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).

PHUONG NGUYEN, D.O. is a Surgery Physician provider practicing in COLFAX, Washington, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: D.O.. NPI: 1275947103.

PHUONG NGUYEN, D.O. appears in the CMS NPPES registry as a Surgery Physician provider holding D.O. credentials at 1055 W FAIRVIEW ST STE B, COLFAX, WA, 99111, with a listed phone of (509) 397-2675. NPI 1275947103 was issued on 06/18/2014.

Surgery Physician is a mid-sized specialty nationwide, with 36,191 enrolled providers across 56 states and an average of 169 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.
