Subluxation of T8/T9 thoracic vertebra, sequela

This code indicates a persistent or late-effect condition resulting from a previous subluxation of the thoracic vertebra at the T8-T9 level. A subluxation refers to a partial dislocation or misalignment of the vertebral joint. The "sequela" designation signifies that the current clinical presentation is a residual effect of that past injury, rather than an acute event.

This code is appropriate for documenting chronic pain, limited range of motion, neurological deficits, or other long-term complications directly attributable to a prior T8-T9 subluxation. It should be used when the acute phase of the original injury has passed, and the patient is being treated for the lasting consequences.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., chronic pain, myelopathy).
• Ensure documentation clearly links the current condition to a past T8-T9 subluxation.
• Do not use for acute or current subluxations; those require codes from the S23.15- category without the "S" seventh character.
