CONNIE HSU, MD appears in the CMS NPPES registry as a Vascular & Interventional Radiology Physician provider holding MD credentials at 12554 RIATA VISTA CIR, AUSTIN, TX, 78727, with a listed phone of (512) 795-5100. NPI 1801890603 was issued on 06/09/2005.

Medicare Part D records for calendar year 2023 show 78 prescription claims written by this provider, covering 24 Medicare beneficiaries and totaling roughly $469 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 83.1381/100 for the 2023 performance year (Quality 80.1625), compared with the national average of 83.1.

Vascular & Interventional Radiology Physician is a narrow specialty nationwide, with 2,981 enrolled providers across 53 states and an average of 72 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.
