CPT code 24516 represents surgical internal fixation of a humeral shaft fracture, commonly performed with an intramedullary rod and optional cerclage or locking screws. This code matters nationally because humeral shaft fractures are a frequent orthopedic injury requiring operative management to restore limb function and reduce long-term disability. Accurate coding for this procedure affects hospital and surgeon billing, resource allocation, and quality measurement for orthopedic trauma care.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for the procedure, typical sites of service, and which payers commonly reimburse for operative fracture care. The publication also summarizes benchmarks and policy-relevant considerations such as reimbursement patterns, prior authorization trends, and documentation elements that influence claims adjudication. Clinical readers will gain clarity on the procedure's intent and typical setting, while billing and policy audiences will find guidance on where to look for reimbursement policies and common coverage considerations nationally.
