Summary
Nursing facilities must electronically report ALL dual-eligible resident admissions to Department of Human Services caseworkers, even when the admission period is entirely covered by Medicare. This ensures continuous Medicaid coverage since Pre-Admission Screens are only valid for 90 days.
Action Required
Immediately: Nursing facility billing teams must report all dual-eligible Medicare admissions electronically to DHS caseworkers using COS 65 for days 1-20 and COS 72 for days 21-100. After Medicare exhaustion, report as COS 70 (Medicaid Skilled) or COS 71 (Medicaid Intermediate Care). Contact Bureau of Long Term Care at 217-524-0545 with questions.
