Displ subtrochnt fx unsp femur, init for opn fx type 3A/B/C

This code signifies a fracture located below the lesser trochanter of the femur, where the bone fragments are no longer in their normal alignment. It specifically applies to open fractures, meaning the skin and soft tissues have been significantly damaged, exposing the bone, and are classified as Gustilo-Anderson type IIIA, IIIB, or IIIC. This code is used for the initial treatment of such an injury.

This code is appropriate for documenting the initial encounter for a patient presenting with a subtrochanteric femur fracture that is visibly displaced and involves a severe open wound. This includes cases where there is extensive soft tissue damage, periosteal stripping, or arterial injury requiring repair, as defined by the Gustilo-Anderson classification for open fractures.

• Ensure documentation clearly specifies "displaced" and identifies the fracture as subtrochanteric.
• Verify the Gustilo-Anderson classification (IIIA, IIIB, or IIIC) is explicitly stated by the provider for the open fracture.
• This code is only for the initial encounter for treatment of the fracture. Subsequent care will require different encounter codes.
