Subluxation of T1/T2 thoracic vertebra, sequela

This code signifies a long-term or late effect resulting from a previous partial dislocation of the thoracic vertebra located between the first and second segments (T1/T2). The initial injury has resolved, but residual symptoms or conditions persist due to the prior subluxation. This could include chronic pain, instability, or neurological deficits.

Use this code when documenting conditions that are a direct consequence of a past T1/T2 subluxation, even if the subluxation itself is no longer acutely present. This applies to patients presenting with chronic issues such as persistent localized pain, limited range of motion, or nerve impingement that are attributed to the historical injury. It is appropriate when the initial injury occurred more than one year prior or when the acute phase has definitively passed.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., chronic pain, radiculopathy).
• Ensure documentation clearly links the current condition to the historical T1/T2 subluxation.
• Do not use for acute or current subluxations; those require codes from the acute injury section.
