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).

ANGELA BARNES, MD is a Gastroenterology Physician provider practicing in RIO RANCHO, New Mexico, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: MD. NPI: 1487218434. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry.

ANGELA BARNES, MD appears in the CMS NPPES registry as a Gastroenterology Physician provider holding MD credentials at 2400 UNSER BLVD SE, RIO RANCHO, NM, 87124, with a listed phone of (661) 212-3925. NPI 1487218434 was issued on 04/25/2019.

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.
