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).

JOSEPH DIZON, MD is a Allergy Physician provider practicing in LOS ANGELES, California, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: MD. NPI: 1750440343. 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.

JOSEPH DIZON, MD appears in the CMS NPPES registry as a Allergy Physician provider holding MD credentials at 6041 CADILLAC AVE, LOS ANGELES, CA, 90034, with a listed phone of (323) 857-2000. NPI 1750440343 was issued on 12/08/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what DIZON 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 1,180 prescription claims written by this provider, covering 266 Medicare beneficiaries and totaling roughly $393K in drug spend, split 34% brand-name and 66% generic by claim count.

Allergy Physician is a narrow specialty nationwide, with 1,019 enrolled providers across 49 states and an average of 755 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. 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.
