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).

MICHAEL CHOI, M.D. is a Cornea and External Diseases Specialist Physician provider practicing in BUENA PARK, California, according to the CMS National Plan and Provider Enumeration System (NPPES).

MICHAEL CHOI, M.D. appears in the CMS NPPES registry as a Cornea and External Diseases Specialist Physician provider holding M.D. credentials at 6102 BEACH BLVD, BUENA PARK, CA, 90621, with a listed phone of (714) 868-7733. NPI 1871912279 was issued on 04/14/2014.

Medicare Part D records for calendar year 2023 show 3,065 prescription claims written by this provider, covering 557 Medicare beneficiaries and totaling roughly $828K in drug spend, split 54% brand-name and 46% 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.
