Displ osteochon fx unsp patella, 7thN

This code signifies a displaced fracture involving both bone and cartilage of the kneecap, where the initial injury was an open fracture of severe type (IIIA, IIIB, or IIIC). The patient is currently receiving care for a complication where the fracture fragments have failed to heal properly.

Apply this code for follow-up encounters when a patient with a previously diagnosed severe open osteochondral patellar fracture is being treated for nonunion. This indicates ongoing management for the failure of the fracture to mend.

• Ensure documentation specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC) for accurate code assignment.
• Verify the encounter is for subsequent care, not the initial treatment of the fracture.
• Confirm the fracture is explicitly described as "displaced" and involves the osteochondral portion of the patella.
