Summary & Overview
CPT 26852: Metacarpophalangeal Joint Arthrodesis with Bone Graft
CPT code 26852 denotes surgical arthrodesis of the metacarpophalangeal (MCP) joint, commonly performed to relieve pain, correct deformity, or restore stability in the hand by permanently fusing the metacarpal and phalangeal bones. The procedure frequently involves harvesting an autologous bone graft and may include internal fixation. This code is clinically important given the prevalence of hand injuries, degenerative joint disease, and reconstructive needs that affect function and workforce participation nationally.
Key payers referenced in this publication include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise depiction of what CPT code 26852 encompasses, the typical clinical and service settings for the procedure, and an outline of common billing considerations. The report also summarizes benchmark payment patterns, common modifiers used with this service, and clinical notes that affect coding and claims submission. Where specific inputs are not provided, the publication notes that data is not available in the input.
This summary is intended for billing and coding professionals, revenue cycle managers, and clinical leaders who need a clear, national-level reference on the clinical meaning and billing context of CPT code 26852.
Billing Code Overview
CPT code 26852 describes a surgical procedure to arthrodese (fuse) the metacarpophalangeal (MCP) joint. The provider surgically immobilizes the joint, often inducing bone growth at the fusion site using an autologous bone graft harvested from elsewhere in the patient’s body. Internal fixation devices may or may not be used to achieve and maintain fusion.

Service type: Surgical procedure — joint arthrodesis with bone grafting

Typical site of service: Operating room or ambulatory surgical center; procedure performed on the hand at the metacarpophalangeal joint
Clinical & Coding Specifications
Clinical Context
A 58-year-old right-hand-dominant patient presents with progressive pain, deformity, and loss of motion at the index metacarpophalangeal (MCP) joint after prior trauma and post‑traumatic arthritis. Conservative care including splinting, anti-inflammatory medication, and corticosteroid injection provided only temporary relief. The hand surgeon documents persistent joint space collapse, crepitus, and functional impairment interfering with activities of daily living and work duties.
Preoperative workflow includes history and physical, hand radiographs (AP, lateral, oblique) demonstrating joint collapse and osteophytes, informed consent discussing arthrodesis versus arthroplasty, and anesthesia evaluation. The operative plan is 26852 (MCP joint arthrodesis) performed in an ambulatory surgery center or hospital outpatient setting under regional block or general anesthesia. The surgeon prepares autogenous bone graft (typically from distal radius or iliac crest) if needed, reduces the MCP joint in functional position, and achieves fixation with internal hardware (e.g., plate, screw, K-wire) or percutaneous pinning. Postoperative workflow includes immobilization in a splint or cast, wound checks, radiographic follow-up to confirm fusion, and hand therapy as indicated for adjacent joint motion and functional recovery.
