Dislocation of T12/L1 thoracic vertebra, sequela

This code signifies a long-term complication or residual effect stemming from a prior dislocation of the T12/L1 vertebral segment. These sequelae can include chronic pain, neurological deficits, instability, or degenerative changes that persist after the initial injury has healed.

Apply this code when documenting conditions that are a direct consequence of a T12/L1 vertebral dislocation that occurred in the past. This is appropriate for follow-up encounters where the patient is being treated for ongoing issues related to the old injury, rather than the acute dislocation itself.

• Always use this code as a secondary diagnosis, with the primary code describing the specific sequela (e.g., chronic pain, radiculopathy).
• Ensure documentation clearly links the current condition to the previous T12/L1 dislocation.
• Do not use for acute or subacute dislocations; those require codes from the acute injury chapter.
