Workers' Comp Denied in Missouri? How to Appeal Through the LIRC and ALJ
Missouri's workers' compensation system is administered by the Division of Workers' Compensation (DWC) within the Department of Labor and Industrial Relations (DLIIR). Disputed claims are heard by Administrative Law Judges (ALJs), with appeals to the Labor and Industrial Relations Commission (LIRC). Missouri significantly reformed its workers' comp law in 2005, making it more difficult to prove causation — understanding the current standards is critical.
Common Reasons Missouri Workers' Comp Claims Are Denied
- Work-relatedness disputed: Missouri's 2005 reform requires that the work accident be the "prevailing factor" in causing the injury — a higher bar than many states.
- Late reporting: Missouri requires you to report an injury to your employer within 30 days of the accident.
- Pre-existing condition: Missouri's "prevailing factor" standard makes pre-existing condition defenses especially potent.
- No witnesses: Claims for occupational disease and repetitive stress without corroboration are routinely denied.
- Missed IME: Failure to attend a required medical examination can result in suspension of benefits.
- Return-to-work dispute: Insurers terminate temporary total disability when they assert light duty is available.
Missouri's "Prevailing Factor" Standard
Unlike states that use an "arising out of" or "contributing factor" standard, Missouri requires that the work accident or occupational exposure be the prevailing — meaning primary and dominant — cause of the injury. This standard was enacted to reduce the number of occupational disease and repetitive stress claims. Building strong medical evidence that establishes the work injury as the prevailing cause is essential.

The Role of a Workers' Comp Attorney in Missouri
