Nondisp commnt fx unsp patella, 7thQ

This code describes a patellar fracture that is broken into multiple pieces (comminuted) but remains in its anatomical position (nondisplaced). It specifically applies to an open fracture (where the bone broke through the skin) of Type I or II that is now healing incorrectly, resulting in a malunion. This encounter is for follow-up care of this healing complication.

This code is used when a patient presents for treatment or evaluation of a previously sustained open comminuted patellar fracture (Type I or II) that is now demonstrating signs of malunion. This would typically be documented during a follow-up visit after initial treatment, where imaging confirms the malalignment of the healing bone fragments.

• Ensure documentation clearly specifies "nondisplaced" and "comminuted" for the patellar fracture.
• Verify the original injury was an "open fracture type I or II" and that the current encounter is for a "malunion."
• Confirm this is a "subsequent encounter" for the healing complication, not the initial treatment of the fracture.
