DAVID SLIWOSKI, MD appears in the CMS NPPES registry as a Pain Medicine (Anesthesiology) Physician provider holding MD credentials at W180N11070 RIVER LN, GERMANTOWN, WI, 53022, with a listed phone of (262) 532-9700. NPI 1184923468 was issued on 03/25/2011. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what SLIWOSKI 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 2,280 prescription claims written by this provider, covering 437 Medicare beneficiaries and totaling roughly $43K in drug spend, with an opioid prescribing rate of 29.7%. 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.

Pain Medicine (Anesthesiology) Physician is a narrow specialty nationwide, with 4,020 enrolled providers across 53 states and an average of 1,657 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.
