Unsp physl fx low end ulna, r arm, subs for fx w malunion

This code signifies a fracture of the growth plate (physis) at the distal end of the right ulna, where the specific type of physeal injury is not documented. It indicates that the patient is presenting for follow-up care of this fracture, and the bone fragments have healed in an unsatisfactory alignment, known as malunion.

Apply this code when a patient with a previously diagnosed, unspecified physeal fracture of the right distal ulna is seen for ongoing management of a malunion. This would typically occur during a subsequent visit after the initial treatment, where imaging confirms the improper healing.

• Ensure documentation clearly states "malunion" and specifies the "right ulna" and "physeal fracture."
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
• If the specific Salter-Harris classification of the physeal fracture is known, a more specific code should be used.
