LITTLE ROCK, Ark. — Arkansas lawmakers are scheduled to discuss whether the federal waiver for the state's compromise Medicaid expansion conflicts with the state law that paved the way for the measure last year.

The House and Senate Public Health, Welfare and Labor committees are scheduled on Tuesday to discuss the state's "private option" Medicaid expansion with officials from the state Department of Human Services.

Under the private option, Arkansas is using federal Medicaid money to purchase private insurance for thousands of low-income workers. It was approved last year as an alternative to expanding Medicaid under the federal health care law.

The expansion is at risk of being defunded when the Legislature convenes later this month. Opponents have questioned whether the federal waiver for the expansion complies with the state law.
