Summary & Overview
CPT 24500: Nonoperative Treatment of Humeral Shaft Fracture
CPT code 24500 designates nonoperative treatment for a humeral shaft fracture — management of an upper-arm diaphyseal break without incision or manipulation. This code is used to report conservative fracture care encounters such as splinting, casting, immobilization, and clinical follow-up when no operative procedure or closed manipulation is performed. Nationally, accurate use of this code affects claims processing, quality measurement, and payment for musculoskeletal outpatient and emergency services.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of how 24500 is applied in clinical practice, common sites of service where it appears (outpatient clinics and emergency departments), and the policy and billing considerations that influence reimbursement and documentation. The publication outlines benchmarks and coding guidance where available, and highlights areas where clinical documentation must support the nonoperative nature of the encounter.
The report is organized to help billing managers, clinicians, and compliance teams understand coding boundaries for conservative humeral shaft care, common documentation needs, and how payers typically treat nonoperative fracture services. Data not available in the input will be clearly noted in relevant sections.
Billing Code Overview
CPT code 24500 describes treatment of a fracture of the humeral shaft (the upper arm bone) without incision or manipulation. This represents a nonoperative, conservative management encounter for a humeral shaft fracture.

Clinical & Coding Specifications
Clinical Context
A middle-aged adult presents to the emergency department after a fall onto the outstretched arm with localized mid‑shaft upper arm pain, swelling, and deformity. Radiographs confirm a closed fracture of the humeral shaft without neurovascular compromise. The treating orthopedist elects nonoperative management using immobilization (sling and coaptation splint) and close outpatient follow‑up. The procedure described by 24500 documents treatment of the humeral shaft fracture without open incision or manipulation in the operating room (closed treatment without manipulation), commonly performed in the ED, urgent care, or outpatient orthopedic clinic setting. Typical workflow: initial evaluation and imaging in ED → reduction attempt if indicated (unless explicitly no manipulation) → application of immobilization device and documentation of nonoperative closed treatment → discharge with analgesia, instructions, and arranged orthopedic follow‑up for serial radiographs and possible conversion to operative management if alignment is unacceptable or healing complications arise.
