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

This code signifies a fracture affecting the growth plate (physis) at the lower end of the ulna bone in the left forearm, which is not further specified as Salter-Harris type I or II. The patient is in a subsequent phase of care for this injury, and the fracture is experiencing delayed healing.

This code is appropriate for follow-up encounters where a patient with a left distal ulnar physeal fracture is being monitored for healing, and the physician notes that the healing process is slower than expected. It should be used when the initial treatment has already been rendered, and the focus is on managing the delayed union of the fracture.

• Ensure documentation clearly specifies "left arm" and "delayed healing" for this subsequent encounter.
• Distinguish from initial encounters or subsequent encounters with routine healing.
• Verify that the fracture is indeed physeal and not a metaphyseal or epiphyseal fracture.
