Summary & Overview
CPT 25443: Scaphoid Prosthesis Implantation, Wrist
CPT code 25443 designates surgical implantation of an artificial prosthesis to replace the scaphoid bone in the wrist, most commonly used for nonunion scaphoid fractures or irreparable scaphoid pathology. Nationally, this code represents a specialized orthopedic hand/wrist procedure with implications for surgical resource use, device coverage, and post-operative care pathways. Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, payer coverage patterns and benchmarks where available, common billing and modifier considerations, and relevant policy or coverage highlights that affect authorization and reimbursement workflows. The publication outlines typical sites of service — outpatient surgical centers and hospital operating rooms — and situates the code within hand and wrist surgical services. Data not provided in the input are noted as unavailable where relevant. This summary equips clinicians, coding staff, and policy analysts with a clear reference to the code’s clinical intent, payer landscape, and the aspects of billing and policy most likely to influence use of CPT code 25443.
Billing Code Overview
CPT code 25443 describes a surgical procedure in which an artificial prosthesis is fitted to replace the wrist’s scaphoid bone. This intervention is typically performed for a nonhealing (nonunion) scaphoid fracture or when native scaphoid anatomy is no longer salvageable.
-
Service type: Surgical implantation of a small joint prosthesis to restore wrist biomechanics
-
Typical site of service: Outpatient surgical center or hospital operating room
Clinical & Coding Specifications
Clinical Context
A 34-year-old right-handed construction worker presents with persistent radial-sided wrist pain and limited range of motion 6 months after an initial scaphoid fracture treated nonoperatively. Imaging (plain radiographs and CT) demonstrates nonunion and progressive collapse of the scaphoid with early carpal instability but preserved midcarpal cartilage. After failed conservative care and a trial of immobilization, the hand surgeon elects to perform scaphoid prosthetic replacement to restore carpal alignment and relieve pain.
Preoperative workflow includes history and physical, informed consent discussing risks and benefits, preop imaging review (radiographs and CT, possibly MRI to assess cartilage), anesthesia evaluation for general or regional block, and scheduling the patient to an ambulatory surgery center. Intraoperative steps include a dorsal or volar approach to the wrist, excision of the nonunited scaphoid, preparation of the prosthetic footprint, trialing and implantation of the scaphoid prosthesis, assessment of carpal kinematics and stability, and wound closure. Postoperative care includes immobilization in a splint or cast, pain control, early hand therapy per surgeon protocol, and follow-up radiographs to confirm implant position and monitor for complications such as implant loosening, infection, or persistent instability.
