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

This code signifies an unspecific growth plate fracture located at the distal end of the right ulna. The "subsequent encounter" indicates that the patient is receiving ongoing care for this fracture, and "nonunion" specifies that the bone fragments have failed to heal together after a typical healing period.

This code is appropriate for follow-up visits where a patient is being managed for a previously diagnosed physeal fracture of the right distal ulna that has not shown signs of healing. It would be used when evaluating treatment options for nonunion, such as surgical intervention or continued conservative management.

• Ensure documentation clearly states "nonunion" and specifies the right arm.
• Verify that the encounter is for follow-up care, not the initial injury.
• Confirm the fracture is indeed physeal (growth plate) and at the lower end of the ulna.
