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).

CHRISTOPHER ADRIG, PA-C is a Physician Assistant provider practicing in SEATTLE, Washington, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: PA-C. NPI: 1184606089. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry.

CHRISTOPHER ADRIG, PA-C appears in the CMS NPPES registry as a Physician Assistant provider holding PA-C credentials at 201 16TH AVE E, SEATTLE, WA, 98112, with a listed phone of (206) 326-3000. NPI 1184606089 was issued on 11/16/2005.

Medicare Part D records for calendar year 2023 show 3,822 prescription claims written by this provider, covering 419 Medicare beneficiaries and totaling roughly $284K in drug spend, split 9% brand-name and 91% generic by claim count, with an opioid prescribing rate of 6.4%.

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.
