Ulnohumeral (joint) sprain of right elbow, initial encounter

This code signifies a ligamentous injury to the ulnohumeral joint of the right elbow, often involving the medial collateral ligament complex. It indicates a stretching or tearing of these stabilizing structures, leading to pain, swelling, and restricted movement in the elbow.

Apply this code for patients presenting with a new injury to the right elbow consistent with a sprain of the ulnohumeral joint. This typically occurs due to hyperextension, valgus stress, or a fall onto an outstretched hand. It is appropriate for the initial evaluation and treatment of such an injury.

• Ensure documentation clearly specifies the right elbow and the initial encounter for the injury.
• Distinguish from other elbow sprains (e.g., radiohumeral) or fractures.
• Look for keywords like "sprain," "ligamentous injury," or "valgus instability" of the ulnohumeral joint.
