Nondisp commnt fx l patella, 7thM

This code signifies a comminuted fracture of the left patella that is currently not displaced. It specifically indicates a subsequent encounter for a previously open fracture (Type I or II) that has unfortunately developed nonunion, meaning the bone fragments are failing to heal together.

This code is appropriate when a patient presents for ongoing management of a left patellar fracture that was initially open, but the fracture fragments are now in an acceptable position. It is crucial to use this code when documentation clearly states the presence of nonunion, indicating a failure of the healing process.

• Ensure documentation explicitly states "nondisplaced," "comminuted," and "left patella."
• Verify the original injury was an "open fracture type I or II" and that the current encounter is for follow-up.
• Confirm the presence of "nonunion" in the physician's notes to justify this specific code.
