What G0453 covers

G0453 covers real-time neurophysiologic monitoring during an operation when the monitoring professional is outside the operating room, such as at a remote workstation. The professional observes patient-specific signals during surgery and communicates clinically significant changes to the operating team. It is used for procedures in which ongoing monitoring can help the surgical team identify changes in neural function, including some spine and brain operations.

Report the service by patient and in 15-minute units, based on the time spent providing continuous monitoring. The record should identify the operation, monitoring professional, signals followed, monitoring start and stop times, significant signal changes, and communications with the surgical team. CMS assigns work, practice-expense, and malpractice relative value units to the service.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

G0453 billing questions

When should G0453 be chosen instead of 95940?

G0453 is for continuous monitoring performed from outside the operating room, including remotely. Code 95940 describes monitoring performed in the operating room.

How are units counted?

The code is reported per patient in 15-minute units. Document the monitoring interval with start and stop times.

What documentation supports G0453?

Document the surgical procedure, the signals monitored, the monitoring professional and monitoring times. Record important signal changes and communications to the operating team.

Is G0453 the same as an evoked-potential test?

No. G0453 represents continuous monitoring during surgery; codes such as 95938 identify specific evoked-potential testing.

How does G0453 differ from 95941?

Both concern continuous monitoring from outside the operating room, but G0453 is reported per 15 minutes and 95941 uses an hourly unit.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
