A patient with multiple spinal conditions, including previous fusion, severe kyphoscoliosis, and severe spinal and foraminal stenosis, presents for corrective surgery. Prior fusion instrumentation was removed, new instrumentation was placed, and a new fusion was performed in the lumbar spine.
In addition to the multiple spinal procedures performed, a NuVasive® VersaTie® polyethylene tether was woven through the interspinous ligaments via drill holes that were placed at the base of T8. The tether was returned in a weave fashion and after full tension was achieved, the tie was locked into place to the VersaTie® connectors that were placed at T11-T12. What is the appropriate root operation for placement of tether from T8-T12?
Do not assign an additional code for the placement of the VersaTie® tether. Fixation instrumentation is integral to the fusion procedure and no additional code is assigned.
