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

This code indicates a right distal radial physeal fracture that was not specified as Salter-Harris type, and is currently experiencing nonunion. The patient is in a subsequent phase of care for this fracture, meaning the initial treatment has already occurred. Nonunion signifies that the bone fragments have failed to heal completely after a reasonable period.

Apply this code for follow-up encounters of a right distal radial growth plate fracture where the specific Salter-Harris classification was not documented, and the physician explicitly diagnoses nonunion. This is appropriate when the patient is receiving ongoing management for the unhealed fracture, such as considering revision surgery or prolonged immobilization.

• Ensure documentation clearly states "nonunion" for the right distal radial physeal fracture.
• Verify the encounter is for subsequent care, not initial treatment or routine follow-up without complications.
• Confirm the fracture location is the lower end of the radius and laterality is right.
