Summary & Overview
CPT 29515: Short Leg Splint, Lower Leg Immobilization
CPT code 29515 denotes the application of a short leg splint that immobilizes the lower leg from just below the knee to the foot for injuries such as fractures, dislocations, and sprains. This procedure is commonly performed in acute care settings to stabilize the limb, reduce pain, and protect soft tissues while definitive treatment is planned. Nationally, accurate use of this code supports appropriate billing for initial immobilization services across emergency departments, urgent care centers, and outpatient orthopedic clinics.
Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find an overview of clinical indications tied to the code, common service settings, and links to closely related splinting and immobilization codes. The publication also summarizes typical payer considerations and common modifiers associated with procedural billing for immobilization services.
This resource is intended to help coding staff, billing managers, and clinical leaders understand the clinical context and coding placement of CPT code 29515, compare it to related procedures, and identify where the code fits in care delivery workflows.

Clinical & Coding Specifications
Clinical Context
A 34-year-old patient presents to the emergency department after twisting the lower leg during a fall at home. The patient reports acute pain, swelling, and inability to bear weight on the affected limb. On exam there is localized tenderness over the distal tibia and ankle with swelling; neurovascular status is intact. Radiographs demonstrate an initial closed, unspecified fracture of the upper tibia on the right (S82.101A). The treating clinician determines that immediate immobilization is required prior to definitive orthopedic management. A short leg splint is applied from just below the knee to the foot to immobilize the lower leg, ankle, and foot, control pain, limit swelling, and protect the fracture during transport or while arranging definitive care.
This workflow typically involves triage and focused musculoskeletal assessment, imaging (plain radiographs), informed consent for splinting, application of the short leg splint (CPT 29515) with padding and proper molding, post-application neurovascular checks, and discharge instructions or admission for orthopedic follow-up. Providers who commonly perform this service include emergency medicine physicians, orthopedic surgeons or orthopedic trauma specialists, and urgent care clinicians in outpatient or hospital emergency department settings. Typical sites of service are the emergency department, urgent care centers, and hospital outpatient clinics managing acute musculoskeletal injuries.
