Unsp physl fx low end rad, left arm, subs for fx w malunion

This code signifies a fracture of the growth plate (physis) at the lower end of the left radius, where the specific type of fracture is not documented. It indicates that the patient is in a later stage of care for this fracture, and the bone has healed in an abnormal or misaligned position.

This code is appropriate for follow-up encounters where a patient is being treated for complications arising from a previously sustained, unspecified left distal radial physeal fracture that has healed with malunion. This includes scenarios such as physical therapy for functional deficits or surgical planning to correct the malunion.

• Ensure documentation clearly states "left arm" and "malunion" for the subsequent encounter.
• Verify that the initial fracture was of the physis and not another part of the radius.
• This code requires a 7th character "P" for subsequent encounter with malunion; do not use for initial care or routine follow-up without malunion.
