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 Pharmacist. 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).
Alyson Leonard appears in the CMS NPPES registry as a Oncology Pharmacist provider at 1236 HUFFMAN MILL RD STE 120, Burlington, NC, 27215, with a listed phone of (336) 586-3756. NPI 1417546532 was issued on 01/13/2021.
Medicare Part D records for calendar year 2023 show 219 prescription claims written by this provider, covering 45 Medicare beneficiaries and totaling roughly $2.1 million in drug spend, split 62% brand-name and 38% generic by claim count.
Oncology Pharmacist is a narrow specialty nationwide, with 1,699 enrolled providers across 50 states and an average of 160 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.
