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).

JOSHUA BAKER, O.D. is a Optometrist provider practicing in DALLAS, North Carolina, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: O.D.. NPI: 1679577027.

JOSHUA BAKER, O.D. appears in the CMS NPPES registry as a Optometrist provider holding O.D. credentials at 820 LOWER DALLAS HWY, DALLAS, NC, 28034, with a listed phone of (704) 922-9808. NPI 1679577027 was issued on 06/13/2005.

Medicare Part D records for calendar year 2023 show 1,330 prescription claims written by this provider, covering 368 Medicare beneficiaries and totaling roughly $194K in drug spend, split 33% brand-name and 67% generic by claim count.

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.
