VICTOR LIOU, MD appears in the CMS NPPES registry as a Ophthalmic Plastic and Reconstructive Surgery Physician provider holding MD credentials at 1650 LOS GAMOS DR, SAN RAFAEL, CA, 94903, with a listed phone of (415) 492-5400. NPI 1831586015 was issued on 04/24/2015. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what LIOU 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 553 prescription claims written by this provider, covering 258 Medicare beneficiaries and totaling roughly $8K in drug spend, split 8% brand-name and 92% generic by claim count, with an opioid prescribing rate of 15.2%. 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 91.9066/100 for the 2023 performance year (Quality 79.1694, Cost 94.686), compared with the national average of 83.1.

Ophthalmic Plastic and Reconstructive Surgery Physician is a narrow specialty nationwide, with 291 enrolled providers across 46 states and an average of 624 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.
