Oth disp fx of second cervcal vert, subs for fx w routn heal

This code signifies a fracture of the second cervical vertebra (axis) that is not in its normal anatomical alignment, and the patient is in a subsequent phase of care where the fracture is healing as expected. It specifically excludes odontoid fractures and traumatic spondylolisthesis (hangman's fracture).

Apply this code when a patient presents for follow-up care of a previously diagnosed, displaced C2 fracture (excluding odontoid and hangman's) and the provider's documentation indicates routine healing. This code is appropriate for office visits, imaging interpretations, or physical therapy encounters during the healing phase.

• Ensure documentation specifies "displaced" and "other" to differentiate from odontoid or hangman's fractures.
• Verify the encounter is "subsequent" and healing is "routine" (e.g., no complications, delayed healing, or nonunion).
• Always sequence this code after any acute injury codes if the patient is still being treated for the initial trauma.
