Posterior dislocation of left ulnohumeral joint, init encntr

This code signifies a complete displacement of the ulna and humerus bones at the elbow joint, specifically in a posterior direction, affecting the patient's left arm. This injury disrupts the normal articulation of the elbow, leading to significant pain and functional impairment.

This code is appropriate for the initial treatment of a patient presenting with a newly diagnosed posterior dislocation of the left elbow. It should be used when the patient is first seen for this specific injury, whether in an emergency department, urgent care, or a physician's office.

• Confirm laterality (left) and the specific joint involved (ulnohumeral).
• Ensure this is the initial encounter for this injury; subsequent care will require a different seventh character.
• Look for documentation of the mechanism of injury and any associated fractures or neurovascular compromise, which may require additional codes.
