HANI HASSOUN, MD appears in the CMS NPPES registry as a Hematology (Internal Medicine) Physician provider holding MD credentials at 1275 YORK AVE, NEW YORK, NY, 10021, with a listed phone of (212) 639-2000. NPI 1285605220 was issued on 01/29/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what HASSOUN 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 889 prescription claims written by this provider, covering 122 Medicare beneficiaries and totaling roughly $3.9 million in drug spend, split 23% brand-name and 77% generic by claim count, with an opioid prescribing rate of 2.0%. 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 79.0323/100 for the 2023 performance year (Quality 69.4497), compared with the national average of 83.1.

Hematology (Internal Medicine) Physician is a narrow specialty nationwide, with 1,436 enrolled providers across 50 states and an average of 693 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.
