Displ osteochon fx unsp patella, 7thQ

This code describes a specific type of knee injury involving a displaced fracture of both bone and cartilage within the kneecap, where the initial injury was an open fracture (Type I or II). The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and "malunion" signifies that the fracture has healed, but in an unsatisfactory or misaligned position.

This code is used when a patient presents for ongoing treatment or evaluation of a patellar osteochondral fracture that was initially an open fracture (Type I or II) and has now healed with malunion. This would typically apply during rehabilitation, follow-up appointments after initial surgical repair, or when assessing the functional impact of the malunion.

• Ensure documentation clearly specifies a displaced osteochondral fracture of the patella and confirms an initial open fracture (Type I or II).
• Verify that the encounter is for follow-up care and that malunion of the fracture is explicitly documented.
• Do not use this code for initial encounters, nonunion, or routine healing without malunion.
