In simple words: This code covers an artificial arm and hand for people who have had their arm amputated above the elbow. It includes a custom-fitted socket and a special elbow that can be locked in place.

This code represents an arm and hand prosthesis for patients with a transhumeral (above elbow) amputation. It includes a molded double-wall socket and internal locking elbow mechanisms. The internal locking mechanism allows the patient to lock the prosthetic elbow in a flexed position, and the double-wall socket provides stability and control.

Example 1: A patient with a transhumeral amputation due to trauma requires a prosthesis with a locking elbow for increased stability during daily activities., A patient with a congenital above-elbow limb deficiency needs a custom-fitted prosthesis to improve functionality and independence., A patient undergoing revision surgery for an existing above-elbow prosthesis requires a new socket and internal locking elbow mechanism to address changes in limb volume or function.

Documentation should include the type of amputation, level of amputation, measurements of the residual limb, the type of socket and elbow mechanism used, and any modifications made to the prosthesis. Justification for medical necessity should also be included.
