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

This code signifies a fracture of the growth plate (physis) at the lower end of the right radius that is not healing properly. It indicates that the patient is presenting for follow-up care for this specific fracture, which has failed to unite.

Use this code when documenting subsequent encounters for a right distal radial physeal fracture that has been diagnosed with nonunion. This applies to situations where the patient is receiving ongoing treatment, evaluation, or management for the unhealed fracture.

• Always confirm the laterality (right arm) and the specific bone (radius) involved.
• Ensure documentation clearly states "nonunion" for the fracture healing status.
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
