Displ osteochon fx r patella, subs for clos fx w nonunion

This code signifies a specific type of knee injury involving a displaced osteochondral fracture of the right patella. It indicates that the patient is in a subsequent encounter for this injury, and the fracture, which was initially treated non-surgically (closed), has failed to heal properly (nonunion).

Use this code when documenting follow-up care for a patient with a right patellar osteochondral fracture that was managed non-operatively and has developed a nonunion. This would apply during clinic visits, imaging studies, or other encounters where the ongoing management of the unhealed fracture is the primary focus.

• Ensure documentation clearly specifies "right" patella and "displaced" osteochondral fracture.
• Verify that the encounter is "subsequent" and the fracture was treated "closed" with evidence of "nonunion."
• Do not use for initial encounters or if the fracture has healed or was treated surgically.
