ANNETTE FEIGENBAUM, M.D. appears in the CMS NPPES registry as a Medical Biochemical Genetics provider holding M.D. credentials at 7920 FROST ST STE 200, SAN DIEGO, CA, 92123, with a listed phone of (858) 576-1700. NPI 1902187859 was issued on 09/06/2011. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what FEIGENBAUM 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 32 prescription claims written by this provider, covering N/A Medicare beneficiaries and totaling roughly $818K in drug spend, split 97% brand-name and 3% 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.

Medical Biochemical Genetics is a narrow specialty nationwide, with 21 enrolled providers across 13 states and an average of 29 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.
