A state legislator has asked that the auditor’s office look into the Iowa Medicaid program and the managed-care organizations it oversees. The request came after cost-savings estimates released by a state department differed from previous estimates.Sen. Pam Jochum, D-Dubuque, sent a letter to State Auditor Mary Mosiman on Tuesday requesting that her office seek documentation from the Iowa Department of Human Services and the private companies that administer Medicaid coverage “to determine if Iowans are really saving money by paying out of state, for-profit insurance companies to care for our most vulnerable,” according to the letter obtained by The Gazette.“Auditor Mosiman has said her unofficial office motto is, ‘In God We Trust … Everyone Else We Audit,’ Jochum said in a news release Tuesday.
