miss two weeks or less, and you absorb the first three days; miss more than two weeks, and you’re paid for them after all.
Temporary Partial Disability (TPD)
If you can return to light or modified duty at reduced pay, TPD pays two-thirds of the difference between your old wages and what you can now earn. The weekly maximum matches TTD, but TPD is limited to 100 weeks.
Permanent Partial Disability (PPD)
When your injury leaves you with a lasting but partial impairment, PPD compensates you using Missouri’s Schedule of Losses (RSMo § 287.190). The formula is:
Statutory Weeks × Disability Rating (%) × Your Weekly Rate = PPD Award
Missouri assigns a set number of weeks to each body part; for example, roughly 232 weeks for a shoulder, 160 for a knee, and 400 weeks for “body as a whole” injuries such as the back, neck, or head. The maximum PPD rate for 2025–2026 injuries is $670.92 per week.
Permanent Total Disability (PTD)
If your injury permanently prevents you from returning to any reasonable employment, PTD pays two-thirds of your average weekly wage for life, subject to the same $1,280.84 weekly maximum.
Death Benefits
If a worker dies from a workplace injury, RSMo § 287.240 provides benefits to surviving dependents:
- Burial expenses: the employer pays the reasonable expense of burial, not exceeding $5,000
- Weekly death benefits: based on the employee’s average weekly earnings in the year preceding the injury, capped at $1,280.84 per week for this rate period
- Surviving spouse: generally receives benefits for life or until remarriage; on remarriage, a lump sum equal to two years of benefits
- Dependent children: generally until age 18, with continuation available for full-time students, those who served on active duty, or children incapacitated from wage earning
Dependency determinations can be contested, so surviving family members should have the claim reviewed by an attorney.
When You Can Sue Outside of Workers’ Compensation
Workers’ compensation is usually your only remedy against your employer, but that bar is not absolute. Missouri recognizes several situations where a civil lawsuit is available.
Third-party claims
If someone other than your employer caused your injury, you may have a separate personal injury claim alongside your workers’ comp benefits. Common St. Louis-area examples include a defective piece of machinery, a negligent driver who hit you while you were working, or an unsafe condition created by another contractor on a job site. These claims can recover damages workers’ comp doesn’t, including full lost wages and pain and suffering. Note that your employer’s insurer may assert a lien to be reimbursed out of a third-party recovery.
Uninsured employers
If your employer was required to carry coverage and didn’t, you may be able to sue in civil court for full damages. Operating without required coverage is also a criminal offense in Missouri.
Intentional harm by the employer
The exclusive remedy rule does not shield an employer that deliberately injures an employee.
Co-employee liability
Under RSMo § 287.120, co-employees are generally immune from suit for ordinary negligence. The exception is narrow but real: a co-employee is not released from liability where they engaged in an “affirmative negligent act that purposefully and dangerously caused or increased the risk of injury.” The Missouri Supreme Court interpreted this standard in Brock v. Dunne (2021).
Occupational disease and toxic exposure
This is an evolving area. Missouri courts have held that because mesothelioma does not result from an “accident” as the statute defines it, an affected worker could pursue a civil suit against the employer rather than being limited to the comp system. Missouri has also enacted a separate framework for enhanced mesothelioma benefits. Toxic exposure claims are highly technical and deadline-sensitive — get them reviewed by an attorney promptly.
Discrimination and retaliation claims
The exclusivity provision does not bar claims under the Missouri Human Rights Act. Separately, RSMo § 287.780 prohibits an employer from discharging or discriminating against you for filing a workers’ compensation claim, and a retaliation claim is a separate civil action from the comp claim itself one that can recover damages unavailable in the administrative proceeding.
