Oth traum displ spondylolysis of sixth cervcal vert, 7thK

This code signifies a subsequent encounter for a patient experiencing a nonunion of a fracture related to a traumatic spondylolisthesis of the sixth cervical vertebra. This means the C6 vertebra has slipped forward due to a past injury, and the associated fracture has failed to heal properly.

Use this code when a patient presents for follow-up care, treatment, or monitoring of a previously diagnosed traumatic C6 spondylolisthesis where the associated fracture has not united. Documentation should clearly state "nonunion" of the fracture and specify the C6 level and traumatic etiology.

• Ensure documentation explicitly states "nonunion" of the fracture, not just delayed healing.
• Verify the encounter is "subsequent" and not the initial treatment for the fracture.
• Confirm the spondylolisthesis is "traumatic" and not congenital or degenerative.
