KATHERINE GILBERT, M.D. appears in the CMS NPPES registry as a Allergy Physician provider holding M.D. credentials at 3010 COLBY ST STE 118, BERKELEY, CA, 94705, with a listed phone of (510) 644-2316. NPI 1871814467 was issued on 06/17/2010. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what GILBERT 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 703 prescription claims written by this provider, covering 151 Medicare beneficiaries and totaling roughly $411K in drug spend, split 51% brand-name and 49% 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 69.9181/100 for the 2023 performance year (Quality 80.1542, Cost 21.2395), compared with the national average of 83.1.

Allergy Physician is a narrow specialty nationwide, with 1,019 enrolled providers across 49 states and an average of 755 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.
