Displ commnt fx r patella, 7thM

This code signifies a complex fracture of the right kneecap where the bone has broken into multiple pieces and the fragments are not in their normal anatomical alignment. It specifically indicates that this is a follow-up encounter for an open fracture (meaning the skin was broken) of either Type I or II, and the fracture has failed to heal properly.

Apply this code for patients presenting for ongoing management of a previously sustained open comminuted fracture of the right patella that has not achieved bony union. This would include scenarios such as follow-up appointments for non-operative management of nonunion, or pre-operative assessment for surgical intervention to address the nonunion. It is crucial that the initial injury was an open fracture of Type I or II.

• Ensure documentation clearly specifies "nonunion" and that the encounter is "subsequent."
• Verify the laterality (right patella) and the comminuted nature of the fracture.
• Confirm the original injury was an open fracture, specifically Type I or II, as documented in the patient's history.
