Displ osteochon fx unsp patella, subs for clos fx w malunion

This code describes a displaced fracture involving both the bone and cartilage of the kneecap, where the fracture has healed in an abnormal position (malunion). This specific code is used when the patient is receiving follow-up care for this previously treated fracture.

Use this code for patients presenting for ongoing management, physical therapy, or evaluation of complications related to a malunited osteochondral fracture of an unspecified patella. This applies when the initial fracture treatment has concluded, and the patient is now in the healing phase with a documented malunion.

• Ensure documentation specifies "subsequent encounter" and "malunion" for this code to be appropriate.
• The "unspecified patella" indicates that the laterality (left or right) of the patella is not documented.
• This code is for a closed fracture, meaning the skin was intact over the fracture site.
