Board certification
Not published by CMS
CMS does not publish a per-provider board-certification field in NPPES. PlainDoctor does not have a reliable per-specialty certification rate to show for Pediatric Nephrology Physician. Verify directly:
How MIPS and board certification work
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.
Medicare Part D records for calendar year 2023 show 358 prescription claims written by this provider, covering 18 Medicare beneficiaries and totaling roughly $844K in drug spend, split 12% brand-name and 88% generic by claim count.

Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist, always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
