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).

TIMOTHY BEYER, O. D. is a Optometrist provider practicing in ALGONQUIN, Illinois, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: O. D.. NPI: 1760689160. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry. Provider information is self-reported to CMS and updated monthly.

TIMOTHY BEYER, O. D. appears in the CMS NPPES registry as a Optometrist provider holding O. D. credentials at 204 S MAIN ST, ALGONQUIN, IL, 60102, with a listed phone of (224) 678-9043. NPI 1760689160 was issued on 06/28/2007.

Medicare Part D records for calendar year 2023 show 31 prescription claims written by this provider, covering 11 Medicare beneficiaries and totaling roughly $6K in drug spend, split 74% brand-name and 26% generic by claim count.

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.
