KATHERINE LORSON, PHARMD appears in the CMS NPPES registry as a Ambulatory Care Pharmacist provider holding PHARMD credentials at 230 WORCESTER ST, WELLESLEY, MA, 02481, with a listed phone of (617) 972-5359. NPI 1568135986 was issued on 07/30/2021. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what LORSON 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 237 prescription claims written by this provider, covering 25 Medicare beneficiaries and totaling roughly $107K in drug spend, split 52% brand-name and 48% 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.

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.
