CPT Code Overview

CPT code 29515 represents the application of a short leg splint, which is used to immobilize the lower leg from the calf to the foot. This procedure is commonly performed in orthopedic settings to stabilize fractures, injuries, or other conditions affecting the lower extremity. The typical site of service for this procedure is the office, designated as Place of Service 11. Short leg splints are essential for initial management of lower leg and foot injuries, providing support and facilitating healing.

Clinical Context

A patient presents to the orthopedic office with a suspected fracture of the lower leg or foot, such as an unspecified fracture of the upper end of the tibia or foot. After clinical evaluation and imaging, the provider determines that immobilization is necessary. The provider applies a short leg splint, extending from the calf to the foot, to stabilize the injury and facilitate healing. This procedure is commonly performed by orthopedic surgeons, orthopedic trauma specialists, or emergency medicine physicians in an outpatient office setting.
