Authorities in northern Indiana say a Chicago physician set up shop in a private home, offering intravenous “wellness” treatments that wound up getting him charged with multiple felonies.
Michael Close, 62, was arrested after Warsaw police say he administered IV treatments from a residence and kept medical supplies in his car. Charging documents list two counts of practicing medicine without a license, one count of unlawful possession or use of a legend drug, and one count of battery. Officers say they found syringes and vials in his vehicle and that Close admitted injecting a woman, telling police the shot was vitamin B-12.
According to court records, the investigation started when authorities received a letter raising concerns about a woman’s safety and alleging she was receiving IV NAD treatments inside a Warsaw home. Investigators later visited the address and recovered items from Close’s vehicle. As reported by WNDU, the paperwork states Close acknowledged giving the injection and that officers discovered multiple prescription drugs in the car.
On his practice website, Close describes himself as a “neurologic specialist” who “delivers advanced restorative medicine through personalized NAD+ therapies,” listing an office at 4906 N. Western Ave. in Chicago’s Lincoln Square neighborhood. Those details were reviewed by NBC Chicago, which also reports that the Illinois Department of Financial and Professional Regulation suspended his license effective March 3, 2026, for at least 12 months.
License history and past discipline
Close’s history with Illinois regulators stretches back more than a decade. Enforcement documents from 2013 describe a summary suspension tied to a failure to account for more than 21,000 dosage units of controlled substances. Those earlier disciplinary actions are listed in enforcement records maintained by the Illinois Department of Financial and Professional Regulation.
What NAD+ infusions involve
NAD+ infusions, marketed by some clinics as restorative or anti-aging treatments, fall into a broader category of IV “wellness” services that health officials say still require real medical oversight and proper patient evaluation. Court filings in the Warsaw case describe the injections as IV NAD treatments, and local coverage has noted that such services are typically expected to be prescribed and administered under the supervision of a licensed practitioner, according to WNDU.
Legal context
Under Indiana law, knowingly practicing medicine without a valid state license is a Class C felony, and statutes allow prosecutors or the attorney general to seek injunctions or criminal charges in those cases, according to Justia. Any penalties and outcomes for Close will be decided in Kosciusko County court and through any related actions by Indiana regulators.
Warsaw police say the investigation is still active, with the possibility that additional suspects could be identified as they sift through evidence and charging documents. As reported by NBC Chicago, the case remains pending while local authorities and prosecutors determine their next moves.
