Unsp physl fx low end humer, r arm, subs for fx w malunion

This code indicates a fracture of the growth plate at the lower end of the right humerus, where the bone has healed in an abnormal alignment. This particular code is used when the patient is receiving follow-up care for this malunited fracture.

This code is appropriate for documenting ongoing treatment, such as physical therapy, casting changes, or surgical planning, for a previously diagnosed and malunited physeal fracture of the distal right humerus. It signifies that the initial injury has already occurred and the current encounter addresses the complication of improper healing.

• Ensure documentation specifies "malunion" and the "subsequent encounter" for accurate code selection.
• Verify laterality (right arm) is clearly documented.
• Do not use for initial injury or for nonunion; specific codes exist for those scenarios.
