Clinical & Coding Specifications
Clinical Context
A patient presents to an outpatient physical therapy clinic following orthopedic surgery, such as a knee or back procedure. The patient is experiencing post-operative pain that is interfering with their rehabilitation progress. The physical therapist evaluates the patient and determines that low-level laser therapy is appropriate to help reduce pain and facilitate recovery. The therapist applies the laser modality to one or more affected areas as part of the patient's physical therapy plan of care. This service is typically performed in an outpatient setting and documented under the physical therapy plan, with the goal of reducing pain and improving function.
