Nondisp longitud fx r patella, subs for clos fx w malunion

This code signifies a right kneecap fracture that runs lengthwise (longitudinal) and has not shifted out of alignment. The patient is in a later stage of care, and the fracture has healed improperly, resulting in a malunion, but the skin over the fracture remains intact.

Apply this code when documenting follow-up care for a patient with a previously diagnosed nondisplaced longitudinal fracture of the right patella that has developed a malunion. This would include scenarios where the patient is undergoing rehabilitation, further imaging, or considering corrective surgery for the malunion, and the fracture is not an open wound.

• Ensure documentation clearly states "right patella," "longitudinal," "nondisplaced," and "malunion" for accurate code assignment.
• The "P" seventh character indicates a subsequent encounter for a closed fracture with malunion; verify the encounter type.
• Do not use this code for initial treatment or for fractures that are still in the process of normal healing.
