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).

GREGORY FORTNER, M.D. appears in the CMS NPPES registry as a Addiction Medicine (Psychiatry & Neurology) Physician provider holding M.D. credentials at 222S MAIN ST, REIDSVILLE, GA, 30453, with a listed phone of (912) 394-1002. NPI 1326240904 was issued on 06/05/2007.

Medicare Part D records for calendar year 2023 show 287 prescription claims written by this provider, covering 28 Medicare beneficiaries and totaling roughly $14K in drug spend, split 15% brand-name and 85% generic by claim count.

Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating.
