DORIS GALINA-DA SILVA, DORIS GALINADA SILVA appears in the CMS NPPES registry as a Nephrology Physician provider holding DORIS GALINADA SILVA credentials at 2370 COUNTRY HILLS DR STE 101, ANTIOCH, CA, 94509, with a listed phone of (925) 779-9635. NPI 1043528979 was issued on 09/14/2010. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what GALINA-DA SILVA 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 1,268 prescription claims written by this provider, covering 197 Medicare beneficiaries and totaling roughly $198K in drug spend, split 17% brand-name and 83% 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.

Nephrology Physician is a mid-sized specialty nationwide, with 10,534 enrolled providers across 55 states and an average of 1,454 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.

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.
