Oth traum displ spondylolysis of sixth cervcal vert, 7thG

This code signifies a forward slippage of the sixth cervical vertebra (C6) over the vertebra below it, resulting from a traumatic injury. The displacement is not due to a congenital defect or degenerative process. This specific code is used when the patient is seen for follow-up care of this fracture, and the healing process is progressing slower than expected.

Apply this code for a patient presenting for ongoing management of a previously diagnosed traumatic spondylolisthesis of C6, where the fracture component is exhibiting delayed union or nonunion. Documentation should clearly indicate the traumatic etiology of the spondylolisthesis and the delayed healing status of the associated fracture. This code is appropriate for subsequent encounters after the initial treatment.

• Ensure documentation specifies "traumatic" origin and "displaced" nature of the spondylolisthesis.
• Verify the encounter is for "subsequent" care and explicitly states "delayed healing" of the fracture.
• Distinguish from non-traumatic spondylolisthesis (e.g., degenerative) and encounters for routine healing.
