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).

RANDA RAZZOUK, MD appears in the CMS NPPES registry as a Pediatric Nephrology Physician provider holding MD credentials at 1500 COOPER ST, FORT WORTH, TX, 76104, with a listed phone of (682) 885-4260. NPI 1558511071 was issued on 09/19/2008.
