Oth fx lower end of unsp femur, init for opn fx type 3A/B/C

This code signifies a fracture of the lower portion of the femur, not otherwise specified as to the exact location within the lower end, that is an open fracture classified as Type IIIA, IIIB, or IIIC according to the Gustilo-Anderson classification. This indicates significant soft tissue damage and a high risk of infection, and it is the initial treatment encounter for this injury.

Use this code for a patient presenting for the first time with an open fracture of the distal femur where the specific anatomical site (e.g., condyle, epicondyle) is not documented, but the Gustilo-Anderson classification clearly indicates a Type IIIA, IIIB, or IIIC open injury. This code is appropriate for the initial surgical repair or management of such a severe open fracture.

• Ensure documentation explicitly states "initial encounter" and specifies the Gustilo-Anderson open fracture type (IIIA, IIIB, or IIIC).
• If the specific anatomical site of the lower femoral fracture is documented (e.g., medial condyle), a more specific code should be selected.
• Do not use this code for subsequent encounters or for open fractures classified as Type I or Type II.
