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).

SILAS AUMELL is a Physician Assistant provider practicing in SEATTLE, Washington, according to the CMS National Plan and Provider Enumeration System (NPPES). NPI: 1922610443.

SILAS AUMELL appears in the CMS NPPES registry as a Physician Assistant provider at 4311 11TH AVE NE STE 200, SEATTLE, WA, 98105, with a listed phone of (206) 616-4001. NPI 1922610443 was issued on 08/17/2020.

Medicare Part D records for calendar year 2023 show 187 prescription claims written by this provider, covering 127 Medicare beneficiaries and totaling roughly $7K in drug spend, with an opioid prescribing rate of 16.0%.

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.
