Displ transverse fx shaft of l ulna, 7thR

This code signifies a previously sustained fracture of the shaft of the left ulna, specifically a transverse break that is currently misaligned. The initial injury was an open fracture of a severe nature (Type IIIA, IIIB, or IIIC), and the current encounter addresses the improper healing or malunion of this fracture.

This code is appropriate for follow-up encounters where a patient is being treated for complications arising from a poorly healed, severe open transverse fracture of the left ulnar shaft. This includes situations where surgical intervention or other management is being performed to correct the malunion.

• Ensure documentation clearly specifies "malunion" and not "nonunion" or "delayed union."
• Verify the laterality (left ulna) and the specific fracture type (transverse shaft) are documented.
• Confirm the original injury was an open fracture of Type IIIA, IIIB, or IIIC, as this impacts the "subsequent encounter" designation.
