Specialty board-certified rate — Psychiatric/Mental Health Nurse Practitioner estimate
Board certification through an ABMS or AOA member board signals voluntary post-licensure examination plus Maintenance of Certification cycles. CMS does not publish a per-provider board-certification field; the figure shown is the specialty-level estimated rate from ABMS / AOA reference data.
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).
KARI WILLIAMS, CRNP appears in the CMS NPPES registry as a Psychiatric/Mental Health Nurse Practitioner provider holding CRNP credentials at 1600 BROAD AVE, GULFPORT, MS, 39501, with a listed phone of (228) 213-5888. NPI 1932787421 was issued on 03/29/2021.

Medicare Part D records for calendar year 2023 show 1,719 prescription claims written by this provider, covering 134 Medicare beneficiaries and totaling roughly $802K in drug spend, split 12% brand-name and 88% generic by claim count. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy.
Psychiatric/Mental Health Nurse Practitioner is a mid-sized specialty nationwide, with 39,953 enrolled providers across 54 states and an average of 927 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.
