GEORGE BLESSIOS, MD appears in the CMS NPPES registry as a Transplant Surgery Physician provider holding MD credentials at 100 COLLEGE PKWY STE 120, WILLIAMSVILLE, NY, 14221, with a listed phone of (716) 480-2203. NPI 1669472080 was issued on 07/28/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BLESSIOS 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 166 prescription claims written by this provider, covering 62 Medicare beneficiaries and totaling roughly $23K in drug spend, split 32% brand-name and 68% generic by claim count, with an opioid prescribing rate of 32.5%. 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.

Transplant Surgery Physician is a narrow specialty nationwide, with 1,026 enrolled providers across 48 states and an average of 275 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.
