Revise workers' compensation law to cover PTSD for first responders and others

This bill expands Montana's workers' compensation system to cover posttraumatic stress disorder for first responders, including firefighters, law enforcement officers, dispatchers, and prison employees. Under the new provisions, these workers can file claims if a qualified diagnosis confirms their PTSD resulted from an emergency event occurring during their official duties, excluding stress caused by personnel actions like disciplinary measures or job changes. The legislation amends existing state statutes to create an exception to Montana's general rule against compensating mental-mental claims, specifically recognizing the unique risks faced by first responders. Coverage applies to both professional and volunteer responders who act in an official capacity during emergency responses.
