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).

CHELSEA TRIERWEILER, FNP appears in the CMS NPPES registry as a Nurse Practitioner provider holding FNP credentials at 7280 LAGAE RD STE J, CASTLE PINES, CO, 80108, with a listed phone of (303) 814-0505. NPI 1679104483 was issued on 01/30/2020.

Medicare Part D records for calendar year 2023 show 501 prescription claims written by this provider, covering 103 Medicare beneficiaries and totaling roughly $98K in drug spend, split 16% brand-name and 84% generic by claim count.

On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 88.2296/100 for the 2023 performance year (Quality 88.9629), compared with the national average of 83.1.

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.
