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).

Medicare Part D records for calendar year 2023 show 7,318 prescription claims written by this provider, covering 594 Medicare beneficiaries and totaling roughly $934K in drug spend, split 15% brand-name and 84% generic by claim count, with an opioid prescribing rate of 3.4%. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 80.9/100 for the 2023 performance year (Quality 69.8, Cost 68.1), compared with the national average of 83.1.
