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

This code signifies a fracture of the upper portion of the tibia (shin bone) that is not otherwise specified, meaning the exact location within the upper end is not detailed. It specifically indicates an open fracture, where the bone has broken through the skin, and is classified as a severe open fracture type IIIA, IIIB, or IIIC according to the Gustilo-Anderson classification. This is the initial encounter for treatment of this injury.

This code is appropriate for documenting the initial treatment of a patient presenting with a severe open fracture of the proximal tibia where the specific anatomical site (e.g., tibial plateau, tibial tuberosity) is not documented. It is used when the open nature of the fracture is classified as Gustilo-Anderson type IIIA, IIIB, or IIIC, indicating significant soft tissue damage.

• Ensure documentation explicitly states "initial encounter" for this specific injury.
• Verify that the fracture is indeed open and classified as Gustilo-Anderson type IIIA, IIIB, or IIIC.
• If a more specific location of the fracture in the upper tibia is documented (e.g., tibial plateau), a more precise code should be used.
