Nondisp fx of coronoid pro of l ulna, 7thQ

This code signifies a fracture of the coronoid process on the left ulna that was initially an open fracture (Type I or II) and has since healed incorrectly, resulting in malunion. The fracture itself was not displaced at the time of the initial injury.

Apply this code when documenting follow-up care for a patient who previously sustained an open, nondisplaced coronoid process fracture of the left ulna and is now presenting with complications of malunion. This would be used during subsequent encounters after the initial treatment phase.

• Ensure documentation clearly specifies "left ulna" and "coronoid process" along with "nondisplaced" and "malunion."
• Verify the original injury was an "open fracture type I or II" to justify using this specific subsequent encounter code.
• Distinguish from nonunion (failure to heal) or delayed union (slow healing) as this code specifically indicates malunion (healed incorrectly).
