NIZAR SENUSSI, MD appears in the CMS NPPES registry as a Hepatology Physician provider holding MD credentials at 875 OAK ST SE STE C3010, SALEM, OR, 97301, with a listed phone of (503) 399-7520. NPI 1174964878 was issued on 07/10/2013. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what SENUSSI 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 128 prescription claims written by this provider, covering 101 Medicare beneficiaries and totaling roughly $19K in drug spend, split 21% brand-name and 79% 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 79.9742/100 for the 2023 performance year (Quality 69.6772, Cost 63.5703), compared with the national average of 83.1.

Hepatology Physician is a narrow specialty nationwide, with 281 enrolled providers across 36 states and an average of 803 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.
