Unspecified nondisp fx of sixth cervical vertebra, sequela

This code signifies a long-term complication or late effect stemming from a previously sustained, unspecified nondisplaced fracture of the sixth cervical vertebra. It indicates that the initial injury has healed, but residual issues or conditions related to that fracture are now being addressed.

Apply this code when a patient presents with a current condition directly resulting from a past, healed nondisplaced fracture of the C6 vertebra. Documentation should clearly link the current complaint to the historical fracture, often noted as "due to old C6 fracture" or "sequela of prior C6 injury."

• Always sequence the sequela code first, followed by codes for the specific residual condition(s) being treated (e.g., chronic pain, nerve impingement).
• Ensure documentation explicitly states the C6 fracture was "nondisplaced" and that the current issue is a "sequela" or "late effect."
• Do not use for acute or subacute fractures; those require codes from the initial injury categories.
