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).

ROBERT DIMITRIOU, M.D. is a Urology Physician provider practicing in EAST LANSING, Michigan, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D..

ROBERT DIMITRIOU, M.D. appears in the CMS NPPES registry as a Urology Physician provider holding M.D. credentials at 1625 RAMBLEWOOD DR STE 1, EAST LANSING, MI, 48823, with a listed phone of (517) 324-3700. NPI 1932163763 was issued on 04/17/2006.

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.
