South Dakota and the ACA’s Medicaid expansion

South Dakota voters have approved a Medicaid expansion ballot measure; Eligibility rules will change as of July 2023

Medicaid eligibility set to be expanded in July 2023

South Dakota is one of 12 states where federal funding to expand Medicaid has not yet been accepted by the state, due to opposition from the legislature and governor. But as described below, the issue was put to the state’s voters in the 2022 election, and voters approved Medicaid expansion by a 56% to 44% margin. The measure calls for the state to expand Medicaid eligibility on July 1, 2023.

For now, prior to July 2023, eligibility rules in the state remain the same as they were prior to the Affordable Care Act (ACA). Coverage under Medicaid is only available in South Dakota for those with low income who are either children, elderly, pregnant, disabled, or very low-income parents/caretakers of minor children (parents are only eligible with household income up to 63% of the poverty level, which works out to just over $14,500 a year for a household with three people). Children comprise more than two-thirds of the state’s Medicaid population.

Low-income childless adults without a disability are ineligible for Medicaid regardless of how low their income is, but they’re not eligible for premium subsidies to offset the cost of private coverage unless their income is at least 100% of the poverty level. This leaves an estimated 14,000 low-income South Dakota adults in the coverage gap, with no access to any financial assistance with their health coverage. They will become eligible for Medicaid in July 2023, once the state expands Medicaid eligibility under the terms of the ballot measure that voters approved in 2022.

At that point, a single person would qualify for Medicaid in South Dakota with an income of up to about $18,754 (that number increases a little each year as the poverty level rises; it will be higher by the time Medicaid expansion takes effect in South Dakota).

South Dakota Medicaid expansion approved by voters

Most of the states that have expanded Medicaid have done so via legislation. But as time goes on and lawmakers and/or governors in a dwindling number of states continue to reject federal funding to expand Medicaid, the issue is increasingly being taken directly to voters. Medicaid expansion has already taken effect in Maine, Utah, Idaho, Nebraska, Oklahoma, and Missouri as a result of ballot measures that were approved by voters (Medicaid expansion via ballot measure has been successful in all of the states where voters have had an opportunity to directly decide whether the state should expand Medicaid).

In South Dakota, Former Governor Dennis Daugaard supported Medicaid expansion by 2015 (after initially opposing it), but the issue did not have lawmakers’ support. Current Governor Kristi Noem is opposed to Medicaid expansion, and the legislature has also continued to oppose Medicaid expansion. But as has been the case in every other state where voters got to weigh in directly on the issue, South Dakota voters have approved a constitutional amendment (Amendment D) to expand Medicaid eligibility as called for in the ACA.

In order to get the measure on the ballot, Medicaid expansion supporters in the state gathered more than 38,000 signatures. There were concerns that the measure might need 60% approval to pass, as voters also had the opportunity to vote on South Dakota Constitutional Amendment C in the June 2022 primary election. That measure was defeated, but if it had been approved it would have required 60% voter approval for future ballot measures that increased taxes or require the state to appropriate more than $10 million. If voters had approved Amendment C, Amendment D would have needed to be approved by at least 60% of voters in order to pass. But since Amendment C did not pass, Amendment D only needed a simple majority in order to pass (it ultimately got 56% of the vote).

Amendment D calls for the state to submit a state plan amendment to the federal government by March 1, 2023, detailing the state’s plan for the expansion of Medicaid. And the expanded eligibility rules will take effect July 1, 2023. Over the next five years, South Dakota will receive nearly $1.5 billion in additional federal Medicaid funding once Medicaid expansion is in effect.

Does South Dakota have a Medicaid work requirement?

No, although the state sought federal approval to implement a work requirement. Instead of expanding Medicaid during any of the legislative sessions since 2010, South Dakota opted to seek federal approval for a pilot program work requirement for low-income parents in the existing Medicaid program (the pilot program would have applied in just two counties initially).

Former Governor Dennis Daugaard laid out the details of the work requirement in his State of the State address in January 2018, and the state published the proposed waiver application in May 2018. The waiver proposal has been pending CMS approval since 2018, but the Biden administration notified states in 2021 that Medicaid work requirements were essentially a non-starter; all of the previously approved work requirements were revoked by the Biden administration in 2021, and no pending work requirement proposals have been approved. South Dakota began voluntary enrollment in the Career Connector program in July 2018.

South Dakota Medicaid enrollment numbers

As of mid-2022, enrollment in South Dakota’s Medicaid program stood at 140,676 people. Because the state has not expanded Medicaid, enrollment has not grown the way it did in most other states. There were about 115,500 enrollees in late 2013, and most of the subsequent growth has happened during the COVID pandemic.

