MIPS final score (Nephrology Physician) — 75/100 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).

MELODY DUMLAO, M.D is a Nephrology Physician provider practicing in PORTERVILLE, California, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D. NPI: 1316938178. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry.

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