The Department of Labor & Industries filed a CR-102 proposed rulemaking with the Office of the Code Reviser.

This rulemaking proposes to amend WAC 296-21-270. Labor & Industries’ (L&I) rules don’t currently allow master’s level therapists (MLTs) to treat injured workers. L&I initiated a pilot to determine how MLTs can best be incorporated into the workers’ compensation setting. The amended section will allow MLTs to treat workers for behavioral health and mental health conditions.

A virtual public hearing has been scheduled to solicit comments on proposed rulemaking related to the MLT pilot. All testimony and written comments become part of the public record.
