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

This code signifies a fracture of the sixth cervical vertebra that is not in its normal anatomical alignment, and the bone has failed to heal properly after an initial treatment. This specific code is used when the patient is receiving follow-up care for this nonunion.

Apply this code for patients presenting for ongoing management of a previously treated, but unhealed, displaced C6 vertebral fracture. Documentation should clearly state "nonunion" and specify the encounter as subsequent care for the fracture. This code is appropriate when surgical intervention for nonunion, casting, or other non-operative treatments are being provided or monitored.

• Ensure documentation explicitly states "nonunion" and "displaced" for the C6 fracture.
• Verify the encounter is for subsequent care, not the initial treatment of the fracture.
• Consider sequencing this code with external cause codes (e.g., Y92.-) if the cause of the fracture is relevant and documented.
