- vs 83.1 national avg · 2023 performance year
MIPS final score (Transplant Surgery Physician) - 72.5/100 vs national avg 83.1
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).
Jon Yamaguchi, MD appears in the CMS NPPES registry as a Transplant Surgery Physician provider holding MD credentials at 550 S BERETANIA ST, Honolulu, HI, 96813, with a listed phone of (808) 523-5033. NPI 1720006810 was issued on 07/17/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Yamaguchi 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 55 prescription claims written by this provider, covering 28 Medicare beneficiaries and totaling roughly $760 in drug spend, split 20% brand-name and 80% generic by claim count, with an opioid prescribing rate of 40.0%. These figures capture only Medicare Part D, commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 72.5/100 for the 2023 performance year (Quality 65.6, Cost 51.9), compared with the national average of 83.1.
Transplant Surgery Physician is a narrow specialty nationwide, with 1,026 enrolled providers across 48 states and an average of 275 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.
