Obamacare: Report highlights the 'ridiculous' Medicaid coverage gap in the US

Medicaid expansion has become a key political issue under the Affordable Care Act (ACA) — commonly known as Obamacare.

In 2012, the Supreme Court ruled to leave decisions up to states on whether to adopt the ACA's expansion. In the decade since, 10 states still haven’t expanded Medicaid. That translates to more than 2 million individuals without healthcare coverage in a “coverage gap” that the Supreme Court decision created.

Here's how the gap happens: To qualify for Medicaid, an individual cannot make more than 138% of the federal poverty level, an income currently equivalent to $20,120. However, that's only under the ACA's expansion. The threshold for subsidies under traditional insurance plans in the Affordable Care Act is incomes above 100% of the federal poverty level.

That has left those 2 million-plus people in a situation where they are both living in poverty but also ineligible for financial assistance.

“The plight of these people — it’s just terrible,” Sherry Glied, dean and professor at Robert F. Wagner Graduate School of Public Service at New York University, told Yahoo Finance. “Imagine that you’re in a state where somebody says, 'OK, you can work another 10 hours this week, and if you work another 10 hours, you’re going to lose your health insurance coverage.' That’s ridiculous.”

A new report from the Commonwealth Fund, cowritten by Glied, highlights how the majority of these individuals in the coverage gap are people of color and people living in the South, where most of the non-expansion states are located. Previous studies have found that the size of the Black population in the state is predictive of whether that state expands Medicaid or not. States with particularly large Black populations have been the ones that haven't, Glied said.

“This is a particularly disadvantaged population because they have no recourse,” Glied said. “There’s nowhere for them to get health insurance. There’s no way they could possibly buy health insurance in the open market. They don’t have enough money and they don’t qualify for Medicaid. And this is the group that’s called the ‘gap population.’”

'A strong political stance'

One of the most notable impacts of Medicaid expansion was substantially increasing health insurance coverage rates.

According to the report, which compared outcomes for people who potentially fall in the coverage gap in comparable states that did and didn’t expand Medicaid, insurance coverage rates among parents in expansion states increased by 15.3% — and among nonparents by 10.5%.
