Follow-up Audit of Medicaid Clinical Laboratory Services at the Illinois Department of Public Aid - Springfield, Illinois

The objective of our audit was to determine whether IDPA had taken satisfactory corrective actions with respect to previously reported findings related to Medicaid payments for clinical laboratory services.

Our follow-up audit determined that IDPA had implemented certain computer edits and updated its provider instructions as recommended in the previous audit. However, IDPA has not taken any action to recover payments in excess of Medicare bundled rates from the largest providers as previously recommended. In their response to our draft report, the IDPA concurred with our first two recommendations, but did not concur with our recommendations to recover estimated overpayments.
