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 GLASS, MD appears in the CMS NPPES registry as a Obstetrics & Gynecology Physician provider holding MD credentials at 3815 S BOULEVARD ST, EDMOND, OK, 73013, with a listed phone of (405) 341-9996. NPI 1750362836 was issued on 11/07/2005.

Medicare Part D records for calendar year 2023 show 180 prescription claims written by this provider, covering 56 Medicare beneficiaries and totaling roughly $18K in drug spend, split 12% brand-name and 88% generic by claim count.

Obstetrics & Gynecology Physician is a mid-sized specialty nationwide, with 44,313 enrolled providers across 56 states and an average of 179 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.
