Subluxation of T9/T10 thoracic vertebra, sequela

This code signifies a long-term or late-effect condition resulting from a previous partial dislocation of the thoracic vertebra between T9 and T10. It indicates that the patient is experiencing ongoing symptoms or complications directly attributable to this past spinal injury, rather than an acute event.

Apply this code when documentation clearly states a patient's current symptoms (e.g., chronic pain, neurological deficits, limited range of motion) are a direct sequela of a previously diagnosed T9/T10 subluxation. This is appropriate for follow-up visits addressing persistent issues from the original injury, even if the subluxation itself is no longer acutely present.

• Always sequence this code after the primary diagnosis describing the current manifestation of the sequela (e.g., chronic back pain, radiculopathy).
• Ensure the medical record explicitly links the current condition to a past T9/T10 subluxation.
• Do not use this code for an acute or current subluxation; specific acute codes exist for that scenario.
