THOMAS KUPFERER, D.O. appears in the CMS NPPES registry as a Emergency Medicine Physician provider holding D.O. credentials at 628 N 14TH ST, MURPHYSBORO, IL, 62966, with a listed phone of (618) 687-2353. NPI 1437147089 was issued on 10/07/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what KUPFERER 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 5,682 prescription claims written by this provider, covering 283 Medicare beneficiaries and totaling roughly $498K in drug spend, split 13% brand-name and 87% generic by claim count, with an opioid prescribing rate of 9.0%. 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.

Emergency Medicine Physician is a high-volume specialty nationwide, with 64,398 enrolled providers across 56 states and an average of 352 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.
