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).

GREGORY DORILUS, MD appears in the CMS NPPES registry as a Emergency Medicine Physician provider holding MD credentials at 2651 E DISCOVERY PKWY, BLOOMINGTON, IN, 47408, with a listed phone of (812) 353-9515. NPI 1619403292 was issued on 05/02/2017.

Medicare Part D records for calendar year 2023 show 287 prescription claims written by this provider, covering 209 Medicare beneficiaries and totaling roughly $5K in drug spend, with an opioid prescribing rate of 10.8%.

Emergency Medicine Physician is a high-volume specialty nationwide, with 64,398 enrolled providers across 56 states and an average of 352 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.
