4 Steps to Report a Workplace Injury in Missouri

The steps you take in the first 24–72 hours after a workplace injury have an outsized effect on your workers' compensation claim. Follow this process to protect your rights from the start.

  1. 1
    Assess the injury and get immediate medical care Seek medical attention right away. Your health comes first, and medical documentation also creates a critical paper trail for your claim. Missouri law (RSMo 287.140) gives your employer the right to direct you to their chosen medical provider — but in a true emergency, go to the nearest emergency room first.
  2. 2
    Notify your employer in writing — within 30 days Missouri law requires you to notify your employer of a workplace injury within 30 days (RSMo 287.420). Verbal notice is not enough — put it in writing and keep a copy. Include your name, date of injury, location, how it happened, and the body part(s) affected. Give this to your supervisor or HR department and keep a copy for yourself.
  3. 3
    Document everything Photograph your injuries, the accident scene, and any equipment involved. Gather names and contact information for any witnesses. Keep every medical bill, prescription receipt, and treatment record. This documentation is what wins and loses workers' comp claims — and it's the foundation of collecting evidence for your case.
  4. 4
    Contact a workers' compensation attorney before signing anything Before you sign any paperwork from your employer or their insurance company, speak with an attorney. Insurance adjusters are trained to minimize payouts — what looks like a routine form may contain language that limits your rights. Chris Miller handled claims from the state side at the Missouri DWC; he knows exactly how insurance companies use early paperwork against injured workers.

Missouri Workers' Compensation Reporting Requirements

Under RSMo 287.420, injured workers in Missouri must report workplace injuries to their employer within 30 days of the injury — or within 30 days of discovering that a condition is work-related (for occupational diseases).

Why your attorney's background matters

Why Your Attorney's Background Matters When Reporting an Injury

Most workers don't know what happens after a workplace injury report is filed. They submit paperwork and wait. Meanwhile, the employer's insurance company is building a file — looking for inconsistencies, gaps in treatment, or missing documentation they can use to deny or minimize the claim.

Before representing injured workers, Chris Miller served as a government attorney in the Missouri Department of Labor and administered the Missouri Division of Workers' Compensation — the state administrative body where disputed workers' compensation claims are heard and decided. He's seen exactly how claims are evaluated, what documentation gaps get exploited, and what early mistakes cost workers thousands of dollars down the road.

At Bur Oak Injury Law, the reporting process is handled right from the start: written notice drafted correctly, medical documentation secured, employer obligations tracked, and insurance company tactics anticipated before they become problems. One attorney — no handoffs to associates or paralegals — your case stays with Chris from the first report to the final outcome.

Workers' Compensation Claims in Missouri: What Injured Workers Need to Know

Workers' compensation in Missouri is administered through the Missouri Division of Workers' Compensation (DWC), a state agency that handles disputed claims, monitors employer compliance, and adjudicates contested cases. When an injured worker and an employer's insurance company cannot resolve a claim, it goes to a DWC administrative law judge for hearing.

Missouri's workers' compensation system covers most employees — full-time, part-time, and seasonal workers — with limited exceptions for certain agricultural workers and domestic employees. Independent contractors are generally not covered, though misclassification is a common insurance company defense that an experienced attorney can challenge.

The workers' compensation process in Missouri typically involves: filing a claim for compensation (Form WC-21) with the DWC, attending a conference with a DWC mediator, and if unresolved, proceeding to a formal hearing before an administrative law judge. Injured workers have the right to be represented by an attorney throughout this process. Attorney fees in Missouri workers' comp cases are capped by statute and paid from any settlement or award — not out of pocket.

Common reasons claims are denied in Missouri include: late reporting (beyond the 30-day window), disputed causation (the employer claims the injury wasn't work-related), pre-existing condition defenses, and independent contractor misclassification. Each of these defenses can be effectively challenged with the right legal representation.

Common questions

Frequently Asked Questions: Reporting a Workplace Injury in Missouri

Missouri law (RSMo 287.420) requires you to notify your employer within 30 days of the injury — or within 30 days of discovering that a condition is work-related. Missing this deadline can result in your claim being denied. Always report in writing and keep a copy.
Late reporting does not automatically bar your claim, but it gives the insurance company a powerful argument to deny it. If you missed the 30-day window, contact a workers' compensation attorney immediately. There are legal arguments available — such as the employer having actual knowledge of the injury — that can preserve your claim even with late notice.
No. Missouri law (RSMo 287.780) prohibits employers from retaliating against workers who report injuries or file workers' compensation claims. If you've been fired, demoted, or otherwise treated differently after reporting an injury, you may have an employer retaliation claim in addition to your workers' comp claim.
You don't legally need a lawyer to file the initial report, but having one involved from the start dramatically improves outcomes. Insurance companies begin building their defense file the moment they receive notice of an injury. An experienced workers' compensation attorney ensures your documentation is complete, your rights are protected, and you don't inadvertently say or sign something that limits your benefits.
