MIPS final score (Low Vision Rehabilitation Optometrist) — 81.5711/100 vs national avg 83.1

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).

THOMAS PORTER, OD appears in the CMS NPPES registry as a Low Vision Rehabilitation Optometrist provider holding OD credentials at 1225 S GRAND BLVD, SAINT LOUIS, MO, 63104, with a listed phone of (314) 977-5200. NPI 1265496871 was issued on 04/12/2006.

Medicare Part D records for calendar year 2023 show 237 prescription claims written by this provider, covering 64 Medicare beneficiaries and totaling roughly $43K in drug spend, split 47% brand-name and 53% generic by claim count.

Low Vision Rehabilitation Optometrist is a narrow specialty nationwide, with 299 enrolled providers across 39 states and an average of 296 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.
