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

This code signifies an open fracture of the distal right 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 a severe type IIIA, IIIB, or IIIC Gustilo-Anderson classification, and represents the initial treatment encounter.

This code is appropriate for the initial hospital admission or outpatient visit for a patient presenting with a severe open fracture of the lower end of the right femur, where the precise anatomical location of the fracture within the distal femur is not specified in the medical record. It is used when the Gustilo-Anderson classification for an open fracture is documented as IIIA, IIIB, or IIIC.

• Ensure documentation clearly states "right femur" and "lower end" or "distal femur."
• Verify the Gustilo-Anderson classification is explicitly documented as IIIA, IIIB, or IIIC for the open fracture.
• This code is only for the initial encounter; subsequent encounters will require a different seventh character.
