Oth physl fx lower end rad, unsp arm, subs for fx w nonunion

This code signifies a fracture of the growth plate (physis) at the lower end of the radius bone in the forearm, where the specific arm (left or right) is not documented. It indicates that the fracture is not healing properly, resulting in a nonunion, and the patient is presenting for follow-up care after the initial treatment.

This code is appropriate for subsequent encounters when a patient with an unspecifed physeal fracture of the distal radius is diagnosed with a nonunion. This would include situations where the patient is receiving ongoing treatment, monitoring, or evaluation for the failed healing of the fracture.

• Ensure documentation clearly states "nonunion" for the fracture.
• Confirm this is a subsequent encounter, not the initial treatment.
• If the laterality (left or right arm) is documented, a more specific code should be used.
