Displ transverse fx l patella, 7thN

This code signifies a non-healing fracture of the left kneecap, specifically a transverse break that is no longer in proper alignment. It indicates that the initial injury was an open fracture, classified as severe (Type IIIA, IIIB, or IIIC), and the patient is now being seen for ongoing management of the fracture's failure to unite.

Apply this code when a patient presents for follow-up care, surgical intervention, or other treatment related to a previously diagnosed displaced transverse fracture of the left patella. The key is that the initial fracture was open and severe, and the current encounter addresses the complication of nonunion. This would include scenarios like planning for revision surgery or managing complications of the nonunion.

• Ensure documentation clearly specifies "nonunion" and the "displaced" nature of the transverse patellar fracture.
• Verify the initial fracture was indeed an "open fracture type IIIA, IIIB, or IIIC" as this is a critical component of the code.
• This is a subsequent encounter code; do not use for the initial treatment of the fracture.
