CPT codes are primarily used for what in physical therapy practice?

• A. Insurance billing policies.
• B. Procedure codes used to describe interventions provided to a patient.
• C. Patient educational materials.
• D. Facility safety codes.

Answer: (B)

CPT codes are standardized procedure codes used to document and bill the interventions provided to a patient. In physical therapy, these codes name the specific therapeutic services performed—such as therapeutic exercise, manual therapy, gait training, functional activities, or modalities—so the visit can be coded for reimbursement and charting. They help insurers understand exactly what was done during a session when paired with the appropriate diagnosis codes. They’re not insurance policies, patient education materials, or facility safety codes, which is why the description of describing interventions for billing and documentation fits best.
