The Office of the Inspector General (OIG) protects Wisconsin taxpayers by tracking and preventing fraud, waste, and abuse in public assistance programs administered by DHS, like Medicaid, FoodShare, and Family Care. At the same time, OIG's internal audits protect the accountability of DHS programs and operations.

Established in October 2011, OIG consolidates all program integrity, audit, and fraud investigation activities into one office. Since its beginning, it has saved taxpayers millions of dollars. Staff works closely with other state and local partners to identify misuses of public assistance funds, and where appropriate, forwards fraud cases to federal, state, and local officials for prosecution.

Misuse of public funds affects each person who lives in Wisconsin. We encourage everyone to report suspected fraud, waste, or abuse. Call the fraud hotline at 877-865-3432 or use the fraud reporting website. You may remain anonymous, if you wish.

Programs and Services Within OIG

The Medical and Program Audit Review sections focus on preventing, detecting, and investigating provider fraud, waste, and abuse in Wisconsin’s Medicaid program.

The Fraud Investigation, Recovery, and Enforcement section investigates possible recipient fraud in DHS programs like BadgerCare Plus, Medicaid, and FoodShare, as well as retailer fraud in the WIC program.

Internal auditors objectively investigate and evaluate DHS programs and processes to improve operations, reduce risk, increase efficiency, and provide oversight.

The Data Analytics section collects and analyzes data used by OIG in audits and investigations, and reports monthly statistical results.

OIG staffers work closely with our partners, helping with verifications, collections, and overpayments. They also provide technical auditing and accounting guidance to providers.

OIG issues information and reports detailing the success of its efforts to fight fraud, taxpayer savings, and audit results.
