Displ commnt fx right patella, subs for clos fx w malunion

This code describes a complex fracture of the right kneecap where the bone has broken into multiple pieces and the fragments are not in their normal anatomical alignment. This specific code indicates that the patient is receiving follow-up care for this fracture, and the bone has healed in an imperfect position, leading to a malunion.

Use this code for a patient presenting for ongoing treatment, evaluation, or management of a previously sustained displaced comminuted fracture of the right patella. The key clinical finding for this specific code is documentation of malunion, meaning the fracture has healed but with an unacceptable alignment or deformity. This would typically be used after initial treatment and during the rehabilitation or long-term follow-up phase.

• Ensure documentation clearly specifies "right" patella and "displaced comminuted" fracture.
• The "P" seventh character is crucial, indicating a subsequent encounter for a closed fracture with malunion.
• Verify that the physician's notes explicitly state or imply a malunion, not just delayed healing or nonunion.
