The Supreme Court's 2012 ruling on the Affordable Care Act (ACA) allowed states to opt out of the law's Medicaid expansion, leaving each state's decision to participate in the hands of the nation's governors and state leaders.
The Daily Briefing editorial team has been tracking where each state stands on Medicaid expansion, combing through lawmakers' statements, press releases and media coverage. In this latest iteration of our Medicaid map, we've determined each state's position and outlined any possible expansion efforts.

NOT EXPANDING AT THIS TIME (10 STATES)
- Alabama: Then-Gov. Robert Bentley (R) in November 2015 said his administration was "looking at" expansion but has not yet "made a final decision" on whether to expand Medicaid or "exactly how that would work." The state has yet to move forward on expansion under Bentley or current Gov. Kay Ivey (R).
- Florida: The Florida Senate in 2015 approved a Medicaid expansion plan, but it was rejected by then-Gov. Rick Scott (R) and the state House. The state government almost shut down over a budget impasse linked to the issue, but state lawmakers in June 2015 reached an agreement on a final budget deal without an expansion. The state has yet to move forward on expansion.
- Mississippi: Republicans in the Legislature in June 2013 blocked plans to expand Medicaid to an additional 300,000 state residents under the ACA. Governor Tate Reeves (R), who was elected in November 2019, opposes Medicaid expansion.
- North Carolina: In 2013, the state's General Assembly passed a bill banning Medicaid expansion, but then-Gov. Pat McCrory (R) in October 2014 said that he would consider expanding Medicaid to an estimated 500,000 state residents. The state ultimately did not expand the program under McCrory. However, Gov. Roy Cooper (D) took office in Jan. 2017 and shortly thereafter announced plans to expand Medicaid through executive action. However, a federal judge has put a temporary stay on Cooper's Medicaid expansion request. North Carolina's Legislative leaders in July dropped their case because Cooper never filed a plan to expand Medicaid. They said they would refile their legal challenge if Cooper tries to advance an expansion plan.
- South Carolina: On March 12, 2013, the state House Republican majority rejected an expansion of Medicaid, opting instead to allocate $80 million in state and federal funding in South Carolina's budget for a hospital incentive payment program. Then-Gov. Nikki Haley (R) announced in July 2012 that she opposes expansion.
- South Dakota: Then-Gov. Dennis Daugaard (R) in Oct. 2013 said he was leaning against expanding Medicaid. Daugaard later proposed expanding the program during a budget address in December 2015. However, Daugaard in November 2016 announced he would no longer seek Medicaid expansion in his state amid then-President-elect Donald Trump's plans to repeal and replace the Affordable Care Act. The state has taken no additional action to expand Medicaid.
- Tennessee: Then-Gov. Bill Haslam (R) on Dec. 15, 2014, announced an alternative plan to expand the state's Medicaid program under the Affordable Care Act. The plan would use federal funds to extend coverage to an additional 200,000 low-income state residents by helping them to purchase health plans offered by their employers or by placing them in the state's Medicaid program. State residents with annual incomes up to $16,100, or 138% of the federal poverty level, would be eligible for the program. However, a key Senate committee in February 2015 voted against the proposal. Haslam in March 2017 said he was no longer considering expanding Medicaid.
- Texas: Then-Gov. Rick Perry (R) and the Republican majority in the state Legislature unanimously rejected the Medicaid expansion, although Democrats introduced legislation (HB 3791) that would establish a strategy to expand Medicaid. Perry's successor, Gov. Greg Abbott (R), also opposes Medicaid expansion.
- Wisconsin: Then-Gov. Scott Walker (R) on Feb. 13, 2013, said Wisconsin will not participate in the ACA Medicaid expansion, but will pursue its own strategy to expand health coverage across the state. In addition, the legislature's Joint Finance Committee in June 2013 voted against the expansion. Wisconsin has not adopted Medicaid expansion under the ACA but covers adults up to 100% FPL.
ACTIVELY CONSIDERING EXPANSION (2 STATES)
- Georgia: Former Gov. Nathan Deal (R) strongly opposed expanding Medicaid under the ACA and the state made no movement on expansion during his tenure as governor. But Gov. Brian Kemp (R), who took office in 2019, in March signed into law a bill that permits the state to seek federal approval for a partial Medicaid expansion and to impose Medicaid work requirements. In December 2019, the state submitted a proposed 1115 waiver request to expand Medicaid coverage to those at 100% FPL who work or take part in community engagement activities at least 80 hours per month. CMS on Oct. 15, 2020, approved the waiver and coverage is set to begin on July 1, 2021. However, it's not clear if the Biden administration will allow the partial expansion to remain in place.
- Kansas: Then-Gov. Sam Brownback (R) in 2013 and 2017 declined to expand Medicaid. But Gov. Laura Kelly (D), who was elected in 2018, and Republican leaders in the state Legislature on Jan. 9, reached a deal to expand the state's Medicaid program under the Affordable Care Act. The deal includes provisions to help enrollees find jobs. However, the bill stalled in the state Legislature.
- Wyoming: The state's Wyoming's Department of Health in November 2014 proposed an alternative Medicaid expansion plan that would extend the program to about 18,000 state residents with incomes up to 138% of the federal poverty level. The expansion plan called for a federal waiver to allow the state to charge monthly premiums and copayments to low-income individuals who choose to participate. However, the state Senate and House in February 2015 voted against the expansion plan, tabling the proposal for the rest of the legislative session. The state House in March passed a bill to expand Medicaid after Congress passed the American Rescue Plan, which gives states a 5% FMAP increase on their non-expansion populations if they expand Medicaid under the ACA. The bill now goes to the Senate.
