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).

WHITNEY JOHNSON, APRN appears in the CMS NPPES registry as a Acute Care Nurse Practitioner provider holding APRN credentials at 805 PAMPLICO HWY STE B300, FLORENCE, SC, 29505, with a listed phone of (843) 673-7529. NPI 1134890064 was issued on 09/21/2021.

Medicare Part D records for calendar year 2023 show 584 prescription claims written by this provider, covering 151 Medicare beneficiaries and totaling roughly $255K in drug spend, split 59% brand-name and 41% generic by claim count.

Acute Care Nurse Practitioner is a mid-sized specialty nationwide, with 24,583 enrolled providers across 53 states and an average of 576 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.
