The bill amends Section 2 of the Administrative Workers Compensation Act in Oklahoma, updating and clarifying key definitions and statutory language related to workers' compensation. Significant changes include an expanded definition of "carrier" to include self-insured entities, a broader definition of "child" to include posthumous children and stepchildren, and the introduction of "continuing medical maintenance," which pertains to necessary medical treatment after reaching maximum medical improvement. The bill also revises the definition of "employee" to include members of the Oklahoma National Guard and certain volunteer workers while specifying exclusions for low payroll agricultural workers and certain independent contractors.

Furthermore, the bill modernizes language by updating references to the "State of Oklahoma" to "this state" and changing "this act" to "the Administrative Workers Compensation Act." It clarifies definitions such as "major cause" and "permanent disability," outlines workplace misconduct, and specifies criteria for determining permanent disability ratings based on objective findings and established medical guidelines. The bill also addresses various types of disabilities and the role of the Oklahoma Workers Compensation Commission in determining the status of surviving spouses. It is set to take effect on November 1, 2025, following its passage in the Senate on March 26, 2025.
