DAVID FELDSTEIN, MD appears in the CMS NPPES registry as a Vascular & Interventional Radiology Physician provider holding MD credentials at 2501 KUSER RD, HAMILTON, NJ, 08691, with a listed phone of (609) 585-8800. NPI 1386958007 was issued on 08/05/2010. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what FELDSTEIN 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 14 prescription claims written by this provider, covering N/A Medicare beneficiaries and totaling roughly $154 in drug spend. 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.

Vascular & Interventional Radiology Physician is a narrow specialty nationwide, with 2,981 enrolled providers across 53 states and an average of 72 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.
