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).

ARASH AMINIAN, M.D. appears in the CMS NPPES registry as a Orthopaedic Foot and Ankle Surgery Physician provider holding M.D. credentials at 24331 EL TORO RD STE 200, LAGUNA WOODS, CA, 92637, with a listed phone of (949) 586-3200.

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