In simple words: This procedure involves modifying, changing, or removing a system of screws and a flexible cable in the upper and middle back used to correct spinal curvature.A small camera might be used during the procedure.

This code encompasses procedures involving the revision, replacement, or removal of a system of screws and a flexible cable used in thoracic vertebral body tethering.Thoracoscopy may be used to visualize and access the surgical site. Revision may involve adjusting or modifying the previously placed tethering and screws, while replacement involves exchanging the existing system with new components. Removal involves taking out the screws and cord.This procedure is typically used to treat spinal curvature, such as that caused by scoliosis.

Example 1: A patient with scoliosis who underwent thoracic vertebral body tethering experiences loosening of the screws, requiring revision to tighten or reposition them., A patient with scoliosis requires replacement of their vertebral body tethering system due to material fatigue or failure of the original system., A patient with scoliosis who has completed growth requires removal of their thoracic vertebral body tethering system.

Documentation should include the reason for the revision, replacement, or removal, the specific components involved, operative details, use of thoracoscopy (if applicable), and any complications encountered.
