Billing Code Overview
CPT code 97035 designates therapeutic ultrasound, a physical therapy modality used to promote tissue healing, reduce pain, and relax or strengthen muscles affected by strain or injury.

The procedure involves application of ultrasound energy to targeted soft-tissue structures to facilitate healing responses and symptom relief. The coding reflects a modality-based treatment rather than a hands-on therapeutic exercise or manual therapy session.
