How MIPS and board certification work
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).
Heather Previs appears in the CMS NPPES registry as a Family Nurse Practitioner provider at 3426 MAIN ST, Stratford, CT, 06614, with a listed phone of (203) 318-0803. NPI 1477000370 was issued on 09/08/2016.
Medicare Part D records for calendar year 2023 show 8,808 prescription claims written by this provider, covering 549 Medicare beneficiaries and totaling roughly $1.1 million in drug spend, split 13% brand-name and 86% generic by claim count, with an opioid prescribing rate of 2.3%. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 94.2/100 for the 2023 performance year (Quality 81.9), compared with the national average of 83.1.
Family Nurse Practitioner is a high-volume specialty nationwide, with 210,832 enrolled providers across 56 states and an average of 1,222 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
