M43.5X4
ICD-10-CMThis code signifies a condition where a vertebra in the thoracic spine has repeatedly shifted out of its normal alignment with an adjacent vertebra. This dislocation is not a new, acute event but rather a recurring issue, indicating instability in the thoracic spinal segment.
Apply this code when documentation clearly indicates a recurrent dislocation of a thoracic vertebra. This is appropriate for patients presenting with symptoms related to chronic thoracic spinal instability, such as pain, neurological deficits, or limited range of motion, where previous episodes of dislocation have been noted.
