Workers' compensation; mental health-related injuries; first responders; service weapon; CLEET certification; effective date.

HB 1842 modifies Oklahoma's workers' compensation rules for first responders (law enforcement officers, full-time firefighters, and EMTs) who develop mental health conditions like PTSD without a physical injury. It limits mental health disability benefits to 52 weeks, requires diagnosis by a licensed psychiatrist or psychologist, and caps medical treatment costs at $10,000. Employers must suspend CLEET certification and collect service weapons during leave, while providing health insurance coverage during temporary disability. Permanent disability benefits up to $50,000 are available if a first responder cannot return to work after maximum medical improvement.
