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).

COLIN KINJO is a Optometrist provider practicing in SPARKS, Nevada, according to the CMS National Plan and Provider Enumeration System (NPPES). NPI: 1619366531.

COLIN KINJO appears in the CMS NPPES registry as a Optometrist provider at 5961 S LOS ALTOS PKWY, SPARKS, NV, 89436, with a listed phone of (775) 359-2020. NPI 1619366531 was issued on 01/15/2015. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what KINJO most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D records for calendar year 2023 show 43 prescription claims written by this provider, covering 20 Medicare beneficiaries and totaling roughly $1K in drug spend, split 28% brand-name and 72% 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.
