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).

Robert Quilleash appears in the CMS NPPES registry as a Corneal and Contact Management Optometrist provider at 2200 W WAR MEMORIAL DR, Peoria, IL, 61613, with a listed phone of (309) 688-2161. NPI 1174717003 was issued on 09/04/2007.

Medicare Part D records for calendar year 2023 show 1,101 prescription claims written by this provider, covering 348 Medicare beneficiaries and totaling roughly $74K in drug spend, split 32% brand-name and 68% generic by claim count.

Before you book an appointment

Use this federal record as your verification checklist, not as a recommendation.

  • Confirm the NPI record is current in the official CMS registry, providers update their own NPPES details, and moves can lag. Verify this NPI
  • Check the active license and any disciplinary history with the Illinois medical board, federal registration is not a license check. Credential verification guide
  • Weigh a second option: compare this provider with a nearby Corneal and Contact Management Optometrist peer on Medicare volume and prescribing patterns. Compare providers
