Displ osteochon fx r patella, 7thN

This code signifies a complex injury involving a displaced osteochondral fracture of the right kneecap, specifically when the patient is receiving follow-up care for a severe open fracture (Type IIIA, IIIB, or IIIC) that has failed to heal properly (nonunion). An osteochondral fracture affects both the bone and the overlying cartilage.

This code is appropriate for subsequent encounters when a patient with a previously diagnosed severe open right patellar fracture is being treated for nonunion of a displaced osteochondral component. This includes ongoing management, surgical planning for revision, or monitoring of the nonunion.

• Ensure documentation clearly specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC).
• Verify that the encounter is for subsequent care, not the initial treatment of the fracture.
• Confirm the fracture is of the right patella and is displaced and osteochondral.
