Displ oblique fx shaft of unsp ulna, 7thQ

This code signifies a malunion of a previously treated oblique fracture in the shaft of an unspecified ulna, which was initially an open fracture of either Type I or Type II. Malunion indicates that the bone has healed, but in an unsatisfactory position or alignment, potentially leading to functional impairment.

Apply this code when documenting a patient's follow-up visit for an oblique ulnar shaft fracture that has healed incorrectly, and the initial injury was an open fracture. This is used for subsequent encounters where the focus is on managing the complications of the malunion, rather than the initial acute fracture treatment.

• Ensure documentation clearly states "malunion" and specifies the initial fracture as an "open fracture type I or II."
• Verify that the encounter is a "subsequent encounter" for the fracture, not the initial treatment phase.
• Confirm the fracture location is the "shaft of the ulna" and the fracture type is "oblique."
