Summary & Overview
CPT 26860: Interphalangeal Joint Immobilization (Arthrodesis)
CPT code 26860 represents surgical immobilization (arthrodesis) of an interphalangeal joint, a targeted procedure to relieve pain and restore stability in end-stage osteoarthritis or similar destructive joint disease of the fingers or toes. Nationally, this code matters because it captures a discrete, often elective reconstructive procedure that affects surgical utilization, post-operative care pathways, and device-use reporting in musculoskeletal care.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find clinical context for when interphalangeal joint fusion is performed, the typical settings for service delivery, and the implications for coding and claims submission. The publication summarizes common modifiers and provides national benchmarking context where available.
This report is intended to help coding professionals, revenue cycle staff, and policy analysts understand billing considerations tied to a focused hand/foot surgical procedure, its place in musculoskeletal care, and payer coverage patterns. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 26860 describes a surgical procedure to immobilize an interphalangeal joint, performed with or without fixation devices. The procedure is typically used to relieve pain and stabilize an interphalangeal joint, often for patients with end-stage osteoarthritis or other debilitating joint conditions of the fingers or toes.
Service Type: Surgical arthrodesis / joint immobilization
Typical Site of Service: Hospital outpatient department, ambulatory surgery center, or inpatient operating room, depending on clinical complexity and patient factors.

Clinical & Coding Specifications
Clinical Context
A typical patient is a 68-year-old retired gardener with progressive pain, stiffness, and deformity of the distal interphalangeal joint of the right index finger due to end-stage osteoarthritis. Conservative measures including activity modification, splinting, nonsteroidal anti-inflammatory drugs, and corticosteroid injection provided only short-term relief. The hand surgeon evaluates radiographs showing joint space loss, osteophyte formation, and subchondral sclerosis. After shared decision-making, the surgeon schedules surgical arthrodesis of the affected interphalangeal joint to relieve pain and restore a stable, functional finger.
The clinical workflow includes preoperative assessment and medical clearance, targeted local or regional anesthesia (digital block or field block) in an ambulatory surgery center or hospital outpatient department, operative joint preparation and cartilage removal, alignment and fixation of the interphalangeal joint with or without implants (screws, K-wires), intraoperative fluoroscopic confirmation of position, sterile dressing and postoperative immobilization (splint or cast), and routine postoperative visits for wound check and progressive rehabilitation. Typical site of service: ambulatory surgery center or hospital outpatient surgery unit. Service type: minor hand surgical procedure (arthrodesis / joint fusion).
