Nondisp apophyseal fx unsp femr, subs for clos fx w nonunion

This code describes a fracture involving the growth plate region of the femur that is not displaced, meaning the bone fragments are still in their normal alignment. Specifically, it indicates that the fracture is not healing as expected (nonunion) and the patient is receiving follow-up care for this closed injury.

Use this code for a patient presenting for ongoing treatment of a previously diagnosed, nondisplaced apophyseal femoral fracture that has failed to unite. This applies when the fracture was initially closed and the current encounter focuses on managing the nonunion.

• Requires a seventh character of 'K' for subsequent encounter with nonunion.
• Ensure documentation clearly states "nondisplaced" and "apophyseal fracture" of the femur.
• Confirm the fracture is closed and the current visit addresses the nonunion complication.
