Clinical & Coding Specifications

Clinical Context

A patient presents to the office with chronic musculoskeletal issues such as low back pain or knee pain, muscle weakness, and difficulty walking. The patient is referred for a work hardening or conditioning program to improve functional abilities and return to work or daily activities. After completing the initial two hours of therapy (billed with 97545), the patient requires additional therapeutic intervention.

This additional hour is documented and billed separately using CPT code 97546.
