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

This code describes a right patellar fracture that runs lengthwise (longitudinal) and is no longer in its correct anatomical position (displaced). It specifically indicates that the patient is being seen for follow-up care of this fracture, which has healed incorrectly (malunion) and is currently closed (skin intact).

Use this code for a patient presenting for ongoing management or evaluation of a right patellar fracture that has healed with malunion. This applies when the initial injury was a displaced longitudinal fracture and the skin over the fracture site remains unbroken. This code is appropriate for subsequent encounters after the initial treatment phase.

• Ensure documentation clearly specifies "right" patella and "longitudinal" fracture type.
• Verify that the encounter is for a "subsequent" visit and that "malunion" is documented as the healing complication.
• Confirm the fracture is "closed" and not an open fracture with malunion.
