Bent bone of left ulna, init for opn fx type 3A/B/C

This code signifies a fracture of the left ulna where the bone is bent or angulated, and the fracture site has an open wound communicating with the outside environment. This specific code is used for severe open fractures classified as Type IIIA, IIIB, or IIIC according to the Gustilo-Anderson classification, indicating significant soft tissue damage.

Apply this code when documenting the initial treatment for a patient presenting with an open, angulated fracture of the left ulna resulting from high-energy trauma, such as a motor vehicle accident or a fall from a significant height. This code is appropriate for the initial hospital admission or emergency department visit where definitive treatment for the fracture is initiated.

• Ensure documentation clearly specifies "left ulna" and "bent bone" or "angulated fracture."
• Verify the Gustilo-Anderson classification (Type IIIA, IIIB, or IIIC) is explicitly stated in the physician's notes.
• Confirm this is the patient's initial encounter for this specific fracture. Subsequent care would use a different encounter character.
