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).

PATRICK CORCORAN, M.D. is a Interventional Cardiology Physician provider practicing in BLOOMFIELD, Connecticut, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D.. NPI: 1144298415. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry.

PATRICK CORCORAN, M.D. appears in the CMS NPPES registry as a Interventional Cardiology Physician provider holding M.D. credentials at 711 COTTAGE GROVE RD, BLOOMFIELD, CT, 06002, with a listed phone of (860) 242-8756. NPI 1144298415 was issued on 03/10/2006.

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.
