KEVIN PARCIAK, MD appears in the CMS NPPES registry as a Medical Toxicology (Emergency Medicine) Physician provider holding MD credentials at N2950 STATE ROAD 67, LAKE GENEVA, WI, 53147, with a listed phone of (262) 245-0535. NPI 1699835181 was issued on 12/12/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what PARCIAK 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 249 prescription claims written by this provider, covering 152 Medicare beneficiaries and totaling roughly $3K in drug spend, with an opioid prescribing rate of 16.1%. 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. 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.
