Medicaid Redetermination Process Prior to February 2018

​The Illinois Department of Healthcare and Family Services (HFS) and the Illinois Department of Human Services (DHS) have launched a project to process the backlog of cases that require immediate redeterminations and ensure that going forward, redeterminations will be processed in a timely manner, so that eligibility for Medicaid coverage is verified on an annual basis.

The Illinois Medicaid Redetermination Project (IMRP) will improve Medicaid integrity by validating that clients who qualify for medical benefits receive them, while those that are not qualified are dis-enrolled. The state’s Medicaid program will use advanced data matching technology to verify income and residency of the state’s 2.7 million Medicaid clients on an annual basis
