Jun 21, 2026
Summary
HFS (Illinois Medicaid) is implementing changes to UB-04 claim editing to comply with NUBC definitions for Admission Date (FL 12) and Statement Covers Period (FL 6). The key change is that Admission Date and From Date are no longer required to match, and days in Statement Covers Period cannot be compared to accommodation days.
Action Required
Wait for further notice from HFS before implementing changes: Do not modify current billing practices for Illinois Medicaid claims until HFS provides additional guidance. When notified, billing team must update UB-04 claim submission logic to separate Admission Date (FL 12) from Statement Covers Period From Date (FL 6) - these fields no longer need to match. Contact hospital's medical assistance consultant at 1-877-782-5565 with questions.
