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).

DIONYSIOS VERONIKIS, MD appears in the CMS NPPES registry as a Urogynecology and Reconstructive Pelvic Surgery (Obstetrics & Gynecology) Physician provider holding MD credentials at 621 S NEW BALLAS RD, SAINT LOUIS, MO, 63141, with a listed phone of (314) 251-6753. NPI 1629047626 was issued on 03/14/2006.

Medicare Part D records for calendar year 2023 show 755 prescription claims written by this provider, covering 284 Medicare beneficiaries and totaling roughly $89K in drug spend, split 16% brand-name and 84% generic by claim count, with an opioid prescribing rate of 19.6%.

Urogynecology and Reconstructive Pelvic Surgery (Obstetrics & Gynecology) Physician is a narrow specialty nationwide, with 568 enrolled providers across 49 states and an average of 611 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.
