FRANK TUNG, M.D. appears in the CMS NPPES registry as a Adult Congenital Heart Disease Physician provider holding M.D. credentials at 139 CENTRE ST, NEW YORK, NY, 10013, with a listed phone of (212) 334-3507. NPI 1740243864 was issued on 04/10/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what TUNG 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 11,340 prescription claims written by this provider, covering 1,358 Medicare beneficiaries and totaling roughly $2.7 million in drug spend, split 25% brand-name and 75% 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.

Adult Congenital Heart Disease Physician is a narrow specialty nationwide, with 104 enrolled providers across 31 states and an average of 1,930 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.
