Unsp fx upr end l ulna, 7thR

This code signifies an unspecific fracture of the upper portion of the left ulna that is currently healing, but with an unsatisfactory alignment of the bone fragments (malunion). This particular fracture was initially an open fracture, meaning the skin was broken, and was classified as a severe open injury (Type IIIA, IIIB, or IIIC).

Use this code when documenting follow-up care for a patient with a previously treated, severe open fracture of the proximal left ulna that has healed incorrectly. This applies to situations where the malunion is being addressed or monitored during a subsequent encounter.

• Ensure documentation clearly specifies "malunion" and the initial open fracture type (IIIA, IIIB, or IIIC).
• Verify the fracture location is the "upper end" of the ulna and laterality is "left."
• This code is for subsequent encounters; an initial encounter for the fracture would use a different code.
