More than 13,000 people on Medicaid in Arkansas failed to report whether they had worked in February, according to figures provided Friday by the state, putting them on track to lose coverage under the new work requirements.

Arkansas has work requirements that mandate that people work, take classes, or volunteer at least 80 hours a month to be allowed to stay in Medicaid, a government-funded program that provides medical coverage to poor people. Advocates for people who were kicked off Medicaid have challenged the rules in court, and they may be put on hold by a federal judge later this month.

The number of enrollees who did not work, or failed to report that they worked, jumped in February to 13,373. In January, 10,258 did not meet the requirement. Anyone who fails to meet the requirement for three months is kicked off the program for the rest of the year. So far, 6,472 people have not met the work requirement in both January and February, and if they fail to report hours in March they will be kicked off Medicaid.

During last year's program, which started in the middle of the year, more than 18,000 people were kicked off Medicaid.

This year the requirements apply to even more people. When they went into effect last year, people between the ages of 30 to 49 had to follow them. For 2019, the rules were extended to people between the ages of 21 to 29. The rules apply to people who got Medicaid under the Obamacare expansion, meaning anyone making roughly $17,000 a year or less.

Work requirements have been encouraged by the Trump administration, which argues that adults who are not disabled should be asked to work and eventually transition from Medicaid to private health insurance. At least seven state applications have been accepted, and other states have asked to follow.

Critics contend that the programs are instead causing people to become uninsured and that the measures are an attempt to kick people off of the program. The work requirements don't need to be followed for the majority of people on the program, including caregivers, parents, or those receiving addiction treatment.
