MARNA MOORE-BARR, FNP appears in the CMS NPPES registry as a Lactation Consultant (Registered Nurse) provider holding FNP credentials at 1050 LAS TABLAS RD STE 13, TEMPLETON, CA, 93465, with a listed phone of (805) 285-7557. NPI 1013395821 was issued on 05/12/2015. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MOORE-BARR 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 230 prescription claims written by this provider, covering 58 Medicare beneficiaries and totaling roughly $68K in drug spend, split 41% brand-name and 59% 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.

Lactation Consultant (Registered Nurse) is a narrow specialty nationwide, with 3,799 enrolled providers across 53 states and an average of 560 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.
