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).

Aimee Stefanski, MS, APRN, BS appears in the CMS NPPES registry as a Adult Health Nurse Practitioner provider holding MS, APRN, BS credentials at 79 WAWECUS ST, Norwich, CT, 06360, with a listed phone of (860) 886-2679. NPI 1104804392 was issued on 01/06/2006.

Medicare Part D records for calendar year 2023 show 212 prescription claims written by this provider, covering 53 Medicare beneficiaries and totaling roughly $52K in drug spend, split 20% brand-name and 80% 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 73.6/100 for the 2023 performance year (Quality 75.8, Cost 51.4), compared with the national average of 83.1.

Adult Health Nurse Practitioner is a mid-sized specialty nationwide, with 29,492 enrolled providers across 55 states and an average of 1,201 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.
