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).

GEORGE KUBAC, M.D. is a Interventional Cardiology Physician provider practicing in KLAMATH FALLS, Oregon, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D.. NPI: 1114081700. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry.

GEORGE KUBAC, M.D. appears in the CMS NPPES registry as a Interventional Cardiology Physician provider holding M.D. credentials at 3001 DAGGETT AVE STE 101, KLAMATH FALLS, OR, 97601, with a listed phone of (541) 884-6233. NPI 1114081700 was issued on 12/20/2006.

Medicare Part D records for calendar year 2023 show 4,321 prescription claims written by this provider, covering 625 Medicare beneficiaries and totaling roughly $635K in drug spend, split 13% brand-name and 87% generic by claim count, with an opioid prescribing rate of 0.5%.

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.
