XINGFU LIANG, MD appears in the CMS NPPES registry as a Critical Care Medicine (Anesthesiology) Physician provider holding MD credentials at 2365 QUIMBY RD STE 250, SAN JOSE, CA, 95122, with a listed phone of (650) 502-4770. NPI 1902225139 was issued on 04/15/2014. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what LIANG 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 362 prescription claims written by this provider, covering 43 Medicare beneficiaries and totaling roughly $36K in drug spend, split 10% brand-name and 90% generic by claim count, with an opioid prescribing rate of 52.2%. 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 94.9054/100 for the 2023 performance year (Quality 89.8108), compared with the national average of 83.1.

Critical Care Medicine (Anesthesiology) Physician is a narrow specialty nationwide, with 1,398 enrolled providers across 46 states and an average of 409 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.
