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).

BRUCE MACKAY, MD is a Vascular Neurology Physician provider practicing in BELLINGHAM, Washington, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: MD. NPI: 1902837180. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry.

BRUCE MACKAY, MD appears in the CMS NPPES registry as a Vascular Neurology Physician provider holding MD credentials at 710 BIRCHWOOD AVE, BELLINGHAM, WA, 98225, with a listed phone of (360) 788-6870. NPI 1902837180 was issued on 07/05/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MACKAY 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 2,140 prescription claims written by this provider, covering 274 Medicare beneficiaries and totaling roughly $773K in drug spend, split 10% brand-name and 90% generic by claim count.

Vascular Neurology Physician is a narrow specialty nationwide, with 555 enrolled providers across 47 states and an average of 378 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.
