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).

INSU KONG, MD is a Gynecology Physician provider practicing in WESTERLY, Rhode Island, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: MD. NPI: 1346227188.

INSU KONG, MD appears in the CMS NPPES registry as a Gynecology Physician provider holding MD credentials at 31 CRESTVIEW DR, WESTERLY, RI, 02891, with a listed phone of (401) 596-9939. NPI 1346227188 was issued on 12/22/2005.

Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating.
