Summary & Overview
CPT 29847: Arthroscopic Wrist Reduction with Screw Fixation
CPT code 29847 represents arthroscopic evaluation and operative reduction of wrist fractures or chronic carpal instability with insertion of screws for stabilization. This code captures a minimally invasive orthopedic procedure that combines diagnostic arthroscopy with therapeutic reduction and internal fixation. Nationally, the code is relevant for surgical management of complex wrist fractures and instability where arthroscopic guidance and screw fixation are used to restore anatomy and preserve wrist function.
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 and typical sites of service, benchmarks for utilization and payment where available, and notes on coding considerations and related procedural categories. The summary highlights what stakeholders need to know about service classification and clinical indications without making clinical recommendations.
The publication will help clinicians, coders, and policy analysts understand the procedural intent of CPT code 29847, typical care settings, and the payer landscape relevant to coverage and billing. Data not available in the input is noted where necessary.
Billing Code Overview
CPT code 29847 describes an arthroscopic wrist procedure in which the provider inspects the intra‑articular tissues of the wrist with an arthroscope, introduces additional instruments to reduce or realign fractured or unstable carpal bones, and inserts screws to stabilize the bones. The procedure involves visualization and operative fixation performed through arthroscopic portals.
-
Service type: Arthroscopic wrist repair with internal fixation (operative arthroscopy with screw fixation)
-
Typical site of service: Hospital outpatient department or ambulatory surgery center with arthroscopy-capable operative suite
Clinical & Coding Specifications
Clinical Context
A 42-year-old right-hand–dominant construction worker presents with persistent wrist pain, swelling, and mechanical instability after a fall onto an outstretched hand six weeks earlier. Imaging demonstrates a displaced distal radius fracture with intra-articular extension and concomitant scapholunate ligament disruption leading to carpal instability. Conservative management with splinting and analgesia failed to restore alignment and stability.
The orthopedic hand surgeon schedules arthroscopic-assisted reduction and internal fixation of the wrist. In the operating room under regional block and general anesthesia, the surgeon introduces an arthroscope into the radiocarpal joint to evaluate cartilage surfaces and confirm ligament injury. Through accessory portals, instruments are used to debride fracture hematoma, perform closed reduction under direct visualization, and insert guide wires and cannulated screws to stabilize the distal radius and scapholunate interval. Postoperative care includes immobilization in a splint, analgesia, and early hand therapy per protocol. Typical documentation includes preoperative diagnosis, informed consent, procedure details (arthroscopy portals, findings, fixation hardware used), estimated blood loss, complications, and disposition.
