Displ osteochon fx r patella, 7thM

This code describes a specific type of knee injury involving a displaced fracture of both bone and cartilage on the right kneecap. It indicates that the fracture was initially an open fracture (meaning the skin was broken) of either Type I or II, and that the bone fragments have failed to heal together properly (nonunion) during a follow-up visit.

Use this code for a patient presenting for ongoing management of a previously sustained open osteochondral fracture of the right patella, where imaging or clinical assessment confirms that the fracture has not united. This applies to follow-up appointments, cast changes, or surgical planning for the nonunion.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" status.
• Verify the original open fracture type (I or II) is documented or can be inferred from the patient's history.
• Confirm the laterality (right patella) is explicitly stated in the medical record.
