Update Regarding the COVID-19 Uninsured Portal
Illinois Medicaid - HFS·IL·Provider Notice
Effective date
Dec 16, 2022
We identified it
Jun 20, 2026
Summary
The COVID-19 Uninsured Portal remains non-operational, and when it resumes, providers must bill all COVID-related claims through their usual claim submission processes outside the portal. Hospitals must use specific claim formats (837I for testing/treatment, 837P exception for vaccines) and all claims must include COVID-related diagnosis codes or face recoupment.
Action Required
Immediately: Continue billing COVID-related claims for uninsured patients through usual claim submission processes outside the portal. Hospitals must ensure they use 837I format for COVID testing and monoclonal antibody claims, and 837P format for vaccine administration. All billing staff must verify that COVID-related claims include appropriate COVID or COVID-related diagnosis codes to avoid post-payment review and recoupment. Obtain SSNs from uninsured patients when available for future RIN requests.
