KAITLYN CHU, NP appears in the CMS NPPES registry as a Oncology Registered Nurse provider holding NP credentials at 551 BOYLSTON ST STE 4, BOSTON, MA, 02116, with a listed phone of (617) 658-3421. NPI 1124784905 was issued on 11/16/2021. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CHU 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 52 prescription claims written by this provider, covering 29 Medicare beneficiaries and totaling roughly $179K in drug spend, split 21% brand-name and 79% 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 89.6632/100 for the 2023 performance year (Quality 76.6529, Cost 60.9286), compared with the national average of 83.1.

Oncology Registered Nurse is a narrow specialty nationwide, with 857 enrolled providers across 50 states and an average of 555 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.
