NIKHIL WARRIER, M.D. appears in the CMS NPPES registry as a Clinical Cardiac Electrophysiology Physician provider holding M.D. credentials at 18111 BROOKHURST ST STE 5100, FOUNTAIN VALLEY, CA, 92708, with a listed phone of (714) 546-2238. NPI 1538486675 was issued on 04/29/2010. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what WARRIER most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D records for calendar year 2023 show 3,315 prescription claims written by this provider, covering 572 Medicare beneficiaries and totaling roughly $1.1 million in drug spend, split 31% brand-name and 69% generic by claim count. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 88.6039/100 for the 2023 performance year (Quality 87.5003, Cost 54.709), compared with the national average of 83.1.

Clinical Cardiac Electrophysiology Physician is a narrow specialty nationwide, with 1,570 enrolled providers across 52 states and an average of 1,596 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist — always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
