Unsp trochan fx unsp femur, init for opn fx type 3A/B/C

This code signifies a fracture of the trochanteric region of the femur, where the specific type of trochanteric fracture (e.g., intertrochanteric, subtrochanteric) is not documented. It is an open fracture, meaning the bone has broken through the skin, and is classified as a severe open fracture (Gustilo-Anderson type IIIA, IIIB, or IIIC) indicating significant soft tissue damage and contamination. This code is used for the initial treatment of the injury.

This code is appropriate when documentation clearly indicates an open trochanteric fracture of the femur, but lacks specificity regarding the exact trochanteric location. It is specifically for cases where the Gustilo-Anderson classification is documented as IIIA, IIIB, or IIIC, and the patient is receiving initial active treatment for the fracture.

• Ensure the documentation explicitly states "open fracture" and specifies Gustilo-Anderson type IIIA, IIIB, or IIIC.
• Only use this code for the initial encounter for treatment of the fracture; subsequent encounters will require a different seventh character.
• If the specific trochanteric location (e.g., intertrochanteric, subtrochanteric) is documented, a more specific code should be used.
