WALTER ZAVALA-SALAS, RPA-C appears in the CMS NPPES registry as a Phlebotomy Technician provider holding RPA-C credentials at 593 E TREMONT AVE, BRONX, NY, 10457, with a listed phone of (347) 867-9059. NPI 1689034654 was issued on 03/03/2016. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ZAVALA-SALAS 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 1,913 prescription claims written by this provider, covering 343 Medicare beneficiaries and totaling roughly $605K in drug spend, split 22% brand-name and 78% 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.

Phlebotomy Technician is a narrow specialty nationwide, with 2,535 enrolled providers across 51 states and an average of 656 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.
