How Pain Medicine (Physical Medicine & Rehabilitation) Physician compares to other specialties among Oklahoma 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).
Kelly Volk, DO appears in the CMS NPPES registry as a Pain Medicine (Physical Medicine & Rehabilitation) Physician provider holding DO credentials at 2488 E 81ST ST STE 290, Tulsa, OK, 74137, with a listed phone of (918) 494-2665. NPI 1538474648 was issued on 08/12/2010.
Medicare Part D records for calendar year 2023 show 831 prescription claims written by this provider, covering 109 Medicare beneficiaries and totaling roughly $82K in drug spend, split 9% brand-name and 91% generic by claim count, with an opioid prescribing rate of 49.6%. 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.
Pain Medicine (Physical Medicine & Rehabilitation) Physician is a narrow specialty nationwide, with 1,630 enrolled providers across 50 states and an average of 1,401 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
