Oth disp fx of first cervical vertebra, init for opn fx

This code signifies a fracture of the atlas (first cervical vertebra) that is not in its normal anatomical alignment, and the skin and/or underlying soft tissue are compromised, exposing the bone. This specific code is used for the initial treatment of such an injury.

Apply this code when a patient presents with a newly diagnosed, displaced C1 fracture that is classified as an open fracture. Documentation should clearly state "open fracture," "displaced," and specify the first cervical vertebra (atlas). This code is appropriate for the initial surgical or non-surgical management of the injury.

• Ensure documentation explicitly states "open fracture" and "displaced" for the first cervical vertebra.
• Verify the encounter type is "initial" for active treatment of the fracture. Subsequent encounters for routine healing or follow-up will require a different 7th character.
• Distinguish from S12.091- series for nondisplaced fractures and S12.000- for unspecified C1 fractures.
