Oth physl fx low end ulna, l arm, subs for fx w routn heal

This code describes a follow-up encounter for a fracture of the growth plate at the lower end of the ulna in the left arm. The fracture is healing as expected without complications. This injury typically occurs in pediatric patients.

This code is appropriate for subsequent visits where a pediatric patient is receiving routine follow-up care for a left distal ulnar physeal fracture. It indicates that the fracture is progressing through a normal healing process. This would be used after the initial treatment has been rendered.

• Ensure documentation specifies "left arm" and "subsequent encounter" with "routine healing."
• Verify the fracture is specifically of the physis (growth plate) and not another part of the ulna.
• Pair with an external cause code if the mechanism of injury is relevant for the encounter.
