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).

CHET THARPE, M.D. is a Allergy Physician provider practicing in VENICE, California, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D.. NPI: 1053541581. 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.

CHET THARPE, M.D. appears in the CMS NPPES registry as a Allergy Physician provider holding M.D. credentials at 320 LINCOLN BLVD #100, VENICE, CA, 90291, with a listed phone of (310) 697-8126. NPI 1053541581 was issued on 07/17/2009.

Medicare Part D records for calendar year 2023 show 671 prescription claims written by this provider, covering 128 Medicare beneficiaries and totaling roughly $1.2 million in drug spend, split 77% brand-name and 23% 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.
