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).

JAAFAR AL-DAHWI, MD is a Hospitalist Physician provider practicing in SAN DIEGO, California, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: MD.

JAAFAR AL-DAHWI, MD appears in the CMS NPPES registry as a Hospitalist Physician provider holding MD credentials at 3880 MURPHY CANYON RD STE 120, SAN DIEGO, CA, 92123, with a listed phone of (858) 268-1111. NPI 1639551435 was issued on 06/29/2015.

Medicare Part D records for calendar year 2023 show 2,731 prescription claims written by this provider, covering 326 Medicare beneficiaries and totaling roughly $358K in drug spend, split 12% brand-name and 88% generic by claim count, with an opioid prescribing rate of 2.8%.

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.
