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).

GUILHERME ATTIZZANI is a Cardiovascular Disease Physician provider practicing in CLEVELAND, Ohio, according to the CMS National Plan and Provider Enumeration System (NPPES). NPI: 1144621889.

GUILHERME ATTIZZANI appears in the CMS NPPES registry as a Cardiovascular Disease Physician provider at 11100 EUCLID AVE, CLEVELAND, OH, 44106, with a listed phone of (216) 844-3800. NPI 1144621889 was issued on 09/12/2014. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ATTIZZANI 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 52 prescription claims written by this provider, covering 27 Medicare beneficiaries and totaling roughly $153 in drug spend. 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.

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.
