Ulnohumeral (joint) sprain of unspecified elbow, init encntr

This code signifies a sprain of the ulnohumeral joint, which is the primary articulation between the ulna and humerus in the elbow, without specifying which elbow is affected. It indicates damage to the ligaments supporting this joint, typically due to overstretching or tearing.

Use this code for a patient presenting with an acute elbow injury where the ulnohumeral ligaments are sprained, and the specific side (left or right) of the injury is not documented. This is appropriate for the initial evaluation and treatment of such an injury.

• Ensure documentation clearly states a sprain of the ulnohumeral joint.
• Only use this code when the laterality (left or right elbow) is truly unspecified in the medical record.
• The "A" suffix indicates an initial encounter for this injury; subsequent encounters will require different seventh characters.
