Subluxation of T3/T4 thoracic vertebra, sequela

This code signifies a chronic or late-effect condition where the T3/T4 thoracic vertebrae are partially dislocated or misaligned. This subluxation is not an acute injury but rather a residual problem from a previous trauma or condition affecting this specific spinal segment.

Apply this code when documenting a patient presenting with ongoing symptoms directly attributable to a past subluxation of the T3/T4 thoracic vertebrae. This is appropriate for follow-up encounters or when the subluxation is a long-term consequence of an earlier event, such as chronic pain or neurological deficits.

• Ensure documentation clearly indicates the subluxation is a sequela, not an acute injury.
• Always code the underlying cause of the original subluxation if known and still relevant to the patient's care.
• This code requires a seventh character "S" for sequela, indicating a late effect.
