JENNIFER BOYCE, N.P. appears in the CMS NPPES registry as a Obstetrics & Gynecology Nurse Practitioner provider holding N.P. credentials at 110 TAMPICO STE 220, WALNUT CREEK, CA, 94598, with a listed phone of (925) 935-5356. NPI 1659670875 was issued on 03/28/2011. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BOYCE 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 664 prescription claims written by this provider, covering 230 Medicare beneficiaries and totaling roughly $565K in drug spend, split 6% brand-name and 94% 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.

Obstetrics & Gynecology Nurse Practitioner is a narrow specialty nationwide, with 2,864 enrolled providers across 52 states and an average of 232 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.
