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 Oncology Registered Nurse. 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).
John Curfman appears in the CMS NPPES registry as an Oncology Registered Nurse provider at 460 W 10TH AVE, Columbus, OH, 43210, with a listed phone of (614) 366-7729. NPI 1780039412 was issued on 05/02/2016.
Medicare Part D records for calendar year 2023 show 166 prescription claims written by this provider, covering 74 Medicare beneficiaries and totaling roughly $6K in drug spend, split 8% brand-name and 92% generic by claim count.
Oncology Registered Nurse is a narrow specialty nationwide, with 883 enrolled providers across 50 states and an average of 555 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.

- Confirm the NPI record is current in the official CMS registry, providers update their own NPPES details, and moves can lag. Verify this NPI
- Check the active license and any disciplinary history with the Ohio medical board, federal registration is not a license check. Credential verification guide
- Weigh a second option: compare this provider with a nearby Oncology Registered Nurse peer on Medicare volume and prescribing patterns. Compare providers
