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).

CARL ASKREN, M.D. appears in the CMS NPPES registry as a Plastic Surgery Physician provider holding M.D. credentials at 1351 E SPRUCE AVE, FRESNO, CA, 93720, with a listed phone of (559) 432-3303. NPI 1134188097 was issued on 03/20/2006.

Medicare Part D records for calendar year 2023 show 170 prescription claims written by this provider, covering 41 Medicare beneficiaries and totaling roughly $2K in drug spend, with an opioid prescribing rate of 22.9%.

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.
