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).

MICHAEL BROWN, MD is a Specialist provider practicing in ATLANTA, Georgia, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: MD. NPI: 1649286782.

MICHAEL BROWN, MD appears in the CMS NPPES registry as a Specialist provider holding MD credentials at 2140 PEACHTREE RD NW, ATLANTA, GA, 30309, with a listed phone of (404) 231-4431. NPI 1649286782 was issued on 07/31/2006.

Medicare Part D records for calendar year 2023 show 3,023 prescription claims written by this provider, covering 148 Medicare beneficiaries and totaling roughly $4.8 million in drug spend, split 51% brand-name and 49% generic by claim count, with an opioid prescribing rate of 1.0%.

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.
