Unsp fx lower end of left femur, init for opn fx type I/2

This code signifies an open fracture of the distal portion of the left femur, where the specific type of fracture (e.g., supracondylar, condylar) is not documented. The "open" nature indicates a break in the skin communicating with the fracture, classified as either Type I (minimal skin damage) or Type II (moderate skin damage) according to the Gustilo-Anderson classification. This code is used for the initial treatment of the injury.

Apply this code when a patient presents with a newly diagnosed open fracture of the lower end of the left femur, and the medical record specifies it as Gustilo-Anderson Type I or II, but lacks further detail on the exact fracture pattern. This is appropriate for the initial encounter where definitive treatment is being provided.

• Ensure the documentation clearly states "open fracture" and specifies Type I or II Gustilo-Anderson classification.
• Verify that the fracture is located at the "lower end" or "distal" femur; avoid using for shaft or proximal femur fractures.
• Confirm this is the patient's initial encounter for this specific injury; subsequent care will require different encounter codes.
