Nondisp commnt fx r patella, 7thR

This code describes a comminuted fracture of the right kneecap that is not displaced, meaning the bone fragments are still in their normal alignment. It specifically indicates a subsequent encounter for an open fracture (where the bone broke through the skin) classified as type IIIA, IIIB, or IIIC, which has healed incorrectly, resulting in malunion.

Use this code for follow-up visits or ongoing treatment of a patient who previously sustained a severe open comminuted fracture of the right patella. This code is appropriate when documentation confirms the fracture is now nondisplaced but has healed with a deformity or misalignment (malunion).

• Ensure documentation clearly specifies "nondisplaced" and "comminuted" for the patellar fracture.
• Verify that the original injury was an open fracture of type IIIA, IIIB, or IIIC and that malunion is present.
• This code is for subsequent encounters; an initial encounter would use a different code.
