Quality, Cost, Promoting Interoperability, and Improvement Activities composite score for the 2023 performance year. Specialty: Pediatric Nephrology Physician. Quality dim: 82.9618. Cost dim: 69.652.
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).
RHIANA LAU, M.D. is a Pediatric Nephrology Physician provider practicing in HONOLULU, Hawaii, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D..

RHIANA LAU, M.D. appears in the CMS NPPES registry as a Pediatric Nephrology Physician provider holding M.D. credentials at 1314 S KING ST STE 415, HONOLULU, HI, 96814, with a listed phone of (808) 592-3250. NPI 1801095682 was issued on 07/12/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what LAU 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 34 prescription claims written by this provider, covering N/A Medicare beneficiaries and totaling roughly $19K in drug spend, split 41% brand-name and 59% generic by claim count. 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.

Pediatric Nephrology Physician is a narrow specialty nationwide, with 723 enrolled providers across 50 states and an average of 97 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.
