Nondisp commnt fx left patella, subs for clos fx w malunion

This code signifies a left kneecap fracture that has broken into multiple pieces but remains in its anatomical position, with the patient now in a subsequent phase of care. A key feature is the presence of malunion, indicating the fracture has healed, but in an imperfect or misaligned position.

Apply this code for follow-up encounters where a patient is being managed for a previously diagnosed comminuted, nondisplaced fracture of the left patella. It is specifically used when documentation confirms that the fracture has healed with malunion, and the treatment for this closed fracture is ongoing.

• Ensure documentation explicitly states "nondisplaced," "comminuted," and "left patella."
• Verify the encounter is for subsequent care and that "malunion" is present and being addressed.
• Do not use for initial encounters or if the fracture is still open or has not yet healed.
