From A Press Release
JEFFERSON CITY (March 7, 2013) – State Auditor Tom Schweich today released the audit of the Medicaid Management Information System Data Security, housed within the Missouri Department of Social Services (DSS) and MO HealthNet Division (MHD). State law requires the auditor to audit all state agencies.
In the areas audited, the overall performance of this entity was Good.
The MHD paid claims of more than $62,400 during calendar year 2011 for services that should not have been allowed because three edit checks were not functioning properly. An authorized user may override a denied claim, but the MHD cannot always track the identity of users who performed an override, which reduces accountability.
DSS management could not identify the user of an account with privileged access to the MMIS. Failing to identify all users with privileged access to the MMIS could leave the system at risk of improper modification. Audit staff found 66 active user accounts for individuals who were no longer employed by DSS or one of its contractors.
The MMIS is the Medicaid benefit claims processing and information retrieval system used by the state to meet requirements of the United States Department of Health and Senior Services. The MMIS is owned by the state but is operated and maintained by a contracted vendor. The scope of Schweich's audit included security controls and other relevant internal controls established and managed by DSS and MHD.
