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).

TIMOTHY POWELL, MD is a Epilepsy Physician provider practicing in SPOKANE, Washington, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: MD. NPI: 1982697090. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry. Provider information is self-reported to CMS and updated monthly.

TIMOTHY POWELL, MD appears in the CMS NPPES registry as a Epilepsy Physician provider holding MD credentials at 105 W 8TH AVE, SPOKANE, WA, 99204, with a listed phone of (509) 474-6650. NPI 1982697090 was issued on 08/24/2005.

Medicare Part D records for calendar year 2023 show 5,239 prescription claims written by this provider, covering 590 Medicare beneficiaries and totaling roughly $1.6 million in drug spend, split 12% brand-name and 88% generic by claim count.

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.
