ACA’s Medicaid eligibility expansion in Illinois

Medicaid is an important part of overall health insurance enrollment and coverage in Illinois, with Medicaid and CHIP covering about 20% of the state’s 12.5 million residents. About 20% of those covered are eligible for Medicaid due to the state’s expansion of Medicaid under the Affordable Care Act (ACA). The Illinois Department of Healthcare and Family Services maintains a running update of total enrollment numbers; as of August 2021, there were 789,974Illinois residents covered under expanded Medicaid.

Total Medicaid enrollment includes people who are eligible under the ACA’s expansion of Medicaid to low-income adults, as well as people who were already in one of the traditional Medicaid groups (low-income people who are also either pregnant, children, parents of minor children, aged, blind, or disabled residents). Most Illinois Medicaid enrollees are in one of those traditional eligibility groups, although enrollment in those groups has declined while enrollment in expanded Medicaid has grown. As of June 2021, total Medicaid enrollment in Illinois stood at more than 3.3million people — up from 2.62 million in 2013.

There has been a significant increase in Medicaid enrollment during the COVID pandemic, due to the widespread job and income losses. Under the Families First Coronavirus Response Act, enacted in the early days of the pandemic, states are receiving additional federal Medicaid funding, but on the condition that they not disenroll anyone from their Medicaid programs (unless the person moves out of state or requests a disenrollment). So Medicaid enrollment has generally just trended upward since early 2020, without the normal fluctuations we’d tend to see as people transition in and out of Medicaid.

Illinois’ uninsured rate has dropped from 12.7% in 2013 to 7.4% in 2019 (it had been even lower in 2016, at 6.5%, but has crept up since then).

Medicaid funding for enhanced mental health care

In September 2016, Illinois officials requested permission from the federal government to use existing Medicaid funds (with no changes to eligibility or funding) to test different approaches to treating Medicaid enrollees whoneed mental health and/or substance abuse treatment. The state had planned to implement the changes in July 2017, but CMS didn’t approve the waiver proposal until May 2018.

The idea is to focus more on preventive care, supportive housing services, and community-based care, rather than institutional care. The state notes that while 25% of Illinois Medicaid enrollees have mental health and/or substance abuse diagnoses, their treatment accounts for 56% of the Medicaid program’s total cost.

Under the terms of the approved waiver, Illinois is running ten pilot projects that provide coverage for services that weren’t previously covered by Medicaid, including short-term inpatient substance abuse treatment, services to help people manage withdrawals during substance abuse recovery, home health visits for new babies and for children born to opioid-addicted mothers, and job coaching and transportation services designed to help people obtain and keep employment.

Hepatitis C drug coverage expanded in stages, now available to anyone with the disease

In the past few years, drugs that can cure Hepatitis C have burst onto the medical scene, heralded as miracles. But they can also be a strain on budgets, as the pill initially could cost more than $1,000 per day, and the treatment course lasts 12 weeks. Medicaid programs across the country have been grappled with how to handle the situation, and Illinois announced in September 2016 that they would loosen their guidelines in terms of when Hepatitis C drugs would be covered.

Rather than restricting coverage only to the sickest patients, Illinois Medicaid began to cover Hepatitis C drugs for people with stage 3 and 4 liver scarring, rather than just 4. Advocates cheered the new rules, but cautioned that there was still no coverage for treatment in people with chronic Hepatitis C that hadn’t progressed as far as stage 3 liver scarring, and urged the state to continue to consider the issue.

By 2018, the price of Hepatitis C medications had declined, and a generic version was set to hit the market in early 2019, priced at $24,000 for the full treatment course (as opposed to $90,000 in the early years that the drug was available). And in October 2018, the state eliminated the restrictions on access to Hepatitis C drugs, allowing several thousand Illinois residents to obtain Hepatitis C medication through Medicaid, regardless of the stage of their disease and without having to prove sobriety.

Who is eligible for Medicaid in Illinois?

Federal law specifies mandatory and optional coverage groups for Medicaid. States must cover the mandatory groups to receive federal Medicaid funding, and they qualify for additional funding if they cover optional groups.

The federal government specifies minimum thresholds for eligibility for the various groups, and states can set their requirements at or above the minimum threshold. Illinois has established requirements that are near national averages.

Illinois’ eligibility standards for Medicaid are:

  • Children ages 0-18 qualify with family income levels up to 147% of the federal poverty level (FPL); the Children’s Health Insurance Program covers children with family income up to 318% of FPL
  • Someone who is pregnant will qualify with family income up to 213% of FPL
  • Parents and other adults qualify with family income up to 138% of FPL

Note that all of those limits include a built-in 5% income disregard, which is part of the MAGI-based eligibility rules used to determine Medicaid eligibility for Medicaid expansion, pregnant people, and children.

Illinois Medicaid history

Medicaid was implemented in the state of Illinois in January 1966.

Individuals covered by Medicaid in Illinois can choose either a fee-for-service plan or a managed care plan. The Illinois DHS site explains these options.

Illinois has been slower than many other states in moving beneficiaries to managed care plans. However, the state did pass a law in 2011 that required expanding managed care to at least half the state’s Medicaid beneficiaries by Jan. 1, 2015. As of 2021, more than 80% of Illinois Medicaid enrollees were covered under Medicaid managed care plans.

In June 2014, then-Governor Pat Quinn signed a Medicaid reform bill. The law restored adult dental care and podiatry services, aligns Illinois law with federal law to provide Medicaid coverage to children who have been without private insurance for three months, streamlines hospital and nursing-home reimbursement, and more.

Illinois opted to expand Medicaid eligibility, as allowed by the ACA, in July 2013 for a January 1, 2014 effective date. Making Medicaid available to low-income, non-elderly adults is a key part of the Affordable Care Act’s strategy to reduce the nation’s uninsured rate. However, a Supreme Court ruling made Medicaid expansion optional, and as of 2022, there were still 12 states that had not expanded Medicaid.

The federal government paid 100% of the cost for the Medicaid expansion population through 2016. After that, the federal government’s portion gradually decreased, reaching 90% by 2020, with Illinois covering the other 10% (it will remain at that level going forward).

At the time Medicaid expansion was approved, Illinois officials estimated that 342,000 Illinois residents would qualify. But according to the Chicago Tribune, about 350,000 new enrollees were approved in just the first several months, by June 2014. And a little over a year later, by August 2016, total enrollment in the state’s Medicaid expansion program had exceeded 646,000. But enrollment had dropped to606,670 people as of July 2018, and remained at a very similar level (607,404) as of April 2020. That was still far higher than the state had initially projected, but lower than it had been a few years earlier. However, the COVID pandemic pushed Medicaid enrollment (including Medicaid expansion enrollment) much higher. By August 2021, nearly 790,000 people were enrolled in expanded Medicaid in Illinois.

By May 2021, total enrollment in Medicaid and CHIP in Illinois stood at more than 3.3 million, and was 27% higher than it had been at the end of 2013. The total CHIP/Medicaid population includes people who were already enrolled in Medicaid pre-2014, people who were eligible but not yet enrolled at that point, and people who gained eligibility as a result of the ACA’s expansion of Medicaid.
