Summary

The Illinois Department of Healthcare and Family Services published proposed amendments to 89 Ill. Adm. Code 110 and 120 to implement Medicaid work requirements and redetermination period changes mandated by federal Public Law 119-21, the 'Working Families Tax Cut' legislation, effective January 1, 2027. The proposal follows the CMS Interim Final Rule published June 3, 2026, and amends sections governing the application process and medical assistance programs consistent with Social Security Act sections 1902(xx), 1902(e)(14), and 1902(a)(34). The same Register issue includes proposed amendments to the Health Care Worker Background Check Code at 77 Ill. Adm. Code 955. Written comments are due within 45 days of publication.

What this may mean

Illinois Medicaid ACA Adult enrollees will be subject to new work requirements and revised redetermination periods effective January 1, 2027, consistent with federal mandates. Illinois providers and managed care organizations serving ACA Adult Medicaid beneficiaries will face potential changes to the covered population due to eligibility redeterminations under the new requirements. Retroactive Medicaid coverage rules will also be amended across all coverage groups.
