CPT Code Overview

CPT code 29049 describes the application of a figure‑of‑eight cast, a procedure commonly performed in orthopedic and general clinical settings to immobilize and support injuries, particularly fractures of the upper extremity. This service is typically provided in a physician office or outpatient facility, ensuring prompt stabilization and comfort for patients with musculoskeletal injuries. The figure‑of‑eight cast technique is designed to maintain proper alignment and facilitate healing, making it a standard approach in fracture management.

Clinical & Coding Specifications

Clinical Context

A patient presents to the physician office or outpatient facility with a closed fracture of the upper extremity, such as the shaft of the humerus or the lower end of the radius. The orthopedic provider evaluates the injury, confirms the diagnosis, and determines that immobilization is required. A figure‑of‑eight cast is applied to stabilize the fracture and promote healing. The procedure is performed by an orthopedic surgeon, trauma specialist, or hand surgeon, depending on the injury location. The cast application is documented, and the appropriate laterality modifier is selected based on the affected limb.

Coding Specifications
