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).

MARGRETH BRONTOLI, MD is a Ophthalmology Physician provider practicing in LONG BEACH, New York, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: MD.

MARGRETH BRONTOLI, MD appears in the CMS NPPES registry as a Ophthalmology Physician provider holding MD credentials at 202 W PARK AVE, LONG BEACH, NY, 11561, with a listed phone of (516) 431-1101. NPI 1235142639 was issued on 08/15/2006.

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.
