Summary & Overview
CPT 29843: Arthroscopic Irrigation and Debridement of Wrist Joint
CPT code 29843 represents arthroscopic irrigation and debridement of the wrist joint for suspected or confirmed infection. Nationally relevant, this procedure addresses joint sepsis and contaminated intra-articular debris through minimally invasive visualization, lavage, and drainage. It is performed by orthopedic or hand surgeons in surgical settings and can be pivotal in preventing joint destruction and systemic spread of infection.
Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, typical sites of service, common modifiers and payer considerations (where available), and references to coding and billing practice. The publication outlines benchmarks and reimbursement context, summarizes typical clinical indications, and highlights documentation elements that commonly affect coding and coverage determinations.

Billing Code Overview
CPT code 29843 describes arthroscopic irrigation and debridement of the wrist joint to inspect and clean a suspected area of infection. The provider uses an arthroscope to visualize the internal structures of the wrist, performs lavage to wash out the joint, and drains infectious debris to reduce contamination and promote joint recovery.
Service Type: Arthroscopic diagnostic and therapeutic procedure
Typical Site of Service: Ambulatory surgical center or hospital operating room, performed by an orthopedic or hand surgeon experienced in wrist arthroscopy.
Clinical & Coding Specifications
Clinical Context
A patient in their early 50s presents to the emergency department with a 48-hour history of increasing pain, swelling, erythema, and limited range of motion of the wrist after recent minor penetrating trauma. Vital signs demonstrate low‑grade fever and localized warmth over the wrist. Laboratory markers show elevated white blood cell count and C‑reactive protein. Radiographs are obtained to exclude fracture. Given concern for septic arthritis or pyarthrosis of the wrist joint, the orthopaedic hand surgeon schedules an urgent arthroscopic irrigation and debridement of the wrist.
Preoperative workflow includes informed consent, antibiotic administration per hospital protocol, surgical time-out, and operative planning for arthroscopy with irrigation and drainage. Intraoperatively the provider uses an arthroscope to inspect the radiocarpal and midcarpal compartments, performs synovial inspection and culture sampling, copiously irrigates the joint, and removes purulent material and inflamed synovium. Postoperative care includes antibiotic therapy guided by culture results, wound checks, and hand therapy as needed. Typical site of service is the hospital operating room or ambulatory surgical center for urgent procedures, with recovery in PACU and possible inpatient admission for intravenous antibiotics and monitoring.
