Oth traum displ spondylolysis of 2nd cervcal vert, 7thD

This code signifies a follow-up encounter for a fracture involving the second cervical vertebra (C2) where a traumatic spondylolisthesis (forward displacement of one vertebra over another) is present and displaced, but the fracture is healing routinely. It specifically excludes hangman's fractures.

Apply this code for patients presenting for routine follow-up care of a C2 traumatic spondylolisthesis that was initially displaced, and the fracture is progressing as expected without complications. Documentation should clearly indicate "subsequent encounter," "routine healing," and specify the C2 level and traumatic origin of the spondylolisthesis.

• Ensure documentation specifies "displaced" and "traumatic" to differentiate from non-displaced or congenital forms.
• Verify the encounter type is "subsequent" and healing is "routine"; different seventh characters apply for initial encounters or delayed/nonunion healing.
• Do not use this code for hangman's fractures; a more specific code exists for that condition.
