Type I occipital condyle fracture, left side, init

This code signifies a fracture of the left occipital condyle, which is the bony prominence at the base of the skull that articulates with the first cervical vertebra (atlas). A Type I fracture indicates an impaction fracture without significant displacement, typically stable. This diagnosis is for the initial treatment phase of the injury.

Apply this code when documentation confirms a non-displaced, stable fracture of the left occipital condyle, as classified by the Anderson and Montesano system. This is appropriate for the first encounter where the fracture is diagnosed and treatment is initiated, such as in an emergency department or initial orthopedic consultation. Imaging reports (e.g., CT scan) confirming the fracture type and location are essential.

• Ensure the documentation specifies "Type I" and "left side" to accurately use this code.
• Verify the encounter is indeed the "initial encounter" for this specific fracture; subsequent care would use a different encounter character.
• Distinguish from other occipital condyle fracture types (Type II, Type III) and bilateral involvement, which have distinct codes.
