MICHAEL CHARDACK, MD appears in the CMS NPPES registry as a Orthopaedic Trauma Physician provider holding MD credentials at 617 W CLAIREMONT AVE, EAU CLAIRE, WI, 54701, with a listed phone of (920) 496-4700. NPI 1679520944 was issued on 05/30/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CHARDACK 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 26 prescription claims written by this provider, covering 17 Medicare beneficiaries and totaling roughly $978 in drug spend, with an opioid prescribing rate of 50.0%. 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.

Orthopaedic Trauma Physician is a narrow specialty nationwide, with 715 enrolled providers across 51 states and an average of 160 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.
