This summer, the state of Louisiana texted just over 13,000 people enrolled in its Medicaid program with a link to a website where they could confirm their incomes.

The texts were part of a pilot run to test technology the Trump administration says will make it easier for some Medicaid enrollees to prove they meet new requirements — working, studying, job training, or volunteering at least 80 hours a month — set to take effect in just over a year.

But only 894 people completed the quarterly wage check, or just under 7% of enrollees who got the text, according to Drew Maranto, undersecretary for the Louisiana Department of Health.

“We’re hoping to get more to opt in,” Maranto said. “We plan to raise awareness.”

The clock is ticking for officials in 42 states — excluding those that did not expand Medicaid at all — and Washington, D.C., to figure out how to verify that an estimated 18.5 million Medicaid enrollees meet rules included in President Donald Trump’s tax and spending law. They have until the end of next year, and federal officials are giving those jurisdictions a total of $200 million to do so.

The policy change is one of several to free up money for Trump’s priorities, such as increased border security and tax breaks that mainly benefit the wealthy.

The nonpartisan Congressional Budget Office has said the work rules will be the main reason millions of people won’t be able to access health insurance over the next decade. It estimates changes to the Medicaid program will result in 10 million fewer Americans covered by 2034 — more than half of them because of the eligibility rules.

For now, state officials, health policy researchers, and consumer advocates are watching the pilot program in Louisiana and another in Arizona. Mehmet Oz, director of the Centers for Medicare & Medicaid Services, has touted those test-drives and said they will allow people to verify their incomes “within seven minutes.”
