Displ osteochon fx unsp patella, 7thJ

This code describes a specific type of patellar fracture where a piece of bone and cartilage has broken off and is no longer in its correct anatomical position. It indicates that the fracture was initially an open fracture (meaning the skin was broken) of a severe type (IIIA, IIIB, or IIIC) and is now experiencing delayed healing during a subsequent encounter.

Use this code for a patient presenting for follow-up care of a previously diagnosed displaced osteochondral fracture of an unspecified patella, where the initial injury was a severe open fracture. This code is appropriate when the physician explicitly documents delayed healing of this specific fracture type.

• Ensure documentation specifies "displaced osteochondral fracture" and "delayed healing" for the unspecified patella.
• Verify the original injury was an open fracture type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters, not the initial treatment of the fracture.
