Displ subtrochnt fx unsp femr, 7thM

This code signifies a subtrochanteric fracture of the femur that is displaced and has failed to heal (nonunion). The fracture was initially an open fracture of type I or II, and the patient is now presenting for follow-up care related to this ongoing healing complication.

This code is used when a patient with a previously diagnosed type I or II open subtrochanteric femur fracture, which was displaced, returns for treatment of a nonunion. This applies to subsequent visits where the primary focus is managing the delayed or failed bone healing.

• Ensure documentation clearly states "nonunion" and specifies the fracture as "displaced subtrochanteric."
• Verify the initial fracture was an open type I or II, as this is a specific inclusion for this code.
• This code is for subsequent encounters; an initial encounter for the fracture would use a different code.
