Oth traum displ spondylolysis of sixth cervcal vert, sequela

This code signifies a long-term complication or late effect resulting from a traumatic displacement of the sixth cervical vertebra (C6) where one vertebral body has slipped forward or backward relative to the one below it. This spondylolisthesis is not specified as a fracture, dislocation, or subluxation, but rather an "other" type of traumatic displacement. The "S" suffix indicates that this is a sequela, meaning the initial injury has healed, but residual effects persist.

Use this code when documenting a patient presenting with ongoing symptoms or conditions directly attributable to a past traumatic spondylolisthesis of the C6 vertebra. This applies when the acute phase of the injury has passed, and the current encounter addresses the chronic consequences. Documentation should clearly state a history of traumatic C6 spondylolisthesis and the current condition being a sequela.

• Ensure documentation explicitly links the current condition to a past traumatic C6 spondylolisthesis.
• Do not use for acute or initial encounters of the injury; those would utilize codes without the "S" suffix.
• Distinguish from non-traumatic spondylolisthesis (e.g., degenerative) which would be coded from the M43 category.
