Effective October 1, 2013, IBC?s medical policy for intraoperative
neurophysiological monitoring (INM) will be updated. Medically necessary remote
(i.e., outside the operating room) and non-remote (i.e., inside the operating
room) INM will be covered when the physician is monitoring one individual at a
time. Previously, for remote and non-remote INM, monitoring of no more than
three cases simultaneously was covered. However, the beneficial results of INM
are demonstrated when a physician?s attention is focused on one individual at a
time due to the potential risk for morbidity.

[
]About INM[
]
INM refers to a variety of monitoring modalities used to ensure the integrity
of neural pathways during high-risk surgeries, including
vascular/cardiovascular, intracranial, endovascular, spine, orthopaedic,
peripheral nerve, and otolaryngologic surgeries. INM is distinct from clinical
diagnostic studies. The primary objective of INM is to identify and prevent
complications in the nervous system (the spinal cord or the brain), its blood
supply, or adjacent tissue, with the expectation that prompt intervention will
avert permanent deficits. The American Academy of Neurology recommends that INM
testing be reserved for surgical procedures in which there is a significant
risk of damage to neural integrity.
INM can identify new neurologic impairment, identify or separate nervous system
structures (e.g., around or in a tumor), and demonstrate which tracts or nerves
are still functional. INM may provide a surgeon with confirmation that no
complications have been detected up to a certain point. This allows the surgeon
to proceed with a more thorough surgical intervention.
