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

This code signifies a fracture of the distal end of the left femur, excluding condylar or supracondylar fractures, that has broken through the skin. The open nature of the fracture is classified as Gustilo-Anderson type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and potential contamination. This code is used for the initial treatment of such an injury.

Use this code for a patient presenting with a newly diagnosed, non-specific fracture of the lower left femur that is openly exposed to the environment. This applies when the orthopedic surgeon documents an open fracture classified as type IIIA, IIIB, or IIIC, and the patient is receiving their initial care for this injury.

• Ensure the documentation clearly specifies "left" femur and "lower end" (distal) but not specifically condylar or supracondylar.
• Verify the Gustilo-Anderson classification (IIIA, IIIB, or IIIC) is explicitly stated by the physician.
• Confirm this is the patient's first encounter for treatment of this specific fracture.
