Nondisp oblique fx shaft of l ulna, 7thR

This code describes a situation where a patient has a non-displaced oblique fracture in the shaft of their left ulna that is currently healing poorly (malunion). This specific fracture was initially an open fracture of a severe type (IIIA, IIIB, or IIIC), indicating significant soft tissue damage and potential contamination at the time of injury. The current encounter is for ongoing management of this complicated healing process.

Apply this code when documenting a patient's follow-up visit for a previously sustained open oblique fracture of the left ulnar shaft that is now demonstrating malunion. This is appropriate for encounters where the physician is assessing the malunion, planning corrective procedures, or managing complications related to the poor healing.

• Ensure documentation clearly specifies "malunion" and the "subsequent encounter" status.
• Verify the original injury was an "open fracture type IIIA, IIIB, or IIIC" of the left ulna shaft.
• Do not use for initial treatment of the fracture or for nonunion; a different code would apply for those scenarios.
