No. Wisconsin has not adopted the ACA's Medicaid expansion. Instead, it runs BadgerCare Plus, which covers childless adults up to 100% of the Federal Poverty Level rather than the ACA's 138% FPL expansion threshold, making Wisconsin a partial-expansion/non-expansion state.
The detail behind the program
It's important to keep this separate from long-term-care Medicaid eligibility for seniors, which is a different question entirely -- Wisconsin's long-term-care Medicaid pathway (covering nursing-home care, and Family Care/IRIS for community-based services) uses its own aged/blind/disabled, non-MAGI income and asset rules, not the BadgerCare Plus expansion pathway described here. A senior or their family evaluating whether Medicaid will help pay for care should ask specifically about long-term-care Medicaid eligibility, not general BadgerCare Plus expansion coverage, since the two use entirely different eligibility tests despite both being administered by the same state agency.
