Evan Klein, M.D. appears in the CMS NPPES registry as a Advanced Heart Failure and Transplant Cardiology Physician provider holding M.D. credentials at 600 HIGHLAND AVE, Madison, WI, 53792, with a listed phone of (608) 263-1690. NPI 1245677061 was issued on 06/03/2013. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Klein 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 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 Advanced Heart Failure and Transplant Cardiology Physician providers operate outside Part D entirely.

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.
