DAVID VANMATER, MD appears in the CMS NPPES registry as a Pediatric Hematology & Oncology Physician provider holding MD credentials at DUKE UNIVERSITY MEDICAL CENTER, DURHAM, NC, 27710, with a listed phone of (919) 684-3401. NPI 1437374584 was issued on 04/16/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what VANMATER 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 33 prescription claims written by this provider, covering N/A Medicare beneficiaries and totaling roughly $333 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.

Pediatric Hematology & Oncology Physician is a narrow specialty nationwide, with 2,568 enrolled providers across 52 states and an average of 92 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.
