HB 497 Missouri House · 2025 Regular Session

Modifies provisions relating to workers' compensation

HB 497 rewrites Missouri's workers' compensation laws to narrow coverage and clarify key terms. It defines "injury" strictly as requiring the work accident to be the "prevailing factor" (main cause), excludes injuries from normal daily life risks, and prohibits compensation for travel to/from work. The bill also limits occupational disease claims to a specific list (like mesothelioma and asbestosis) and excludes ordinary illnesses or death from natural causes. These changes directly affect Missouri workers seeking compensation and employers managing claims, shifting coverage toward more narrowly defined workplace injuries.
