Dislocation of distal end of left ulna, subsequent encounter

This code signifies a dislocation of the far end of the ulna bone in the left forearm, specifically when the patient is receiving follow-up care for this injury. This type of injury involves the complete separation of the ulnar head from its normal articulation, typically at the wrist joint.

Apply this code for patients presenting for routine follow-up appointments, cast changes, physical therapy, or other ongoing treatment related to a previously diagnosed and treated dislocation of the distal left ulna. This includes situations where the patient is still in the healing phase or undergoing rehabilitation.

• Ensure the encounter is for subsequent care, not the initial treatment of the dislocation.
• Verify the laterality is specifically for the left ulna.
• Confirm the dislocation is of the distal end, not another part of the ulna.
