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).

KENNETH GRAFFEO, M.D. is a Specialist provider practicing in DELAWARE, Ohio, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D.. NPI: 1134217862. 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.

KENNETH GRAFFEO, M.D. appears in the CMS NPPES registry as a Specialist provider holding M.D. credentials at 551 W CENTRAL AVE STE 103, DELAWARE, OH, 43015, with a listed phone of (740) 363-1473. NPI 1134217862 was issued on 10/10/2006.

Medicare Part D records for calendar year 2023 show 332 prescription claims written by this provider, covering 202 Medicare beneficiaries and totaling roughly $10K in drug spend, split 15% brand-name and 85% generic by claim count, with an opioid prescribing rate of 16.0%.

Specialist is a high-volume specialty nationwide, with 69,658 enrolled providers across 55 states and an average of 1,474 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.
