Medial dislocation of left ulnohumeral joint, init encntr

This diagnosis code signifies a displacement of the ulna bone from its normal articulation with the humerus at the elbow, specifically on the inner (medial) side of the joint, affecting the patient's left arm. This type of dislocation involves the trochlear notch of the ulna losing contact with the trochlea of the humerus, resulting in significant pain and functional impairment.

Apply this code for a patient presenting with a newly diagnosed medial dislocation of the left elbow joint, typically following a traumatic event such as a fall onto an outstretched hand or a direct blow. This code is appropriate for the initial visit where the dislocation is identified and treatment is initiated.

• Ensure documentation clearly specifies "medial" dislocation and the "left" side.
• Verify this is the "initial encounter" for this specific injury; subsequent care would use a different encounter character.
• Look for associated injuries like fractures or ligamentous tears, which would require additional codes.
