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).

AYOOLA GOMIH, M.D. appears in the CMS NPPES registry as a Specialist provider holding M.D. credentials at 398 W 80TH PL, MERRILLVILLE, IN, 46410, with a listed phone of (219) 791-0615. NPI 1831117522 was issued on 07/18/2006.

Medicare Part D records for calendar year 2023 show 1,251 prescription claims written by this provider, covering 335 Medicare beneficiaries and totaling roughly $1.0 million in drug spend.

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.
