TOPEKA — The chief executive officer of one of the private insurance companies that recently signed Medicaid managed care contracts with the state of Kansas said today that states shouldn’t refuse the offer of additional federal money to expand their programs.

James Carlson, CEO of Amerigroup, made the comment during a discussion with Wall Street analysts about his company’s potential sale to insurance giant WellPoint.

“When you step back from this, there are billions of dollars of federal money that are going to flow into states,” Carlson said in a report published by Politico. “We think the states are going to need to take it.”

Kansas insurance officials are evaluating WellPoint’s bid for Amerigroup, which is one of three companies selected by the state to manage care provided to the approximately 350,000 poor, elderly and disabled Kansans enrolled in Medicaid. The other two are United Healthcare of the Midwest, a subsidiary of United Healthcare, and Sunflower State Health Plan, a subsidiary of Centene.

Several Republican governors have said they don’t intend to expand eligibility for their Medicaid programs now that the U.S. Supreme Court has ruled that the federal government can’t withhold its share of funding for the program in states that decline to do so.

Kansas Gov. Sam Brownback has reiterated his opposition to the Affordable Care Act in statements since the ruling, but he has stopped short of saying the state won’t implement the Medicaid expansion on schedule in 2014.

Brownback spokesperson Sherriene Jones-Sontag said the governor still favors repeal of the health reform law and has urged voters to reject it at the polls in November by voting against President Obama’s re-election.

The expansion would result in a more dramatic increase in Medicaid eligibility in Kansas compared to other states. Currently, Kansas adults with dependent children can’t qualify for the program unless they earn less than 27 percent of the federal poverty threshold – about $6,000 for a family of four. Adults without children aren’t eligible for Medicaid unless they are disabled. The ACA expansion would make everyone who earns less than 133 percent of the poverty threshold eligible for Medicaid. That means a family of four could earn up to about $30,000 and still qualify.

If implemented, the expansion could add as many as 150,000 Kansans to Medicaid rolls.
