WI AB158

Expands eligibility for PTSD-related worker's compensation benefits to emergency medical responders, EMS practitioners, volunteer firefighters, correctional officers, emergency dispatchers, coroners, coroner staff, medical examiners, and medical examiner staff

Removes the requirement that these workers demonstrate "unusual stress of greater dimensions than day-to-day emotional strain" to qualify for PTSD benefits when no physical injury accompanies the mental injury

Applies the same evidentiary standard currently used for law enforcement officers and full-time firefighters, requiring only preponderance of evidence and a diagnosis by a licensed psychiatrist or psychologist

Limits compensation for mental injuries resulting in PTSD diagnosis (without accompanying physical injury) to three times in an individual's lifetime, regardless of employer changes

Takes effect when the Commissioner of Insurance approves new worker's compensation insurance rates after the bill's passage
