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).

DENNIS THOMPSON, D.O. is a Adult Medicine Physician provider practicing in CLEVELAND, Tennessee, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: D.O.. NPI: 1326151655. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry.

DENNIS THOMPSON, D.O. appears in the CMS NPPES registry as a Adult Medicine Physician provider holding D.O. credentials at 2700 WESTSIDE DR NW, CLEVELAND, TN, 37312, with a listed phone of (423) 472-1511. NPI 1326151655 was issued on 08/17/2006.

Medicare Part D records for calendar year 2023 show 9,692 prescription claims written by this provider, covering 487 Medicare beneficiaries and totaling roughly $1.1 million in drug spend, split 10% brand-name and 90% generic by claim count, with an opioid prescribing rate of 1.2%.

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.
