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 Legal Medicine. 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).
Peggy Richardson, M.D. appears in the CMS NPPES registry as a Legal Medicine provider holding M.D. credentials at 20755 GREENFIELD RD, Southfield, MI, 48075, with a listed phone of (248) 557-7546. NPI 1013099548 was issued on 10/20/2006.
Medicare Part D records for calendar year 2023 show 329 prescription claims written by this provider, covering N/A Medicare beneficiaries and totaling roughly $44K in drug spend, split 10% brand-name and 87% generic by claim count, with an opioid prescribing rate of 7.9%.
Legal Medicine is a narrow specialty nationwide, with 1,065 enrolled providers across 51 states and an average of 2,821 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.
