JOSEPH CARUSO, M.D. appears in the CMS NPPES registry as a Medical Toxicology (Emergency Medicine) Physician provider holding M.D. credentials at 4630 VISTULA RD, MISHAWAKA, IN, 46544, with a listed phone of (574) 647-1900. NPI 1598763203 was issued on 07/07/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CARUSO 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 7,136 prescription claims written by this provider, covering 595 Medicare beneficiaries and totaling roughly $498K in drug spend, split 9% brand-name and 91% generic by claim count, with an opioid prescribing rate of 6.2%. 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.

Medical Toxicology (Emergency Medicine) Physician is a narrow specialty nationwide, with 226 enrolled providers across 39 states and an average of 329 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.
