Nondisp subtrochnt fx unsp femr, 7thQ

This code describes a subtrochanteric fracture of the femur that is not displaced, meaning the bone fragments are still in their normal alignment. It specifically indicates that the fracture was initially an open fracture (Type I or II) and has subsequently healed in an abnormal position, resulting in malunion. The affected femur is not specified.

This code is used for follow-up encounters when a patient is being treated for complications of a previously sustained open subtrochanteric femur fracture that has healed with malunion. It applies when the fracture was initially open but is now in a subsequent phase of care, such as rehabilitation or management of the malunion itself.

• Ensure documentation clearly states "nondisplaced," "subtrochanteric fracture," and "malunion."
• Verify the original fracture was documented as an "open fracture type I or II."
• This code is for subsequent encounters, not the initial treatment of the acute fracture.
