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).

GEOFFREY SNEDDON, OD appears in the CMS NPPES registry as a Optometrist provider holding OD credentials at 1200 W DEYOUNG ST, MARION, IL, 62959, with a listed phone of (618) 993-5686. NPI 1720026321 was issued on 06/04/2006.

Medicare Part D records for calendar year 2023 show 202 prescription claims written by this provider, covering 54 Medicare beneficiaries and totaling roughly $12K in drug spend, split 19% brand-name and 81% generic by claim count.

On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 81.1212/100 for the 2023 performance year (Quality 100, Cost 20.404), compared with the national average of 83.1.

Optometrist is a high-volume specialty nationwide, with 60,463 enrolled providers across 56 states and an average of 257 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist — always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
