What 95940 covers
This service covers a physician’s or qualified health care professional’s personal, one-on-one attention to neurophysiologic monitoring during an operation in the operating room. Monitoring may include signals such as somatosensory or motor evoked potentials, EEG, or EMG. It is commonly used during spine procedures, including decompression and fusion, when changes in neural signals may alert the surgical team to potential injury. The monitoring professional observes the signals and communicates relevant changes to the operative team; the surgeon’s procedure itself is not the monitoring service.
Report the time spent providing this dedicated monitoring in 15-minute units. The record should identify the patient and operation, monitoring modalities, the monitoring professional, start and stop times, interruptions, and significant findings or communications. The operative report alone may not establish the monitoring time, so retain documentation from the professional who performed or supervised the service. Select this code for one-patient, personally attended monitoring in the operating room; monitoring from outside the room or involving more than one case has a different reporting circumstance.

95940 billing questions
How does 95940 differ from 95941?

How are the units determined?
The code is reported in 15-minute units for the time spent providing the qualifying monitoring service. Keep start and stop times and note interruptions in the monitoring record.
What documentation supports the service?
Document the operation, monitoring modalities, the professional providing the service, the monitoring interval, interruptions, signal changes, and communications with the surgical team.

No. It represents attended intraoperative neurophysiology monitoring, not the decompression, fusion, or other surgical work.
Can the code be used when the monitor watches multiple cases?
95940 is for attention directed exclusively to one patient in the operating room. Monitoring more than one case has a different reporting circumstance.
