Van-Khue Ton, MD, PHD appears in the CMS NPPES registry as a Advanced Heart Failure and Transplant Cardiology Physician provider holding MD, PHD credentials at MASSACHUSETTS GENERAL HOSPITAL, Boston, MA, 02114, with a listed phone of (617) 726-2862. NPI 1497982938 was issued on 06/11/2009. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Ton 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 1,419 prescription claims written by this provider, covering 175 Medicare beneficiaries and totaling roughly $2.3 million in drug spend, split 44% brand-name and 56% generic by claim count, with an opioid prescribing rate of 0.8%. 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.

Advanced Heart Failure and Transplant Cardiology Physician is a narrow specialty nationwide, with 510 enrolled providers across 48 states and an average of 1,762 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.

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.
