MO HB614

Repeals and reenacts section 287.067, RSMo, relating to the definition and compensability of occupational diseases under workers' compensation law.

Requires occupational exposure to be the "prevailing factor" (primary factor in relation to any other factor) in causing both the medical condition and disability for compensability.

Recognizes repetitive motion injuries, industrial noise-induced hearing loss, radiation disability, and contagious or communicable diseases as occupational diseases.

Extends psychological stress coverage as an occupational disease to paid peace officers of police departments certified under chapter 590, in addition to firefighters, if a direct causal relationship is established.

Establishes liability rules for repetitive motion injuries occurring within three months of employment, making the prior employer liable if exposure with that employer was the prevailing factor in causing the injury.
