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).

ANNIE AHN is a Otolaryngology Physician provider practicing in RENTON, Washington, according to the CMS National Plan and Provider Enumeration System (NPPES). NPI: 1598182990.

ANNIE AHN appears in the CMS NPPES registry as a Otolaryngology Physician provider at 4033 TALBOT RD S STE 540, RENTON, WA, 98055, with a listed phone of (425) 690-3602. NPI 1598182990 was issued on 03/24/2014.

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.
