Ulnohumeral (joint) sprain

This code represents a sprain of the ulnohumeral joint, which is the primary articulation within the elbow joint between the ulna and the humerus. It signifies an injury to the ligaments supporting this specific part of the elbow, typically resulting from overstretching or tearing.

Use this code when documentation specifies a sprain affecting the ulnohumeral joint of the elbow. This is appropriate for injuries sustained from hyperextension, twisting, or direct trauma to the elbow where ligamentous damage to this specific joint is diagnosed.

• Ensure the documentation explicitly states "ulnohumeral joint" or clearly indicates the specific ligaments involved in this articulation (e.g., medial collateral ligament).
• Differentiate from other elbow sprains (e.g., radiohumeral, radioulnar) which have distinct codes.
• Consider an external cause code (E-code) to describe the circumstances of the injury, if available.
