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).

MUHAMMAD AHMAD, M.D. is a Transplant Hepatology Physician provider practicing in ALEXANDRIA, Louisiana, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D.. NPI: 1891045183. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry.

MUHAMMAD AHMAD, M.D. appears in the CMS NPPES registry as a Transplant Hepatology Physician provider holding M.D. credentials at 201 4TH ST, ALEXANDRIA, LA, 71301, with a listed phone of (318) 625-4149. NPI 1891045183 was issued on 09/13/2012. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what AHMAD 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 369 prescription claims written by this provider, covering 194 Medicare beneficiaries and totaling roughly $171K in drug spend, split 38% brand-name and 62% 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.
