Coverage indications
Stereotaxic depth electrode implantation prior to surgical treatment of focal epilepsy for patients who are unresponsive to anticonvulsant medications has been found both safe and effective for diagnosing resectable seizure foci that may go undetected by conventional scalp EEGs.
Documentation requirements
Item/Service Description: The procedure employs thin wire electrodes which are implanted in the brain of the focal epileptic patient for electroencephalograph (EEG) monitoring. By taking several readings during seizure activity, the location of the epileptic focus may be found, so that better informed decisions can be made regarding the surgical treatment of persons with intractable seizures. Benefit Categories: 20 - Diagnostic Tests (other)
