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

This code signifies a fracture of the lower end of the tibia that is not further specified as to its exact location, and is an open fracture classified as Type IIIA, IIIB, or IIIC according to the Gustilo-Anderson classification. This indicates significant soft tissue damage and contamination, requiring immediate surgical intervention.

Use this code for the initial treatment of a patient presenting with an open fracture of the distal tibia where the specific location (e.g., medial malleolus, pilon) is not documented, and the wound is severe enough to be classified as Gustilo-Anderson Type IIIA, IIIB, or IIIC. This code is appropriate for the first encounter for this specific injury.

• Ensure documentation clearly states an "open fracture" and specifies the Gustilo-Anderson type (IIIA, IIIB, or IIIC).
• This code is for the "initial encounter" only; subsequent care would require a different encounter character.
• If the specific location of the fracture at the lower end of the tibia is known, a more specific code should be used.
