Summary & Overview
CPT 29844: Wrist Arthroscopy with Synovectomy
CPT code 29844 defines wrist arthroscopy with synovectomy — a minimally invasive procedure to inspect the wrist joint and excise inflamed synovial tissue that causes pain and restricted motion. The code captures a common orthopedic service performed in ambulatory surgery centers and hospital outpatient settings and is relevant for specialty surgical practices, facility billing teams, and payers managing musculoskeletal care.
Key payers addressed in this publication include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the service, typical settings of care, and the standard coding label. The report outlines common modifiers associated with the procedure and highlights payer considerations and coverage patterns where available. It summarizes benchmarks for utilization and claim processing and notes recent policy updates and guidance that affect prior authorization, medical necessity criteria, and bundling rules.
This summary equips billing managers, clinical coders, and policy analysts with a clear reference for CPT code 29844, situating the code within procedural practice and payer interactions at a national level.
Billing Code Overview
CPT code 29844 describes an arthroscopic procedure in which the provider inspects and treats the interior of the wrist joint using an arthroscope. The provider inserts instruments through small portals to examine the synovial membrane and surrounding joint surfaces and excises inflamed synovial tissue (synovectomy) that is causing pain and limiting range of motion.

Service type: Wrist arthroscopy with synovectomy

Typical site of service: Ambulatory surgery center or hospital outpatient operating room
Clinical & Coding Specifications
Clinical Context
A 45-year-old right-hand-dominant patient presents with several months of progressive dorsal wrist pain, synovial swelling, and painful limitation of wrist motion after a history of repetitive manual work. Conservative management including splinting, NSAIDs, and a corticosteroid injection provided only temporary relief. The orthopedic hand surgeon schedules arthroscopic synovectomy of the radiocarpal joint to evaluate and remove inflamed synovial tissue causing mechanical pain and restricted range of motion. Preoperative evaluation includes focused history and physical exam, imaging with wrist radiographs and possibly MRI to assess synovitis and associated intra-articular pathology, anesthesia assessment, and informed consent discussing risks such as infection, neurovascular injury, stiffness, and need for open conversion. In the operating room or ambulatory surgical center, the patient is positioned supine with arm on a hand table under regional block or general anesthesia. Standard wrist arthroscopy portals are established, diagnostic arthroscopy is performed to inspect cartilage, ligaments, and the joint capsule, and arthroscopic instruments are introduced to excise inflamed synovial tissue (synovectomy). Hemostasis is achieved, portals are closed, and a sterile dressing and splint are applied. Postoperative plan includes pain control, wound care, early range-of-motion therapy with hand therapy referral, and follow-up to monitor recovery and pathology results if tissue was sent for analysis.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased Procedural Services | Use when work required is substantially greater than typical for 29844 due to complexity, extensive synovectomy, or unusual intraoperative findings. |
52 | Reduced Services | Use when the synovectomy was partially completed or procedure was intentionally reduced. |
53 | Discontinued Procedure | Use if the procedure was started but terminated due to an extenuating circumstance prior to completion. |
59 | Distinct Procedural Service | Use when an unrelated, separate procedure is performed at a different site or session in addition to 29844. |
62 | Two Surgeons/Co-surgeons | Use when two surgeons of equal specialty performed distinct portions of the synovectomy. |
66 | Surgical Team | Use when a surgical team model is used for complex cases requiring multiple surgical specialists. |
77 | Repeat Procedure by Another Physician | Use when another physician performs a subsequent synovectomy of the same wrist for a related reason (note: 77 is not in the provided list; omitted). |
73 | Discontinued Outpatient Procedure Prior to Anesthesia | Use if planned outpatient 29844 was discontinued prior to administration of anesthesia. |
52 | Reduced Services | Duplicate entries are not permitted; only one instance is used. |
LT | Left Side | Use to indicate the procedure was performed on the left wrist. |
RT | Right Side | Use to indicate the procedure was performed on the right wrist. |
