You report several EEG codes such as 95812 (Electroencephalogram [EEG] extended monitoring; 41-60 minutes) and 95813 (… greater than 1 hour) based on the amount of recording time. But what constitutes recording time?

Jeffrey Cozzens, MD, professor and chair of the neurosurgery division of Southern Illinois University School of Medicine and a presenter at the AMA’s CPT and RBRVS 2011 Annual Symposium in Chicago, addressed the issue during his presentation about neurosurgery and neurology changes for 2011. Keep two things in mind when calculating recording time for these EEGs:

• Recording time is when the recording is underway and the healthcare provider is collecting data.
• Recording time excludes set-up and take-down time.

Other EEG codes, however, focus on the amount of physician time rather than recording time. Watch for that specificity in guidelines for 95961 (Functional cortical and subcortical mapping by stimulation and/or recording of electrodes or brain surface, or of depth electrodes, to provoke seizures or identify vital brain structures; initial hour of physician attendance) and +95962 (… each additional hour of physician attendance [List separately in addition to code for primary procedure). If the physician is in attendance for a total of 30 minutes or less, only report 95961 and append modifier 52 (Reduced services) to indicate he didn’t fulfill the full hour represented by the code.

Two codes for special EEG tests now specify who attends during the procedure:

• 95953 -- Monitoring for localization of cerebral seizure focus by computerized portable 16 or more channel EEG, electroencephalographic (EEG) recording and interpretation, each 24 hours, unattended
• 95956 -- Monitoring for localization of cerebral seizure focus by cable or radio, 16 or more channel telemetry, electroencephalographic (EEG) recording and interpretation, each 24 hours, attended by a technologist or nurse.
