Quality, Cost, Promoting Interoperability, and Improvement Activities composite score for the 2023 performance year. Specialty: Thoracic Surgery (Cardiothoracic Vascular Surgery) Physician.
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).
JAMES AMEIKA, M.D. appears in the CMS NPPES registry as a Thoracic Surgery (Cardiothoracic Vascular Surgery) Physician provider holding M.D. credentials at 75-167 HUALALAI RD STE 100, KAILUA KONA, HI, 96740, with a listed phone of (808) 331-8494. NPI 1851354393 was issued on 04/07/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what AMEIKA 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 2,094 prescription claims written by this provider, covering 332 Medicare beneficiaries and totaling roughly $338K in drug spend, split 12% brand-name and 88% generic by claim count.

Thoracic Surgery (Cardiothoracic Vascular Surgery) Physician is a mid-sized specialty nationwide, with 5,062 enrolled providers across 52 states and an average of 128 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.
