Indianapolis disability service agency Easterseals Crossroads will join health insurance giant Anthem to provide these services.

The deal, proposed in a class-action suit over a 2015 data breach affecting nearly 80 million people, would be the largest-ever in such a case if approved.

MDwise and Anthem - the only two companies with plans currently available in every county - announced within hours of each other Wednesday that they were leaving Indiana's Affordable Care Act exchange.

Big health insurers have to work harder to prove planned mergers are necessary to save money - and that they won't use their new market power to raise prices.

Anthem killed the $54-billion deal Friday after a failed bid to keep Delaware-based Cigna at the bargaining table.

Cigna officials announced Tuesday they had sued Anthem in a Delaware court seeking a judge's affirmation that the company had lawfully ducked out of the merger agreement.

If the deal doesn't go through by April 30, Anthem could be forced to pay Cigna a nearly $2 billion "breakup fee."

Indiana is one of 14 states where a single insurer holds at least 50 percent of the market.

If completed, the Anthem-Cigna merger could be among the largest in history. But before the takeover happens, the companies need to prove the deal won't violate federal anti-trust laws.

Anthem's deal with Connecticut-based Cigna had been in the works for more than a year. However, in recent months experts started speculating about the feasibility of the $48 billion merger, reasoning the deal could potentially violate anti-trust laws.
