MARYAM ATASHBAR, NURSE PRACTITIONER appears in the CMS NPPES registry as a Case Manager/Care Coordinator provider holding NURSE PRACTITIONER credentials at 2240 E GONZALES RD, OXNARD, CA, 93036, with a listed phone of (805) 981-5181. NPI 1720482110 was issued on 10/14/2014. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ATASHBAR 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 183 prescription claims written by this provider, covering 116 Medicare beneficiaries and totaling roughly $6K in drug spend. 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.

Case Manager/Care Coordinator is a high-volume specialty nationwide, with 160,120 enrolled providers across 54 states and an average of 859 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.
