Magnetoencephalography/magnetic source imaging is INVESTIGATIONAL for all other conditions. Prior Authorization Information Inpatient • For services described in this policy, precertification/preauthorization IS REQUIRED for all products if the procedure is performed inpatient. Outpatient • For services described in this policy, see below for products where prior authorization might be required if the procedure is performed outpatient.
