55 ILCS 5/5-1069.2: Post-parturition care.

If a county, including a home rule county, is a self-insurer for purposes of providing health insurance coverage for its employees, the coverage shall include coverage for the post-parturition care benefits required to be covered by a policy of accident and health insurance under Section 356s of the Illinois Insurance Code. The requirement that post-parturition care be covered as provided in this Section is an exclusive power and function of the State and is a denial and limitation under Article VII, Section 6, subsection (h) of the Illinois Constitution. A home rule county to which this Section applies must comply with every provision of this Section.
