Senate Bill 311 aims to prohibit the use of state and local funds, as well as federal funds passing through the state treasury, for health care services provided to individuals who are unlawfully present in the United States. Specifically, the bill creates a new statute, 20.926, which states that no funds from the state, counties, villages, towns, long-term care districts, or any subdivisions or agencies of these entities can be used to subsidize, reimburse, or compensate for health care services for such individuals.

However, the bill includes exceptions: the prohibitions do not apply if federal law requires the payment of funds for these services, nor if enforcing the restrictions would lead to the loss of federal funds. This legislation reflects a significant shift in funding policy regarding health services for unlawfully present individuals in Wisconsin.
