Oth fx upper end of right ulna, init for opn fx type 3A/B/C

This code signifies a fracture in the upper portion of the right ulna that is not further specified as a Monteggia fracture or other specific type. It indicates an open fracture, meaning the skin and soft tissues were significantly damaged, exposing the bone, and is classified as a severe open fracture (Gustilo-Anderson type IIIA, IIIB, or IIIC). This is the initial encounter for treatment of this injury.

Use this code for a patient presenting for the first time with a severe open fracture of the proximal right ulna, where the specific fracture pattern (e.g., olecranon, coronoid) is not documented or is described as "other." This applies to injuries involving significant soft tissue damage and bone exposure requiring initial surgical intervention or definitive treatment.

• Ensure documentation clearly specifies "right" ulna and "upper end" or "proximal."
• Verify the Gustilo-Anderson classification (IIIA, IIIB, or IIIC) for open fractures is explicitly stated.
• Confirm this is the patient's initial encounter for this specific injury. Subsequent care would require a different encounter character.
