Summary
Illinois Medicaid has introduced the Medical Electronic Data Interchange (MEDI) system, a free internet-based platform for Medicaid-enrolled providers to verify patient eligibility. This system is separate from the existing REV system and currently only supports eligibility verification for long-term care facilities.
Action Required
Long-term care facilities should visit http://www.myhfs.illinois.gov/gettingstarted.html to enroll in the MEDI system for free eligibility verification. Contact Bureau of Long Term Care at 1-217-782-0545 for questions. This is optional as REV system remains available.
