SILAS NWAISHIENYI, M.D appears in the CMS NPPES registry as a Emergency Medical Services (Emergency Medicine) Physician provider holding M.D credentials at 167 EVERGREEN DR, WESTBURY, NY, 11590, with a listed phone of (516) 610-8704. NPI 1336269802 was issued on 03/30/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what NWAISHIENYI 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 943 prescription claims written by this provider, covering 143 Medicare beneficiaries and totaling roughly $63K in drug spend, split 12% brand-name and 88% generic by claim count, with an opioid prescribing rate of 1.6%. 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 99.953/100 for the 2023 performance year (Quality 91.1861, Cost 92.8237), compared with the national average of 83.1.

Emergency Medical Services (Emergency Medicine) Physician is a narrow specialty nationwide, with 3,616 enrolled providers across 55 states and an average of 394 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.
