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).

AHMAD ABDUL KARIM, M.D appears in the CMS NPPES registry as a Clinical Cardiac Electrophysiology Physician provider holding M.D credentials at 301 MADISON ST, JOLIET, IL, 60435, with a listed phone of (815) 740-1900.
