Unsp disp fx of sixth cervcal vert, subs for fx w nonunion

This code signifies a non-healing fracture of the sixth cervical vertebra that is displaced, meaning the bone fragments are not properly aligned. It indicates that the patient is receiving ongoing care for this specific fracture, which has failed to unite after an initial treatment attempt.

Use this code for follow-up encounters where a patient is being treated for a previously diagnosed, displaced C6 vertebral fracture that has not healed (nonunion). Documentation should clearly state "nonunion" or "failed fusion" of the C6 fracture, along with evidence of displacement and the subsequent nature of the encounter.

• Ensure documentation explicitly states "nonunion" for the C6 fracture; otherwise, a different subsequent encounter code may be more appropriate.
• Verify the specific cervical vertebra involved (C6) and the presence of displacement.
• This code requires an external cause code (e.g., W00-Y38) to describe the circumstances of the injury, if known and applicable.
