Displ transverse fx unsp patella, 7thQ

This code indicates a displaced fracture of the patella's transverse aspect, specifically where the bone has not healed in a normal anatomical alignment (malunion). It specifies an open fracture of Gustilo type I or II, meaning there was a break in the skin communicating with the fracture site, and this encounter is for follow-up care after the initial treatment.

Apply this code for patients presenting for ongoing management of a previously treated open transverse patellar fracture that has developed malunion. This includes follow-up visits for monitoring, planning for corrective surgery, or managing complications related to the malunion. It is appropriate once the initial acute treatment phase is complete and the malunion is identified.

• Ensure documentation clearly specifies "malunion" and not "nonunion" or "delayed union."
• Verify the original fracture was an open transverse patellar fracture, Gustilo type I or II.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture or the malunion.
