Providing coverage for massage therapy under medical assistance plans.

SB 5507 amends Washington state law to explicitly include massage therapy as a covered service under the state's medical assistance program (Medicaid) for medically necessary treatment. This change affects Medicaid beneficiaries who require massage therapy as part of a prescribed treatment plan for conditions like chronic pain or injury recovery. The bill updates the existing coverage list (previously covering physical/occupational therapy) to add massage therapy under the same category, ensuring it qualifies for reimbursement when provided by licensed practitioners for medical purposes. It does not cover cosmetic or non-medical massage services.
