Unsp trochan fx r femur, subs for opn fx type I/2 w nonunion

This code signifies a right femur fracture involving the trochanteric region, where the specific type of trochanteric fracture is not documented. It indicates that the initial injury was an open fracture (Type I or II) and the bone has failed to heal properly, requiring ongoing medical attention.

This code is appropriate for follow-up encounters for patients with a previously diagnosed, unspecified open trochanteric fracture of the right femur that has progressed to nonunion. It should be used when the patient is receiving active treatment for the nonunion, such as surgical intervention, bone grafting, or prolonged immobilization.

• Ensure documentation clearly states "nonunion" and specifies the right femur.
• Verify the initial fracture was documented as an open fracture, Type I or II.
• Do not use for initial encounters or for fractures that have healed or are in routine follow-up for healing.
