CLAUDIA CHAVES, M.D. appears in the CMS NPPES registry as a Vascular Neurology Physician provider holding M.D. credentials at 2000 WASHINGTON ST STE 567, NEWTON, MA, 02462, with a listed phone of (617) 928-1500. NPI 1740241736 was issued on 03/29/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CHAVES 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 1,159 prescription claims written by this provider, covering 219 Medicare beneficiaries and totaling roughly $415K in drug spend, split 10% brand-name and 90% generic by claim count. 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 Neurology Physician is a narrow specialty nationwide, with 555 enrolled providers across 47 states and an average of 378 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.
