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).

SAMIR NEIMAT, M.D. is a Vascular Surgery Physician provider practicing in CHEVY CHASE, Maryland, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D..

SAMIR NEIMAT, M.D. appears in the CMS NPPES registry as a Vascular Surgery Physician provider holding M.D. credentials at 5454 WISCONSIN AVE, CHEVY CHASE, MD, 20815, with a listed phone of (301) 270-1006. NPI 1730132929 was issued on 05/18/2006.

Medicare Part D records for calendar year 2023 show 54 prescription claims written by this provider, covering N/A Medicare beneficiaries and totaling roughly $9K in drug spend, split 30% brand-name and 70% 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.
