Summary & Overview

CPT 26540: Repair of Collateral Ligament, MCP or IP Joint

CPT code 26540 represents the surgical repair of a torn collateral ligament at a metacarpophalangeal (MCP) or interphalangeal (IP) joint. This procedure is a targeted hand surgery to restore stability and function after traumatic ligament injuries to the fingers. Nationally, accurate coding for such procedures affects surgical quality measurement, reimbursement, and post-operative care coordination for hand trauma and orthopedic practices.

Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise review of clinical context for the procedure, typical sites of service, and common billing considerations. The publication summarizes benchmark fee and utilization patterns, highlights relevant policy or coverage updates that affect authorization and payment, and outlines coding and documentation elements that commonly influence claim adjudication for hand ligament repairs.

The content is intended for revenue cycle managers, orthopedic and hand surgeons, coding professionals, and policy analysts seeking a national-level overview of clinical and billing implications for CPT code 26540. Data not available in the input is noted where applicable.

Billing Code Overview

CPT code 26540 describes a surgical repair of a tear in a collateral ligament of a metacarpophalangeal (MCP) joint or an interphalangeal (IP) joint. The service is a hand/upper extremity surgical procedure focused on restoring joint stability and function after ligamentous injury.

Service type: Surgical repair of a collateral ligament
Typical site of service: Ambulatory surgical center or hospital operating room

Clinical & Coding Specifications

Clinical Context

A 34-year-old right-hand dominant carpenter presents after a fall onto an outstretched hand with immediate pain, lateral swelling, and instability of the index finger metacarpophalangeal (MCP) joint. Examination shows focal tenderness at the radial collateral ligament of the MCP joint with laxity on stress testing and limited range of motion. Radiographs exclude displaced fractures but may show small avulsion fragments. After failed conservative management with splinting and persistent instability, the hand surgeon schedules operative repair of the torn collateral ligament under regional or general anesthesia in an ambulatory surgery center or hospital outpatient department.

The clinical workflow includes preoperative evaluation (history, exam, imaging), informed consent, regional block or general anesthesia, surgical repair of the collateral ligament (direct repair, suture anchor, or imbrication), intraoperative fluoroscopy as needed, sterile dressing and immobilization, and postoperative instructions with early hand therapy referral. Typical sites of service are the ambulatory surgery center, hospital outpatient department, or inpatient operating room if comorbidities require admission.
