Displ longitud fx l patella, 7thR

This code signifies a left kneecap fracture that runs lengthwise, where the bone fragments are no longer in their normal alignment. It specifically indicates that the fracture was an open injury, classified as severe (Type IIIA, IIIB, or IIIC), and has healed improperly. This code is used during a follow-up visit after the initial treatment of the fracture.

Use this code for patients presenting for ongoing care or evaluation of a previously treated displaced longitudinal fracture of the left patella. The original injury must have been an open fracture of Gustilo-Anderson type IIIA, IIIB, or IIIC, and the current assessment confirms malunion. This code is appropriate for visits addressing complications or management related to the malunion.

• Ensure documentation clearly specifies "left" patella and "displaced" longitudinal fracture.
• Verify the original injury was an "open fracture" and the specific Gustilo-Anderson type (IIIA, IIIB, or IIIC) is documented.
• Confirm that the current encounter is for a "subsequent encounter" and that "malunion" is the documented complication.
