VASUTAKARN CHONGTHAMMAKUN, MD PHD appears in the CMS NPPES registry as a Cardiovascular Disease Physician provider holding MD PHD credentials at 2001 CRYSTAL SPRING AVE SW STE 203, ROANOKE, VA, 24014, with a listed phone of (540) 982-8204. NPI 1932464732 was issued on 07/08/2012. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CHONGTHAMMAKUN 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 264 prescription claims written by this provider, covering 60 Medicare beneficiaries and totaling roughly $38K in drug spend, split 12% brand-name and 88% 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.

Cardiovascular Disease Physician is a mid-sized specialty nationwide, with 24,795 enrolled providers across 54 states and an average of 3,033 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.
