Displ longitud fx l patella, 7thN

This code signifies a fracture of the left kneecap that runs lengthwise, where the bone fragments are no longer in their normal alignment. It specifically indicates that the patient is receiving follow-up care for a severe open fracture (Type IIIA, IIIB, or IIIC) that has failed to heal properly.

Apply this code when documenting subsequent treatment for a patient with a previously diagnosed displaced longitudinal fracture of the left patella. This is appropriate when the initial injury was a severe open fracture and the current encounter addresses the ongoing nonunion of that fracture.

• Ensure documentation clearly specifies "left" patella and "longitudinal" fracture type.
• Verify the original injury was classified as an open fracture type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters addressing the nonunion, not the initial treatment of the fracture.
