Oth fx upr end l ulna, subs for opn fx type I/2 w routn heal

This code signifies a fracture of the upper portion of the left ulna, excluding specific types like Monteggia or olecranon, that occurred in the past and is now in a healing phase. Specifically, it refers to an open fracture (where the bone broke through the skin) classified as Type I or II, which is progressing through routine healing without complications.

This code is appropriate for follow-up encounters when a patient is receiving ongoing care for a previously sustained open fracture of the proximal left ulna. It should be used when the fracture is healing as expected and is not experiencing delayed union, nonunion, or malunion. This code would be selected for subsequent visits after the initial treatment of the open fracture.

• Ensure documentation specifies "left ulna" and "upper end" to differentiate from other forearm fractures.
• Verify the fracture was initially an "open fracture type I or II" and is now in a "subsequent encounter" for routine healing.
• Do not use this code for initial treatment or if the healing is complicated (e.g., delayed, nonunion, malunion).
