CO HB1229

Requires mental impairment claims under workers' compensation to be proven by testimony of a licensed psychiatrist or psychologist rather than just a physician.

Defines "mental impairment" to include disability from a psychologically traumatic event outside a worker's usual experience that would cause significant distress, or post-traumatic stress disorder diagnosed after exposure to deadly force attempts, witnessing deaths, or witnessing serious bodily injuries.

Excludes mental impairment claims resulting from disciplinary actions, work evaluations, job transfers, lay-offs, demotions, promotions, terminations, retirement, or similar good-faith employer actions.

Requires mental impairment must arise primarily from the claimant's occupation and place of employment to be compensable.

Takes effect July 1, 2018, subject to referendum petition, and applies to injuries sustained on or after the effective date.
