STEVEN BLUMENTHAL, MD appears in the CMS NPPES registry as a Interventional Cardiology Physician provider holding MD credentials at 98 WOODCHUCK HOLLOW RD, COLD SPRING HARBOR, NY, 11724, with a listed phone of (516) 499-3964. NPI 1568441921 was issued on 01/13/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BLUMENTHAL 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 19,648 prescription claims written by this provider, covering 14,566 Medicare beneficiaries and totaling roughly $4.8 million in drug spend, split 93% brand-name and 7% generic by claim count, with an opioid prescribing rate of 0.1%. 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.

Interventional Cardiology Physician is a narrow specialty nationwide, with 3,382 enrolled providers across 53 states and an average of 2,984 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.
