Displ spiral fx shaft of ulna, l arm, 7thR

This code signifies a left ulnar shaft fracture that is displaced and has a spiral pattern, indicating a rotational force injury. It specifically describes a subsequent encounter for an open fracture (Type IIIA, IIIB, or IIIC) that has healed improperly, resulting in malunion.

Use this code when documenting follow-up care for a patient with a previously treated open spiral fracture of the left ulnar shaft that has healed in an anatomically incorrect position. This applies to situations where the initial open fracture was severe (Type IIIA, IIIB, or IIIC) and the current encounter addresses the complications of malunion.

• Ensure documentation clearly specifies "subsequent encounter" and the presence of malunion.
• Verify the laterality (left arm) and the specific fracture type (spiral, displaced, shaft of ulna).
• Confirm the original open fracture was classified as Type IIIA, IIIB, or IIIC.
