MICHELLE BRASSINGTON, APRN appears in the CMS NPPES registry as a Gerontology Registered Nurse provider holding APRN credentials at 1 CELLINI PL STE 102, WEST HAVEN, CT, 06516, with a listed phone of (203) 932-6481. NPI 1225259989 was issued on 05/01/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BRASSINGTON 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 3,358 prescription claims written by this provider, covering 337 Medicare beneficiaries and totaling roughly $186K in drug spend, split 20% brand-name and 80% generic by claim count, with an opioid prescribing rate of 4.6%. 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 90.7483/100 for the 2023 performance year (Quality 82.2742, Cost 58.9275), compared with the national average of 83.1.

Gerontology Registered Nurse is a narrow specialty nationwide, with 749 enrolled providers across 48 states and an average of 1,721 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.
