Oth traum nondisp spondylolysis of second cervcal vert, init

This code describes a fracture involving the second cervical vertebra (C2) that results in a traumatic spondylolisthesis, meaning one vertebral body has slipped forward relative to the one below it, but without significant displacement. This specific code indicates the injury is a closed fracture, meaning the skin remains intact, and it is the initial encounter for treatment.

Use this code for patients presenting with a newly diagnosed, non-displaced traumatic spondylolisthesis of the C2 vertebra, where the fracture is closed. Documentation should clearly state "traumatic spondylolisthesis," specify the C2 level, confirm "nondisplaced," and indicate "closed fracture" in the diagnostic statement. This code is appropriate for the period of active treatment for the fracture.

• Ensure documentation specifies "nondisplaced" to differentiate from displaced spondylolisthesis codes.
• Verify the encounter type is "initial" for active treatment; subsequent encounters will require different seventh characters.
• Distinguish traumatic spondylolisthesis from degenerative or congenital forms, which are coded differently.
