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).

ALBERTO BESSUDO, M.D. is a Internal Medicine Physician provider practicing in ENCINITAS, California, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D..

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