Displ osteochon fx l patella, 7thQ

This code describes a specific type of knee injury involving a displaced fracture of both bone and cartilage in the left kneecap, which was initially an open fracture (skin broken) of Type I or II severity. The "subsequent encounter" indicates that the patient is receiving follow-up care for this injury, and "malunion" signifies that the fracture has healed in an incorrect or deformed position.

Use this code for patients presenting for ongoing treatment, rehabilitation, or evaluation of complications related to a previously sustained open osteochondral fracture of the left patella that has healed poorly. This applies when the initial injury was an open fracture of Gustilo-Anderson Type I or II, and the current clinical assessment confirms malunion.

• Ensure documentation clearly specifies "left" patella and "displaced" osteochondral fracture.
• Verify that the original injury was an "open fracture type I or II" and that "malunion" is explicitly documented.
• This code is for subsequent encounters; an initial encounter would use a different code from the S82.012- series.
