Displ transverse fx r patella, 7thQ

This code signifies a displaced fracture of the right patella, specifically involving the transverse portion, that is currently undergoing treatment for a malunion. The initial injury was an open fracture, classified as Type I or II, indicating a less severe open wound.

This code is appropriate for subsequent encounters when a patient is receiving care for a malunion of a previously treated displaced transverse open fracture (Type I or II) of the right patella. This includes follow-up visits, cast changes, or other ongoing management related to the healing complication.

• Ensure documentation clearly specifies "malunion" as the reason for the subsequent encounter.
• Verify the laterality (right patella) and the specific fracture type (transverse, displaced, open Type I or II).
• Do not use this code for initial treatment or for nonunion; specific codes exist for those scenarios.
