Nondisp apophyseal fx unsp femr, 7thN

This code describes a situation where a patient is being treated for a previously sustained, non-displaced fracture of a growth plate (apophysis) in an unspecified femur. The fracture was initially an open fracture, classified as type IIIA, IIIB, or IIIC, and has now failed to heal properly, resulting in a nonunion.

Use this code for follow-up encounters where a patient presents with a documented nonunion of a non-displaced apophyseal fracture of the femur. This applies when the initial injury was an open fracture of Gustilo-Anderson type IIIA, IIIB, or IIIC, and the current visit addresses the ongoing nonunion.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" status.
• Verify the original fracture was an "open fracture" and the Gustilo-Anderson classification (IIIA, IIIB, or IIIC) is present in the patient's history.
• Do not use for initial encounters or for fractures that are healing normally.
