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 Nurse Practitioner. 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).
Ngozi Obiora, FNP appears in the CMS NPPES registry as a Nurse Practitioner provider holding FNP credentials at 5000 W CHAMBERS ST, Milwaukee, WI, 53210, with a listed phone of (414) 874-1171. NPI 1417918939 was issued on 04/01/2006.
Medicare Part D records for calendar year 2023 show 2,463 prescription claims written by this provider, covering 207 Medicare beneficiaries and totaling roughly $476K in drug spend, split 7% brand-name and 93% generic by claim count.

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.
