Board certification
Not published by CMS
CMS does not publish a per-provider board-certification field in NPPES. PlainDoctor does not have a reliable per-specialty certification rate to show for Dentist. Verify directly:
How MIPS and board certification work
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).
Lionel Ardoin, DDS appears in the CMS NPPES registry as a Dentist provider holding DDS credentials at 1520 EAST MAIN STREET, Ville Platte, LA, 70586, with a listed phone of (337) 363-6590. NPI 1003919184 was issued on 09/06/2006.
Medicare Part D records for calendar year 2023 show 915 prescription claims written by this provider, covering 300 Medicare beneficiaries and totaling roughly $4K in drug spend, with an opioid prescribing rate of 17.2%.
Dentist is a high-volume specialty nationwide, with 93,793 enrolled providers across 56 states and an average of 87 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.
