Type III traum spondylolysis of sixth cervcal vert, sequela

This code signifies a chronic or late effect of a traumatic anterior displacement of the C6 vertebral body relative to C7, specifically a Type III spondylolisthesis. This type involves a bilateral pedicle fracture, leading to instability. The "sequela" designation indicates that the injury itself has healed, but residual symptoms or complications persist.

Apply this code when documenting long-term neurological deficits, chronic pain, instability, or other persistent issues directly attributable to a previously sustained Type III traumatic C6 spondylolisthesis. Documentation should clearly state the C6 level, the Type III classification, and the ongoing nature of the condition as a sequela of the original trauma.

• Ensure documentation specifies "Type III" spondylolisthesis and the C6 vertebral level; otherwise, a more general code may be appropriate.
• The "S" seventh character indicates sequela, meaning this code is used for complications or conditions arising after the initial injury has healed.
• Always sequence this code after the primary diagnosis describing the specific sequela (e.g., chronic pain, radiculopathy).
