An annual back-to-school campaign aimed at enrolling children in low-cost government insurance is now trying to get their parents and other adults signed up, too. Indiana Health Commissioner Judy Monroe, state schools superintendent Suellen Reed and Medicaid chief Jeff Wells joined advocates from Covering Kids & Families of Indiana in appealing to low-income families to enroll their children in Hoosier Healthwise and themselves in the new Healthy Indiana Plan. More than half a million Indiana residents who lack basic healthcare coverage might qualify for free or low-cost health insurance through the state programs, advocates said.
