Oth fx upper end of left tibia, init for opn fx type 3A/B/C

This code signifies a fracture of the proximal (upper) portion of the left tibia, excluding the specific types of fractures (e.g., Salter-Harris, avulsion) that have their own distinct codes. It specifies an open fracture, meaning the bone has broken through the skin, and further classifies it as a severe open fracture (Gustilo-Anderson type IIIA, IIIB, or IIIC) indicating significant soft tissue damage and contamination. This is the initial encounter for treatment of this injury.

Apply this code when documenting the initial treatment of a patient presenting with a severe open fracture of the upper left tibia, where the fracture pattern is not otherwise specified. This includes cases involving extensive soft tissue injury, periosteal stripping, or significant contamination. It is appropriate for the first visit where definitive treatment or management of the fracture begins.

• Ensure documentation clearly specifies "left" tibia and "upper end" or "proximal" to differentiate from other tibial fractures.
• Verify the Gustilo-Anderson classification (IIIA, IIIB, or IIIC) is explicitly stated or clearly inferable from the clinical notes for an open fracture.
• Confirm this is the "initial encounter" for the fracture; subsequent care would use a different seventh character.