States are receiving additional federal Medicaid funding during the pandemic emergency period, but on the condition that Medicaid enrollees not be dropped from the program. So eligibility redeterminations have not been conducted since March 2020, which means Medicaid enrollment has generally trended upward, nationwide, ever since then.

South Dakota Medicaid history

South Dakota’s Medicaid program became effective in October 1967, nearly two years after Medicaid was created. For many states, 2014 represented a significant shift in eligibility, particularly for childless adults. However, South Dakota Medicaid eligibility guidelines have not yet changed under the ACA. Non-disabled childless adults are ineligible for Medicaid, regardless of how low their incomes are. But as noted above, that might change after voters have an opportunity to weigh in on Medicaid expansion on the 2022 ballot.

South Dakota Medicaid expansion history

South Dakota officials announced in September 2015 that their proposal to expand Medicaid had received “an initial go-ahead” from HHS. then-Governor Dennis Daugaard’s senior advisor Kim Malsam-Rysdon noted that the plan was still preliminary, but it appeared promising and would have expanded eligibility to far more people than the state’s 2014 proposal, which would only have expanded coverage to residents with incomes below the poverty level (HHS rejected that proposal, as Medicaid expansion capped at the poverty level — but with the enhanced federal Medicaid expansion funding match — was a non-starter under the Obama administration, and was also rejected by the Trump administration when proposed by Utah).

Of the population that would have been newly eligible for coverage under Medicaid expansion, more than a quarter — about 14,000 people — are Native Americans, although Native Americans make up just nine percent of the South Dakota population. Native Americans are disproportionately impacted by the state’s refusal to expand Medicaid. Although they are eligible for free care through Indian Health Services, the treatment options are limited at those facilities. The approval from HHS to allow non-IHS providers to enter into care coordination agreements with IHS facilities was expected help to open up treatment options for Native Americans with Medicaid coverage, with full funding from the federal government, but Daugaard had noted that it’s a complicated process, and not all providers enter into those agreements.

Although states that expanded Medicaid are paying 10% of the cost, Daugaard noted that his proposal would have ended up being a financial net positive for the state. That’s because he was working with the federal government and Native American tribal leaders to use Medicaid funding for Native Americans who would become eligible for expanded Medicaid and who receive treatment outside of Indian Health Services (IHS) facilities. Those costs are covered in part by the state, and Daugaard said that South Dakota would save more there than it would spend on its portion of the Medicaid expansion costs. Daugaard said that he wouldn’t continue his push for Medicaid expansion if it ended up needing additional money from the state’s general fund.

In December 2015, Governor Daugaard explained the details of his $4.8 billion budget proposal, including his proposal to expand Medicaid to cover 55,000 people who weren’t currently eligible. Daugaard said that the state should “seize the opportunity” to use federal funding to expand coverage, if possible.

In February 2016, HHS agreed to establish arrangements under which non-IHS providers could enter into “care coordination agreements” with IHS facilities, and Native Americans enrolled in Medicaid would be able to receive care at those non-IHS facilities and the full cost would be covered by federal Medicaid funds (as opposed to the state paying a portion and the federal government paying a portion). But Daugaard noted that the practical implementation of the new HHS provision could be complicated, and that there was still work to be done to determine whether the savings from the new IHS rule would save enough money to make Medicaid expansion budget-neutral in South Dakota.

A few days later, Daugaard said that it was too late in the 2016 legislative session to get the ball rolling on Medicaid expansion, and said that he would remove Medicaid expansion from his proposed budget. He indicated that a special session was a possibility, but that waiting until the 2017 legislative session was also a possibility. In June 2016, Daugaard confirmed that the issue would have to wait until the 2017 legislative session, as he was opting not to call a special session in 2016.

In early 2017, in his State of the State address, Daugaard noted that he was optimistic about working with the Trump administration to ensure that the federal government would begin to fully fund medical care for Native Americans, regardless of where the care was provided, without requiring “health care providers to jump through several hoops,” as he believed the Obama-era arrangement did. He did not mention Medicaid expansion in that address.

The issue of Medicaid expansion was essentially off the table in South Dakota as of early 2017. The coalition tasked with recommending how the state should expand coverage updated their conclusions in December 2016 to note that Governor Daugaard was no longer recommending Medicaid expansion for 2017, in light of the incoming Trump administration’s plans to overhaul Medicaid nationwide with block grants or per-capita allotments. Ultimately, that did not come to pass at the federal level, but no progress has been made toward Medicaid expansion in South Dakota in the meantime.

Kristi Noem took office as governor in 2019, and opposes Medicaid expansion. But voters in the state had an opportunity to decide the matter for themselves on the 2022 ballot, and they approved Medicaid expansion by a vote of 56 to 44. This paves the way for Medicaid expansion to take effect in South Dakota as of July 2023.
