CPT code 95721: EEG interpretation, over 36, under 60 hours2026 Medicare rate & RVUs in California

Medicare pays $223.05–$262.20 for 95721 in the office in California, from Chico, CA to San Benito County, CA. Which amount applies depends on the service address.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 95721 covers

Code 95721 represents a neurologist’s or other qualified health care professional’s review and interpretation of a prolonged EEG recording, followed by a diagnostic report. It applies when the recording lasts more than 36 but less than 60 hours and has no synchronized video. Such studies may evaluate recurrent spells, suspected seizures, or altered mental status when a brief EEG is insufficient, in hospital or ambulatory monitoring settings. The service is the professional analysis and report, rather than electrode application or technologist acquisition work.

Select the code from the recording duration and whether video was captured. Documentation should support the recording’s dates and times, total duration, lack of video, findings, and professional interpretation. CMS assigns work and practice-expense relative values to this service; the record should substantiate the professional work for the reported study.
