Nondisp longitud fx r patella, 7thN

This code describes a situation where a patient has a non-displaced fracture running lengthwise through the right kneecap, and the fracture has failed to heal properly (nonunion). This specific encounter involves an open fracture that was initially classified as a severe type (IIIA, IIIB, or IIIC) according to the Gustilo-Anderson classification.

Use this code for follow-up encounters where a patient is receiving ongoing treatment or evaluation for a previously diagnosed nondisplaced longitudinal fracture of the right patella that has developed nonunion. This applies when the initial injury was an open fracture of Gustilo type IIIA, IIIB, or IIIC, and the nonunion is the focus of the current visit.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" status for the fracture.
• Verify the laterality (right) and the specific fracture type (nondisplaced longitudinal patella).
• Confirm the original open fracture was classified as Gustilo type IIIA, IIIB, or IIIC.
