Boyd Erdman, M.D. appears in the CMS NPPES registry as a Phlebology Physician provider holding M.D. credentials at 114 E MAIN ST STE 115, Waunakee, WI, 53597, with a listed phone of (608) 831-7003. NPI 1508989716 was issued on 04/10/2007.

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 Phlebology Physician providers operate outside Part D entirely.

Phlebology Physician is a narrow specialty nationwide, with 275 enrolled providers across 43 states and an average of 463 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
