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

This code signifies a fracture located between the greater and lesser trochanters of the femur that has not shifted from its original position. It specifically indicates that the patient is in a subsequent phase of care for this closed fracture, and a nonunion of the bone fragments has been identified.

This code is appropriate for follow-up encounters where a previously diagnosed nondisplaced intertrochanteric femoral fracture, which was initially closed, is now complicated by a documented nonunion. This would typically be used when the patient is receiving ongoing treatment or evaluation for the failed healing of the fracture.

• Ensure documentation clearly states "nondisplaced" and "intertrochanteric" for the fracture type.
• Verify that the encounter is for subsequent care and that a nonunion of the closed fracture is explicitly documented.
• Do not use this code for initial fracture treatment or for malunion, which is a different complication.
