DAVID WORTHINGTON, PHARMD appears in the CMS NPPES registry as a Ambulatory Care Pharmacist provider holding PHARMD credentials at 1901 S UNION AVE STE 7009, TACOMA, WA, 98405, with a listed phone of (253) 459-6746. NPI 1336716794 was issued on 06/04/2021. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what WORTHINGTON 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 795 prescription claims written by this provider, covering 388 Medicare beneficiaries and totaling roughly $189K in drug spend, split 22% brand-name and 78% 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.

Ambulatory Care Pharmacist is a narrow specialty nationwide, with 3,473 enrolled providers across 52 states and an average of 492 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.
