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).

CHRIS LANDON, M.D. is a Pediatric Allergy/Immunology Physician provider practicing in VENTURA, California, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D.. NPI: 1427118868. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry.

CHRIS LANDON, M.D. appears in the CMS NPPES registry as a Pediatric Allergy/Immunology Physician provider holding M.D. credentials at 300 HILLMONT AVE, BLDG 340 SUITE 302, VENTURA, CA, 93003, with a listed phone of (805) 652-6255. NPI 1427118868 was issued on 12/08/2006.

Medicare Part D records for calendar year 2023 show 23 prescription claims written by this provider, covering N/A Medicare beneficiaries and totaling roughly $3K in drug spend. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy.

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.
