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).

Shawn Dawson, M.D. appears in the CMS NPPES registry as a Family Medicine Physician provider holding M.D. credentials at 1013 PENNSYLVANIA AVE, Ottumwa, IA, 52501, with a listed phone of (641) 683-6868. NPI 1306834577 was issued on 10/11/2005.

Medicare Part D records for calendar year 2023 show 16,119 prescription claims written by this provider, covering 785 Medicare beneficiaries and totaling roughly $1.6 million in drug spend, split 14% brand-name and 85% generic by claim count, with an opioid prescribing rate of 8.1%. On the CMS Merit-based Incentive Payment System, this provider carries a Final Score of 75/100 for the 2023 performance year, but CMS published no Quality, Promoting Interoperability, Improvement Activity or Cost score: this is the neutral performance threshold CMS assigns where nothing was scored, so it is not comparable with clinicians whose score was measured.
