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).

On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 57/100 for the 2023 performance year (Quality 15.6, Cost 63.5), compared with the national average of 83.1.
Adult Medicine Physician is a narrow specialty nationwide, with 2,481 enrolled providers across 52 states and an average of 2,807 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
