Oth fx lower end of right ulna, subs for clos fx w malunion

This code signifies a fracture of the lower portion of the right ulna, other than a styloid or Monteggia fracture, that is currently undergoing treatment for a malunion. A malunion indicates that the fracture has healed, but in an unsatisfactory or misaligned position.

This code is appropriate for follow-up encounters where a patient is being managed for a previously sustained, closed fracture of the distal right ulna that has healed incorrectly. This could include assessment, treatment planning for corrective surgery, or ongoing monitoring of the malunion.

• Ensure documentation clearly specifies "malunion" and the "subsequent encounter" nature of the visit.
• Verify the fracture is of the lower end of the ulna and not a styloid or Monteggia fracture.
• Confirm the fracture was initially closed; open fractures would require a different seventh character.
