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).

JUNG HYUN KO is a Neurology Physician provider practicing in DURHAM, North Carolina, according to the CMS National Plan and Provider Enumeration System (NPPES). NPI: 1205398492.

JUNG HYUN KO appears in the CMS NPPES registry as a Neurology Physician provider at 2301 ERWIN RD, DURHAM, NC, 27705, with a listed phone of (919) 684-8111. NPI 1205398492 was issued on 04/05/2019. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what KO 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 127 prescription claims written by this provider, covering 19 Medicare beneficiaries and totaling roughly $22K in drug spend, split 12% brand-name and 88% 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.
