How Obstetrics & Gynecology Physician compares to other specialties among Missouri providers
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).
Kristy McCall, MD appears in the CMS NPPES registry as an Obstetrics & Gynecology Physician provider holding MD credentials at 1000 E PRIMROSE ST, Springfield, MO, 65807, with a listed phone of (417) 269-7900. NPI 1821030958 was issued on 06/12/2006.
Medicare Part D records for calendar year 2023 show 52 prescription claims written by this provider, covering 24 Medicare beneficiaries and totaling roughly $1K in drug spend, split 31% brand-name and 69% generic by claim count. 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.
Obstetrics & Gynecology Physician is a mid-sized specialty nationwide, with 44,326 enrolled providers across 56 states and an average of 179 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
