Displ commnt fx r patella, 7thR

This code describes a complex fracture of the right kneecap where the bone has broken into multiple pieces and is no longer properly aligned. It specifically indicates a severe open fracture (Type IIIA, IIIB, or IIIC), meaning the bone has broken through the skin, and the fracture has healed incorrectly, resulting in a malunion.

Use this code for a patient presenting for follow-up care or treatment of a previously sustained, severely comminuted and displaced open right patellar fracture that has healed in an unsatisfactory position. This applies when the initial injury was an open fracture of Gustilo-Anderson Type IIIA, IIIB, or IIIC, and the current encounter addresses complications arising from the malunion.

• Ensure documentation clearly specifies "malunion" and the Gustilo-Anderson open fracture type (IIIA, IIIB, or IIIC) from the initial injury.
• This is a "subsequent encounter" code, so it should be used after the initial treatment phase for the acute fracture.
• Verify laterality (right patella) is explicitly stated in the medical record.
