Nondisp oblique fx shaft of l ulna, 7thQ

This code describes a situation where a patient has a non-displaced fracture of the shaft of their left ulna, specifically an oblique break. This particular encounter is for follow-up care of an open fracture (Type I or II) that has healed incorrectly, resulting in a malunion.

This code is appropriate for documenting subsequent visits for a patient with a previously treated open oblique fracture of the left ulnar shaft that has developed a malunion. It would be used when the patient is receiving ongoing management, assessment, or treatment related to this specific complication. This code is not for the initial treatment of the fracture.

• Ensure documentation clearly specifies "left ulna" and "oblique fracture of shaft."
• Verify the original fracture was an "open fracture type I or II" and that "malunion" is explicitly diagnosed.
• Confirm this is a "subsequent encounter" for ongoing care related to the malunion, not the initial injury.
