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).

RAYZE SIMONSON, MD is a Obstetrics Physician provider practicing in NEW YORK, New York, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: MD. NPI: 1033170592. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry. Provider information is self-reported to CMS and updated monthly.

RAYZE SIMONSON, MD appears in the CMS NPPES registry as a Obstetrics Physician provider holding MD credentials at 50 W 77TH ST, NEW YORK, NY, 10024, with a listed phone of (212) 579-6000. NPI 1033170592 was issued on 03/31/2006.

Medicare Part D records for calendar year 2023 show 157 prescription claims written by this provider, covering 51 Medicare beneficiaries and totaling roughly $17K in drug spend, split 9% brand-name and 91% generic by claim count.

Obstetrics Physician is a narrow specialty nationwide, with 1,402 enrolled providers across 54 states and an average of 319 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. 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.
