Displ longitud fx unsp patella, 7thN

This code describes a patellar fracture that runs lengthwise, where the bone fragments are no longer in their normal alignment. It specifically indicates an open fracture (meaning the skin was broken) that was severe (Type IIIA, IIIB, or IIIC) and has failed to heal properly, resulting in a nonunion. This is a subsequent encounter, meaning the patient is receiving follow-up care for this previously treated injury.

Use this code for a patient presenting for ongoing management of a displaced longitudinal patellar fracture that was initially an open fracture (Type IIIA, IIIB, or IIIC) and has now developed a nonunion. This code is appropriate for follow-up visits, surgical interventions for nonunion, or other treatments related to the failed healing of this specific fracture type.

• Ensure documentation clearly specifies a displaced longitudinal patellar fracture and an open fracture type IIIA, IIIB, or IIIC.
• Verify that the encounter is for subsequent care and not the initial treatment of the fracture.
• Confirm that the diagnosis explicitly states nonunion as the reason for the ongoing care.
