Unsp traum nondisp spondylolysis of 3rd cervcal vert, 7thK

This code signifies a non-displaced traumatic spondylolisthesis of the C3 vertebra where the specific type of spondylolisthesis is not documented. The patient is in a subsequent phase of care, specifically for a fracture that has failed to heal (nonunion).

Use this code for follow-up encounters of a C3 traumatic spondylolisthesis with documented nonunion, when the initial displacement was non-displaced and the specific type of spondylolisthesis is not further specified. Documentation should clearly indicate "subsequent encounter," "nonunion," and "C3 vertebra."

• Ensure documentation specifies "nonunion" for the subsequent encounter.
• Distinguish from initial encounters (A) or sequela (S) codes for this condition.
• Verify the cervical level (C3) is clearly documented; do not use for other cervical vertebrae.
