Oth physl fx low end rad, right arm, subs for fx w malunion

This code signifies a follow-up encounter for a fracture of the growth plate at the lower end of the right radius, which has healed improperly, resulting in a malunion. This indicates that the bone fragments have united in an anatomically incorrect position, potentially leading to functional impairment or deformity.

Use this code when a patient presents for ongoing management or evaluation of a previously treated right distal radial physeal fracture that has healed with malunion. This applies to situations where the malunion is the primary focus of the current encounter, such as for assessment of range of motion, pain, or consideration of corrective surgery.

• Ensure documentation clearly specifies "malunion" and the "subsequent encounter" status for the right lower radius physeal fracture.
• Do not use this code for initial treatment or for nonunion; a different code would be appropriate for those scenarios.
• Verify laterality (right arm) is explicitly documented to support the use of this specific code.
