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).

FOLASADE ONASANYA, CRNP appears in the CMS NPPES registry as a Primary Care Nurse Practitioner provider holding CRNP credentials at 3312 CROYDON RD, BALTIMORE, MD, 21207, with a listed phone of (443) 565-2408. NPI 1598364192 was issued on 10/23/2020.

Medicare Part D records for calendar year 2023 show 101 prescription claims written by this provider, covering N/A Medicare beneficiaries and totaling roughly $17K in drug spend, split 27% brand-name and 73% generic by claim count.

Primary Care Nurse Practitioner is a mid-sized specialty nationwide, with 10,138 enrolled providers across 54 states and an average of 1,363 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.
