CPT® Code 24343

The procedure described by CPT® Code 24343 involves the surgical repair of the lateral collateral ligament (LCL) of the elbow using local tissue. The LCL, also known as the radial collateral ligament, plays a crucial role in stabilizing the elbow joint by connecting the lateral epicondyle of the humerus to the annular ligament of the radius. This ligament helps maintain the proper alignment of the radial head within the ulna's trochlear notch, ensuring smooth movement of the elbow. Injuries to the LCL can occur due to acute trauma, such as a fall or direct impact, but are more frequently associated with chronic conditions, particularly repetitive stress injuries like tennis elbow. The surgical repair involves making an incision over the lateral aspect of the elbow, allowing access to the damaged ligament. The procedure includes careful dissection to expose the joint capsule and the LCL, followed by debridement of any damaged tissue. The ligament is then reattached to the humerus using sutures, and local tissue, often a split anconeus fascia transfer, is utilized to reinforce the repair. This approach aims to restore the stability and function of the elbow joint, facilitating recovery and return to normal activities.
