Provider Administrative Policy

Policy Date
May 2012
Revised/January 2013
Provider Type(s)


Our provider administrative policies contain information regarding claims submission, reimbursement, and other information in order to achieve an efficient relationship with our providers. These policies are not an authorization or explanation of benefits. Blue Cross of Idaho retains the right to add to, delete from and otherwise modify this policy in accordance with our provider contracts.


Intraoperative Monitoring

Intraoperative monitoring (IOM) is used to identify systemic compromises in a patient during a surgical procedure. The intent of the monitoring is to alert the surgeon of possible threats to the well-being of the patient so the surgeon may alter the course of the procedure in order to avoid permanent damage.

Blue Cross of Idaho will only consider allowing reimbursement for IOM when a licensed physician or other provider acting within the scope of his license performs the monitoring while in constant attendance in the operating room throughout the procedure. The provider performing IOM must be someone other than the operating surgeon or anesthesiologist. Additionally, the provider performing IOM must be recognized as a Covered Provider by BCI, as defined in PAP247 and able to bill independently under their own NPI. The surgeon (or surgical assist) performing the surgery or the anesthesiologist performing the surgical anesthesia are not eligible for additional reimbursement for IOM. We will not allow reimbursement for remote or on-line IOM.

CPT code 95940 is an add on code and can only be reported with the auditory evoked potential, EEG, EMG, nerve conduction study, evoked potential or the reflex test it is used with.

IOM is not indicated as medically necessary for all procedures. Blue Cross of Idaho may consider IOM services medically necessary during spinal, intracranial, or vascular procedures. However, these monitoring services are not clinically indicated for procedures on the parotid gland, thyroid or sinus. Therefore, CPT 95940 is not separately payable when billed by the surgeon performing any of the following procedures:

CPT 42300 – 42699
CPT 60210 – 60300
