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).

FOTINI CHALKIAS, M.D. is a Nuclear Cardiology Physician provider practicing in AUSTIN, Texas, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D.. NPI: 1518065317. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry.

FOTINI CHALKIAS, M.D. appears in the CMS NPPES registry as a Nuclear Cardiology Physician provider holding M.D. credentials at 2608 BROCKTON DR, AUSTIN, TX, 78758, with a listed phone of (512) 654-4050. NPI 1518065317 was issued on 09/20/2006.

Medicare Part D records for calendar year 2023 show 12,811 prescription claims written by this provider, covering 1,203 Medicare beneficiaries and totaling roughly $1.9 million in drug spend, split 15% brand-name and 85% generic by claim count. 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.
