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 Obstetrics & Gynecology Physician. 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).
Brent Davidson, M.D. appears in the CMS NPPES registry as an Obstetrics & Gynecology Physician provider holding M.D. credentials at 2799 W GRAND BLVD, Detroit, MI, 48202, with a listed phone of (313) 916-2600. NPI 1336216480 was issued on 11/30/2006.
Medicare Part D records for calendar year 2023 show 487 prescription claims written by this provider, covering 157 Medicare beneficiaries and totaling roughly $82K in drug spend, split 41% brand-name and 59% generic by claim count.
Obstetrics & Gynecology Physician is a mid-sized specialty nationwide, with 44,326 enrolled providers across 56 states and an average of 179 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.
