MIPS score not measured
CMS assigned a neutral 75/100 threshold
CMS did not publish any Quality, Cost, Promoting Interoperability, or Improvement Activities category score for this clinician. This administrative threshold is not comparable with the national average of clinicians whose MIPS score was measured.
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).
