Answer: Code 61795 is an add-on code describing stereotactic computer-assisted volumetric (navigational) procedure, intracranial, extracranial or spinal (emphasis added), according to CPT. In addition, the National Correct Coding Initiative does not bundle 61795 to the laminectomy/fusion or instrumentation codes. Finally, stereotactic navigation allows the surgeon to place pedicle screws without damaging neuro/vascular tissues and thus reduce the risk of the surgery.
For all these reasons, the insurer should honor your claim for 61795 in this case, although many carriers are reluctant to pay for such navigation with extracranial or spinal procedures. You should appeal the insurer's decision, citing the CPT definition for 61795 and the inclusion of "spinal" in the code descriptor and requesting that the insurer's medical policy director review the claim.
