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

This code signifies a fracture of the lower portion of the left tibia, excluding the malleoli, that is classified as an open fracture of Gustilo-Anderson type IIIA, IIIB, or IIIC. These open fractures involve significant soft tissue damage, often with extensive contamination and periosteal stripping, and are being treated for the first time.

Use this code for initial encounters when a patient presents with an open fracture of the distal left tibia (excluding ankle fractures) that meets the criteria for Gustilo-Anderson types IIIA, IIIB, or IIIC. This typically involves high-energy trauma with substantial soft tissue injury and bone exposure.

• Ensure the documentation clearly specifies the fracture is of the lower end of the tibia, not an ankle fracture.
• Verify the Gustilo-Anderson classification (IIIA, IIIB, or IIIC) is explicitly documented for open fractures.
• This code is for the initial encounter for treatment; subsequent care will require different encounter codes.
