Summary
Illinois Medicaid has introduced three new error messages (N93, N94, N95) for hospital inpatient claims that span more than one year. These error messages inform hospitals when claims will be paid by special C-13 vouchers instead of normal processing, and hospitals should not rebill these claims.
Action Required
Immediately: Hospital billing teams must update their systems to recognize new error codes N93, N94, and N95 on remittance advices. Train staff to identify these messages and understand that claims spanning more than one year will be paid by C-13 voucher. Do not rebill claims that receive these error messages as they indicate special payment processing is in progress or completed.
