Summary
Illinois hospitals must ensure accurate billing for high-dollar inpatient claims to prevent inappropriate outlier payments. Data entry errors and insufficient documentation have led to incorrect charges that will be recouped by the state.
Action Required
Immediately: Hospital billing teams must implement enhanced accuracy checks for all high-dollar inpatient claims before submission. Review all UB-04 forms for data entry errors and ensure adequate documentation supports all charges. Sign and maintain HFS 194-M-C Billing Certification forms for three years. Establish internal audit processes to prevent erroneous charges that will result in recoupment and administrative penalties.
