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).

ARSHAD ASGHAR, MD is a Nephrology Physician provider practicing in IRVING, Texas, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: MD. NPI: 1255541488. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry. Provider information is self-reported to CMS and updated monthly.

ARSHAD ASGHAR, MD appears in the CMS NPPES registry as a Nephrology Physician provider holding MD credentials at 2005 W PARK DR STE 200, IRVING, TX, 75061, with a listed phone of (214) 358-2300. NPI 1255541488 was issued on 05/23/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ASGHAR most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D records for calendar year 2023 show 457 prescription claims written by this provider, covering 95 Medicare beneficiaries and totaling roughly $47K in drug spend, split 7% brand-name and 93% 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.
