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).

ANDREW AYARS, MD appears in the CMS NPPES registry as a Allergy & Immunology (Internal Medicine) Physician provider holding MD credentials at 3015 SQUALICUM PKWY STE 180, BELLINGHAM, WA, 98225, with a listed phone of (360) 733-5733. NPI 1336286608 was issued on 01/30/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what AYARS 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 824 prescription claims written by this provider, covering 156 Medicare beneficiaries and totaling roughly $1.5 million 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 93.0932/100 for the 2023 performance year (Quality 73.9573), compared with the national average of 83.1.

Allergy & Immunology (Internal Medicine) Physician is a narrow specialty nationwide, with 520 enrolled providers across 48 states and an average of 798 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.
