JENNIFER BRENNAN-PHILLIP, DO appears in the CMS NPPES registry as a Allergy & Immunology (Internal Medicine) Physician provider holding DO credentials at 4 TERRY DR STE 10, NEWTOWN, PA, 18940, with a listed phone of (215) 968-6000. NPI 1275193823 was issued on 06/17/2019. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BRENNAN-PHILLIP 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 339 prescription claims written by this provider, covering 86 Medicare beneficiaries and totaling roughly $557K in drug spend, split 49% brand-name and 51% 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.

Allergy & Immunology (Internal Medicine) Physician is a narrow specialty nationwide, with 520 enrolled providers across 48 states and an average of 798 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.
