Summary & Overview
CPT 23334: Removal of Shoulder Prosthesis, Humeral or Glenoid
CPT code 23334 denotes surgical removal of a shoulder prosthesis involving the humeral or glenoid components. Nationally, this code captures a discrete revision/removal procedure commonly performed in hospital operating rooms and ambulatory surgical centers when implanted shoulder prostheses require extraction due to mechanical failure, infection, loosening, or pain. Use of a specific CPT code for prosthesis removal supports accurate tracking of revision shoulder procedures and informs quality, utilization, and payment workflows.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise view of clinical context for prosthesis removal, coding and billing considerations tied to procedure setting, and national benchmarking topics. The publication outlines typical sites of service, common billing modifiers (listed elsewhere), and which aspects of utilization and reimbursement are most relevant for providers and billing teams.
This summary prepares clinicians, coding professionals, and policy analysts to interpret use of CPT code 23334 within broader shoulder revision care pathways, understand payer inclusion, and identify where to look for policy updates or reimbursement changes. Data not available in the input is noted where applicable in subsequent sections.
Billing Code Overview
CPT code 23334 describes the removal of a prosthesis from the humeral or glenoid areas of the shoulder. This procedure involves surgical extraction of an implanted shoulder prosthetic component and is used when a humeral or glenoid prosthesis requires removal due to failure, infection, loosening, pain, or other clinical indications.

Clinical & Coding Specifications
Clinical Context
A typical patient is a 68-year-old individual with a prior shoulder arthroplasty presenting with persistent pain, loosening, recurrent infection, or prosthetic failure involving the humeral or glenoid components. The surgeon evaluates imaging (X-ray, CT) and labs (inflammatory markers, joint aspiration if infection suspected) and plans removal of the prosthetic component(s). The procedure is performed in an operating room or ambulatory surgery center under general or regional anesthesia with possible conversion to open exposure to explant the humeral stem or glenoid component. Infected cases may require staged revision with placement of an antibiotic spacer. In noninfected mechanical failure, removal may be followed by immediate revision arthroplasty or conversion to resection arthroplasty depending on bone quality and intraoperative findings. Typical workflow includes preoperative clearance, intraoperative explant of prosthesis using extraction instruments, irrigation, specimen collection for culture if indicated, and closure. Postoperative care includes pain control, wound monitoring, and coordination for staged reconstruction or physical therapy as appropriate.
