Displ oblique fx shaft of l ulna, 7thQ

This code describes a situation where a patient has a left ulna shaft fracture, specifically an oblique type, that was initially an open fracture (Type I or II) and has now healed incorrectly, resulting in a malunion. This indicates a follow-up visit where the primary concern is the suboptimal healing of the previously open fracture.

This code is appropriate for documenting subsequent encounters for patients with a previously treated open oblique fracture of the left ulnar shaft that has healed in a misaligned position. It would be used when the patient presents for evaluation or management of this malunion, such as for pain, functional limitations, or consideration of corrective surgery.

• Ensure documentation clearly specifies "malunion" and not "nonunion" or "delayed union."
• Verify the original fracture was indeed an open fracture type I or II.
• Confirm the laterality is left and the specific bone involved is the ulna shaft.
