Anterior displaced Type II dens fracture, init for clos fx

This code signifies a fracture of the odontoid process (dens) of the C2 vertebra, specifically a Type II fracture where the anterior fragment is displaced. This injury involves the neck of the dens and is considered unstable due to its location and potential for non-union. The "initial encounter" indicates the patient is receiving active treatment for the fracture.

Use this code for patients presenting with a newly diagnosed, anteriorly displaced Type II dens fracture, prior to definitive treatment or during the acute phase of care. Documentation should clearly state "Type II dens fracture," "anterior displacement," and confirm it's a closed fracture (skin intact). This code is appropriate for initial evaluations, surgical planning, or initial conservative management.

• Always verify the fracture type (I, II, or III) and displacement direction (anterior, posterior, or nondisplaced) from imaging reports and physician documentation.
• Distinguish between initial, subsequent, and sequela encounters based on the patient's treatment phase.
• Ensure documentation specifies "closed fracture" to avoid using codes for open fractures.
