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).

VANESSA SIEGRIST, APRN appears in the CMS NPPES registry as a Nurse Practitioner provider holding APRN credentials at 400 CAPITAL BLVD, ROCKY HILL, CT, 06067, with a listed phone of (860) 305-5420. NPI 1134663958 was issued on 12/13/2016.

Medicare Part D records for calendar year 2023 show 1,534 prescription claims written by this provider, covering 209 Medicare beneficiaries and totaling roughly $73K in drug spend, split 10% brand-name and 90% generic by claim count, with an opioid prescribing rate of 7.6%.

Nurse Practitioner is a high-volume specialty nationwide, with 87,227 enrolled providers across 56 states and an average of 1,084 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.
