Displ oblique fx shaft of l ulna, 7thK

This code signifies a specific type of fracture in the shaft of the left ulna, where the break is angled (oblique) and the bone fragments are not properly aligned (displaced). The "nonunion" aspect indicates that the fracture has failed to heal completely after a previous attempt at treatment.

This code is appropriate for encounters where a patient is being treated for a previously diagnosed displaced oblique fracture of the left ulnar shaft that has not healed. This includes follow-up visits for ongoing management, evaluation of nonunion, or preparation for further intervention (e.g., surgery, bone grafting) to address the nonunion.

• Ensure documentation clearly specifies "nonunion" for this subsequent encounter.
• Verify the fracture is of the shaft of the ulna and is displaced and oblique.
• Confirm the laterality is left and that this is not the initial encounter for the fracture.
