William Tanski, M.D. appears in the CMS NPPES registry as a Vascular Surgery Physician provider holding M.D. credentials at 250 PLEASANT ST, Concord, NH, 03301, with a listed phone of (603) 226-6122. NPI 1568564524 was issued on 09/01/2006.

Medicare Part D prescribing data is not currently published for this NPI, which typically means the provider either wrote fewer than 11 Part D claims in the most recent reporting year, does not participate in Medicare, or practices in a specialty that rarely prescribes outpatient drugs. Absence of prescribing data is not a quality signal, many Vascular Surgery Physician providers operate outside Part D entirely. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 69.4/100 for the 2023 performance year (Quality 55.6, Cost 42.4), compared with the national average of 83.1.

Vascular Surgery Physician is a narrow specialty nationwide, with 4,227 enrolled providers across 53 states and an average of 205 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
