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).

ERIC CHEN, M.D. appears in the CMS NPPES registry as a Diagnostic Radiology Physician provider holding M.D. credentials at 3288 MOANALUA RD, HONOLULU, HI, 96819, with a listed phone of (808) 432-0000. NPI 1366640641 was issued on 07/06/2007.

Medicare Part D records for calendar year 2023 show 18 prescription claims written by this provider, covering 11 Medicare beneficiaries and totaling roughly $128 in drug spend.

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.
