TIMOTHY DAO, M.D. appears in the CMS NPPES registry as a Nuclear Cardiology Physician provider holding M.D. credentials at 3801 W 15TH ST, PLANO, TX, 75075, with a listed phone of (972) 985-8838. NPI 1407029689 was issued on 04/08/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what DAO 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 3,505 prescription claims written by this provider, covering 472 Medicare beneficiaries and totaling roughly $583K 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 86.7849/100 for the 2023 performance year (Quality 82.8447, Cost 64.1493), compared with the national average of 83.1.

Nuclear Cardiology Physician is a narrow specialty nationwide, with 374 enrolled providers across 37 states and an average of 4,019 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.
