Displ oblique fx shaft of l ulna, 7thR

This code describes a situation where a patient has a malunion of a previously sustained oblique fracture in the shaft of their left ulna. This specific fracture was an open fracture, classified as type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination. The current encounter is for follow-up care related to this healing complication.

Use this code for patients presenting with a documented malunion of an open oblique fracture of the left ulnar shaft, specifically when the original injury was classified as Gustilo-Anderson type IIIA, IIIB, or IIIC. This code is appropriate for subsequent encounters where the malunion is being addressed or monitored, such as during follow-up appointments, physical therapy, or surgical planning for corrective procedures.

• Ensure documentation clearly specifies "malunion" and the "subsequent encounter" status.
• Verify the original fracture was an "open fracture" and the Gustilo-Anderson classification (IIIA, IIIB, or IIIC) is explicitly stated or clearly inferable.
• Confirm the fracture location is the "shaft of the left ulna" and the fracture type is "oblique."
