Summary
Illinois Medicaid has added two new indicators to the patient credit file in the MEDI system for Long Term Care providers. The system now displays 'P' for residents with Provisional Eligibility and 'M' for Medicare-only admissions in the 100th character position.
Action Required
Long Term Care billing teams should update their MEDI system procedures to recognize the new 'P' and 'M' indicators when downloading weekly patient credit files. Verify that billing software can properly process these new indicators in the 100th character position.
