Ohio officials plan to ask federal regulators to allow premiums to be charged to nondisabled, working-age adults on Medicaid who have incomes of less than 138% of the federal poverty level. The requirement would affect more than 1 million of the 3 million Ohioans. Under the proposal, premiums - the lesser of 2% of household income or $99 annually - would be paid into a modified HSA. If premiums are 60 days late, Medicaid coverage is suspended until the money is paid; pregnant women are exempted. The plan is subject to approval by CMS, as premiums are not allowed under current law. Advocates project that premiums could result in an enrollment decline of up to 15% and cause those with chronic conditions or mental illness to go without care or medications.
