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).

ERWIN PEYTON, MD is a Adult Medicine Physician provider practicing in GADSDEN, Alabama, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: MD. NPI: 1669563649.

ERWIN PEYTON, MD appears in the CMS NPPES registry as a Adult Medicine Physician provider holding MD credentials at 601 S 4TH ST, GADSDEN, AL, 35901, with a listed phone of (256) 547-6969. NPI 1669563649 was issued on 09/27/2006.

Medicare Part D records for calendar year 2023 show 2,447 prescription claims written by this provider, covering 112 Medicare beneficiaries and totaling roughly $371K in drug spend, split 12% brand-name and 88% generic by claim count, with an opioid prescribing rate of 2.0%.

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.
