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).

ERIC DOMINGUEZ, MD appears in the CMS NPPES registry as a Pain Medicine (Anesthesiology) Physician provider holding MD credentials at 795 MIDDLE ST, FALL RIVER, MA, 02721, with a listed phone of (508) 235-5258. NPI 1265427702 was issued on 09/12/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what DOMINGUEZ most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D records for calendar year 2023 show 4,288 prescription claims written by this provider, covering 891 Medicare beneficiaries and totaling roughly $312K in drug spend, split 9% brand-name and 91% generic by claim count, with an opioid prescribing rate of 59.5%. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy.

Pain Medicine (Anesthesiology) Physician is a narrow specialty nationwide, with 4,020 enrolled providers across 53 states and an average of 1,657 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.
