Summary & Overview
CPT 24410: Humeral Shaft Osteotomy with Intramedullary Rod Fixation
CPT code 24410 denotes corrective humeral shaft osteotomy with intramedullary rod fixation, a reconstructive orthopedic procedure used to straighten improperly developed or malunited humeral shafts. This code is relevant nationally because it captures complex surgical management of humeral deformities that can affect function, rehabilitation needs, and surgical resource use across inpatient and outpatient surgical settings.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, and common billing considerations tied to this procedure. The publication also covers benchmark metrics and payment policy context where available, practical coding notes, and potential documentation elements that commonly accompany claims for corrective humeral osteotomy with intramedullary fixation.
Intended for billing professionals, orthopedic surgeons, and payer policy staff, this summary provides the clinical definition, payment-relevant framing, and a roadmap of topics addressed in the full publication: benchmarks, coding guidance, and policy updates. Data not available in the input will be noted where applicable.
Billing Code Overview
CPT code 24410 describes a surgical procedure in which the provider performs multiple wedge or segmental osteotomies of the humeral shaft to correct an improperly developed or malunited humerus and then stabilizes and straightens the bone using an intramedullary rod.
-
Service type: Orthopedic reconstructive surgery involving corrective osteotomy and internal fixation
-
Typical site of service: Hospital operating room or ambulatory surgical center where orthopedic inpatient or outpatient surgeries are performed
Clinical & Coding Specifications
Clinical Context
A typical patient is a pediatric or young-adult individual presenting with an established humeral malunion or congenital maldevelopment of the humeral shaft causing functional impairment, pain, and cosmetic deformity. The patient has failed conservative management including observation, bracing, or physical therapy and demonstrates rotational or angular deformity on clinical exam and radiographs. Preoperative workup includes history, physical exam, plain radiographs of the humerus (AP and lateral), and discussion of risks and benefits. Surgical planning involves osteotomy of the humeral shaft performed in multiple segments (multiple osteotomies) with correction of alignment and insertion of an intramedullary rod to maintain length and rotation. The procedure is typically performed under general anesthesia in an operating room within an inpatient or outpatient surgical center depending on patient age, comorbidities, and anticipated postoperative needs. Intraoperative fluoroscopy is commonly used to confirm alignment and hardware position. Postoperative care includes pain control, immobilization in a sling or humeral brace, serial radiographs to confirm consolidation, and outpatient orthopedic follow-up for hardware evaluation and rehabilitation.
