The United States Government Accountability Office (GAO) has issued a report on improper payments in Medicaid managed care plans.  GAO found that about three-quarters of Medicaid beneficiaries are in managed care, under which states pay private health plans a set fee per person to cover care, and that Medicaid managed care's improper payment estimate has been at or near 0% -- but that there are risks that are not accounted for in the estimate, including payments from managed care plans to providers for services that were not delivered, rendering the 0% estimate of questionable value.  To read the GAO report on Medicaid managed care improper payments, use the first link below.  To read GAO highlights of the report on Medicaid managed care improper payments, use the second link below.
