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

This code signifies a fracture of the distal (lower) portion of the femur, where the specific location or type of fracture within the lower end is not documented. It indicates an open fracture with significant soft tissue damage, categorized as Gustilo-Anderson Type IIIA, IIIB, or IIIC, and represents the initial treatment encounter for this injury.

Use this code when documentation clearly states an open fracture of the lower end of the femur, but lacks specificity regarding the exact fracture pattern (e.g., supracondylar, intercondylar, condylar). It is appropriate for the initial hospitalization or treatment encounter for severe open fractures with extensive soft tissue injury, periosteal stripping, or arterial damage.

• Always strive for greater specificity if available in the medical record (e.g., supracondylar, condylar).
• Ensure the documentation explicitly states "open fracture type IIIA, IIIB, or IIIC" and that it is the "initial encounter."
• Do not use this code if the fracture is closed or if the encounter is for subsequent care.
