MARIA VARGAS-SANTOS, M.D. appears in the CMS NPPES registry as a Personal Emergency Response Attendant provider holding M.D. credentials at HC 2 BOX 11347, SAN GERMAN, PR, 00683, with a listed phone of (787) 264-2178. NPI 1255380895 was issued on 05/10/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what VARGAS-SANTOS 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 760 prescription claims written by this provider, covering 73 Medicare beneficiaries and totaling roughly $12K in drug spend, split 5% brand-name and 95% 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.

Personal Emergency Response Attendant is a narrow specialty nationwide, with 830 enrolled providers across 48 states and an average of 996 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.
