STEPHAN EILER, D.D.S. appears in the CMS NPPES registry as a General Practice Dentistry provider holding D.D.S. credentials at 644 W OSHKOSH ST, RIPON, WI, 54971, with a listed phone of (920) 748-6122. NPI 1184717258 was issued on 10/02/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what EILER 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 29 prescription claims written by this provider, covering 20 Medicare beneficiaries and totaling roughly $325 in drug spend. 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.

General Practice Dentistry is a high-volume specialty nationwide, with 121,627 enrolled providers across 56 states and an average of 82 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. 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.
