Subluxation of C6/C7 cervical vertebrae, sequela

This code signifies a long-term consequence or late effect resulting from a previous, non-traumatic partial dislocation of the C6/C7 vertebrae in the neck. It indicates that the patient is currently experiencing issues directly attributable to that past subluxation, even if the original injury has healed.

Use this code when documentation clearly links current symptoms or conditions to a prior, resolved subluxation of the C6/C7 cervical vertebrae. This is appropriate for chronic pain, neurological deficits, or functional limitations that are a direct sequela of the original subluxation. Documentation must specify the C6/C7 level and confirm the sequela nature.

• Always sequence the code for the specific sequela (e.g., chronic pain, neurological deficit) first, followed by this sequela code.
• Ensure documentation explicitly states "sequela," "late effect," or clearly links current issues to a past subluxation.
• Do not use for acute or current subluxations; those require acute injury codes.
