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).

ANDREA AGCAOILI, D.O. is a Family Medicine Physician provider practicing in WALNUT CREEK, California, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: D.O.. NPI: 1265775035. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry.

ANDREA AGCAOILI, D.O. appears in the CMS NPPES registry as a Family Medicine Physician provider holding D.O. credentials at 1450 TREAT BLVD, WALNUT CREEK, CA, 94597, with a listed phone of (925) 296-9720. NPI 1265775035 was issued on 03/31/2013.

Medicare Part D records for calendar year 2023 show 3,216 prescription claims written by this provider, covering 369 Medicare beneficiaries and totaling roughly $198K in drug spend, split 7% brand-name and 93% generic by claim count, with an opioid prescribing rate of 2.9%.

Family Medicine Physician is a high-volume specialty nationwide, with 147,640 enrolled providers across 56 states and an average of 3,418 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.
