Unsp disp fx of first cervical vertebra, init for clos fx

This code signifies a fracture of the atlas (C1 vertebra) where the bone fragments are not in their normal anatomical alignment, and the specific type of displacement is not documented. It indicates the patient is receiving initial treatment for a closed fracture, meaning the skin over the fracture site is intact.

Apply this code when documentation confirms a C1 vertebral fracture with displacement, but the specific direction or type of displacement (e.g., anterior, posterior, lateral) is not specified. This is appropriate for the initial encounter for treatment of a newly diagnosed closed fracture. Supporting documentation includes imaging reports (X-ray, CT, MRI) confirming the fracture and displacement, and physician notes detailing the initial treatment.

• Ensure "unspecified displaced" is explicitly or implicitly documented when a more specific displacement type is not available.
• Verify the encounter is for initial treatment; subsequent encounters will require different seventh characters.
• Confirm the fracture is closed; open fractures have distinct coding.
