Oth fx upper end of r ulna, subs for clos fx w routn heal

This code signifies a follow-up visit for a patient who sustained a non-specific fracture to the upper portion of their right ulna. The fracture is closed, meaning the skin remains intact, and is currently healing as expected without complications.

Apply this code for subsequent encounters where a patient is receiving ongoing care for a previously diagnosed closed fracture of the proximal right ulna. This is appropriate when the fracture is progressing through a normal healing trajectory. Do not use for initial treatment or if healing is delayed or complicated.

• Ensure the documentation specifies a "subsequent encounter" and "routine healing" for a closed fracture.
• Verify the laterality is "right" and the bone involved is the "ulna," specifically the "upper end."
• Distinguish from codes indicating delayed union, nonunion, or malunion, which would require different seventh characters.
