ROBERT ANDONIAN, PHARM D. appears in the CMS NPPES registry as a Pharmacist Clinician (PhC)/ Clinical Pharmacy Specialist provider holding PHARM D. credentials at 5020 S C ST, OXNARD, CA, 93033, with a listed phone of (805) 240-9962. NPI 1033564745 was issued on 05/01/2016. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ANDONIAN 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 11 prescription claims written by this provider, covering N/A Medicare beneficiaries and totaling roughly $2K in drug spend, split 100% brand-name and 0% 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.

Pharmacist Clinician (PhC)/ Clinical Pharmacy Specialist is a mid-sized specialty nationwide, with 12,377 enrolled providers across 55 states and an average of 256 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
