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

This code signifies an unspecified growth plate fracture at the distal end of the radius in an unstated arm, where the fracture has healed in an anatomically incorrect or misaligned position. This diagnosis is made during a follow-up visit after the initial injury and treatment, specifically addressing the complication of malunion.

Use this code when a patient presents for ongoing management or evaluation of a previously sustained, unspecified distal radial physeal fracture that has healed with malunion. This applies to subsequent encounters where the focus is on the consequences or treatment of the malunion, rather than the initial injury or routine healing.

• Ensure documentation clearly states "malunion" as a complication of a previous fracture.
• Verify the encounter is "subsequent" and not the initial treatment for the fracture.
• This code is for an unspecified arm; if the laterality is known, a more specific code should be used.
