Unsp fx upr end l ulna, 7thJ

This code signifies an unspecified fracture of the upper portion of the left ulna that was initially an open fracture of severe type (IIIA, IIIB, or IIIC). The patient is currently in a subsequent phase of care, and the fracture is experiencing delayed healing.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed severe open fracture of the proximal left ulna is being treated for delayed union or nonunion. This applies when the specific type of fracture (e.g., olecranon, coronoid) was not documented at the initial encounter.

• Ensure documentation clearly states "delayed healing" for this subsequent encounter.
• Verify the initial fracture was indeed an open fracture classified as type IIIA, IIIB, or IIIC.
• Confirm the fracture location is the upper end of the left ulna and the specific type of fracture is not further specified.
