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).
Thuy Nguyen appears in the CMS NPPES registry as a Nurse Practitioner provider at 2102 SAN CLEMENTE AVE, Alhambra, CA, 91803, with a listed phone of (323) 580-3076. NPI 1073118907 was issued on 11/30/2020.
Medicare Part D records for calendar year 2023 show 277 prescription claims written by this provider, covering 47 Medicare beneficiaries and totaling roughly $25K in drug spend, split 12% brand-name and 88% generic by claim count. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 85.2/100 for the 2023 performance year (Quality 71.8, Cost 64.5), compared with the national average of 83.1.
Nurse Practitioner is a high-volume specialty nationwide, with 87,700 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.

- Confirm the NPI record is current in the official CMS registry, providers update their own NPPES details, and moves can lag. Verify this NPI
- Check the active license and any disciplinary history with the California medical board, federal registration is not a license check. Credential verification guide
- Weigh a second option: compare this provider with a nearby Nurse Practitioner peer on Medicare volume and prescribing patterns. Compare providers
