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).

DIANE DEWITT, O.D. is a Optometrist provider practicing in CLOVIS, New Mexico, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: O.D.. NPI: 1265412639. 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.

DIANE DEWITT, O.D. appears in the CMS NPPES registry as a Optometrist provider holding O.D. credentials at 1217 PILE ST, CLOVIS, NM, 88101, with a listed phone of (575) 763-5522. NPI 1265412639 was issued on 01/20/2006.

Medicare Part D records for calendar year 2023 show 277 prescription claims written by this provider, covering 81 Medicare beneficiaries and totaling roughly $39K in drug spend, split 40% brand-name and 60% 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.
