The Merit-based Incentive Payment System (MIPS) scores providers 0–100 across four performance categories: Quality, Cost, Promoting Interoperability, and Improvement Activities, weighted under 42 CFR §414.1380. Reporting is voluntary for many small practices, so absence of a MIPS score is not a quality signal.

Board certification through an ABMS or AOA member board signals voluntary post-licensure examination plus continuous Maintenance of Certification cycles. Verify any individual provider's status through certificationmatters.org (ABMS) or osteopathic.org (AOA).

JULIE NGUYEN, NP appears in the CMS NPPES registry as a Registered Nurse provider holding NP credentials at 1 CELLINI PL STE 102, WEST HAVEN, CT, 06516, with a listed phone of (203) 932-6481. NPI 1649521246 was issued on 09/24/2012.

Medicare Part D records for calendar year 2023 show 435 prescription claims written by this provider, covering 62 Medicare beneficiaries and totaling roughly $23K in drug spend, split 23% brand-name and 77% generic by claim count.

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.

Registered Nurse is a high-volume specialty nationwide, with 175,652 enrolled providers across 56 states and an average of 1,000 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.
