In simple words: This code covers an artificial lower arm and hand for someone who has had their arm amputated at the elbow. It has a custom-fit socket that can be adjusted for growth or swelling, and hinges at the elbow that can be locked in different positions.

This code describes a lower arm and hand prosthesis for patients with an amputation through the elbow joint. It includes a molded socket with an expandable interface, allowing for adjustments due to growth or changes in limb volume, and outside locking hinges for the forearm component. The expandable interface allows the patient to change the prosthesis easily.

Example 1: A 10-year-old child with a congenital elbow disarticulation requires a new prosthesis to accommodate growth., An adult patient with a recent traumatic elbow disarticulation requires a prosthesis with an adjustable socket for volume fluctuations during the healing process., An adult patient with a stable elbow disarticulation requires a replacement prosthesis with a durable, locking hinge mechanism for enhanced stability.

Medical records documenting the amputation level, the need for a prosthesis, and any specific requirements for socket fit and hinge type.
