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).
ANDREW SHYU, MD is a Ophthalmology Physician provider practicing in WILMINGTON, Delaware, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: MD. NPI: 1275066599. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry. Provider information is self-reported to CMS and updated monthly.
ANDREW SHYU, MD appears in the CMS NPPES registry as a Ophthalmology Physician provider holding MD credentials at 2500 GRUBB RD STE 234, WILMINGTON, DE, 19810, with a listed phone of (302) 475-6500. NPI 1275066599 was issued on 04/04/2017. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what SHYU 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 1,147 prescription claims written by this provider, covering 331 Medicare beneficiaries and totaling roughly $127K in drug spend, split 37% brand-name and 63% 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.
