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).

SHERI CHACON, PHYSICIAN ASSISTANT appears in the CMS NPPES registry as a Surgical Physician Assistant provider holding PHYSICIAN ASSISTANT credentials at 11435 W BUCKEYE RD STE A106, AVONDALE, AZ, 85323, with a listed phone of (480) 677-8282. NPI 1497925424 was issued on 03/05/2008.

Medicare Part D records for calendar year 2023 show 2,758 prescription claims written by this provider, covering 245 Medicare beneficiaries and totaling roughly $382K in drug spend, split 19% brand-name and 81% generic by claim count, with an opioid prescribing rate of 2.4%. 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.

Surgical Physician Assistant is a mid-sized specialty nationwide, with 16,119 enrolled providers across 54 states and an average of 316 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.
