Unsp traum displ spondylolysis of 5th cervcal vert, 7thG

This code describes a traumatic forward slippage of the fifth cervical vertebra (C5) over the vertebra below it, where the exact type of spondylolisthesis is not specified, and the vertebral fragments are not in their normal anatomical alignment. This particular code is used when the patient is receiving follow-up care for this fracture, and the healing process is taking longer than expected.

Use this code for a patient presenting for ongoing management of a previously diagnosed, unspecified, displaced traumatic C5 spondylolisthesis that is exhibiting delayed union or nonunion. Documentation should clearly indicate a traumatic etiology, displacement, involvement of the C5 vertebra, and the current encounter's purpose as follow-up for delayed fracture healing.

• Ensure documentation specifies "subsequent encounter" and "delayed healing" for this specific C5 fracture.
• Distinguish from initial encounters (A) or encounters for routine healing (D).
• Verify the traumatic nature of the spondylolisthesis; non-traumatic spondylolisthesis codes are found elsewhere.
