CPT code 24370 represents surgical revision of a previously implanted total elbow prosthesis when one component—either the humeral or ulnar element—has failed. The procedure typically includes removal of the failed component, implantation of a replacement component, and may include placement of donor bone graft material. This code matters nationally because revision arthroplasty carries higher resource use, complex perioperative management, and implications for device surveillance and payer coverage policies.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a clear clinical description of the service, expected sites of care, and the context for utilization and coverage considerations. The publication presents benchmarks and payment policy context where available, highlights common billing practices and relevant modifiers, and outlines clinical factors that influence service setting and resource needs. The material is designed for clinicians, coding staff, and policy analysts seeking concise guidance on the purpose and scope of CPT code 24370, operational considerations for delivering the service, and areas where payer policies and utilization drivers commonly intersect.
