- Baseline tracings should be obtained prior to the surgical intervention; pre-procedural baseline studies are performed immediately prior to the proposed surgery for comparison with the studies performed during surgery.
- Each baseline study should be reported only once per operative session (American Academy of Neurology).
- Monitoring must be performed by qualified personnel acting within the scope of their license/certification as defined by state law or appropriate authorities; the IOM team must include a trained clinical neurophysiologist (MD or DO).
Key Coverage Criteria
- Continuous intraoperative neurophysiologic monitoring (IOM) is considered medically necessary when ALL of the following criteria are met: IOM is performed by either a licensed physician trained in clinical neurophysiology (e.g., a neurologist, physiatrist) or a trained technologist who is practicing within the scope of his/her state license /certification as defined by state law or appropriate authorities and is working under the direct supervision of a physician trained in neurophysiology and i [...]
- Continuous intraoperative neurophysiologic monitoring (IOM) is considered medically necessary when ALL of the following criteria are met: IOM is interpreted by a licensed physician trained in clinical neurophysiology, other than the operating surgeon or anesthesiologist, who is either physically in attendance in the operating suite or present by means of a real-time remote mechanism for all electroneurodiagnostic (END) monitoring situations and is immediately available to interpret the recording [...]
- Continuous intraoperative neurophysiologic monitoring (IOM) is considered medically necessary when ALL of the following criteria are met: Monitoring is conducted and interpreted real-time (either on-site or at a remote location) and continuously communicated to the surgical team.
- Continuous intraoperative neurophysiologic monitoring (IOM) is considered medically necessary when ALL of the following criteria are met: There is significant risk of brain, spinal cord, cranial nerve, or major peripheral nerve injury during a surgical procedure.
- Monitoring of a cranial nerve during head and/or neck surgery (e.g., resection of skull base tumor, resection of tumor involving a cranial nerve, cavernous sinus tumor, neck dissection, epileptogenic brain tumor/tissue resection).
- Monitoring of recurrent laryngeal nerve function during high-risk thyroid surgery (e.g., complete resection of a lobe of the thyroid, removal of the entire gland, malignancy, or following a prior thyroid surgery where there is scar tissue surrounding the laryngeal nerve).
