MIPS final score (Interventional Cardiology Physician) — 100/100 vs national avg 83.1

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).

JOHN CANALES, M.D. is a Interventional Cardiology Physician provider practicing in LIVE OAK, Texas, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D.. NPI: 1548377088. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry.

JOHN CANALES, M.D. appears in the CMS NPPES registry as a Interventional Cardiology Physician provider holding M.D. credentials at 12709 TOEPPERWEIN RD, LIVE OAK, TX, 78233, with a listed phone of (210) 967-0096. NPI 1548377088 was issued on 08/23/2006.

Interventional Cardiology Physician is a narrow specialty nationwide, with 3,382 enrolled providers across 53 states and an average of 2,984 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.
