Louisville-based Humana has agreed to be sold to Connecticut-based rival Aetna for $37 billion, the companies announced early Friday.

Officials with the Kentucky Department of Insurance have fined Humana $65,000 after investigating complaints about a letter the company sent to policyholders.

In August, letters were sent to over 6,000 members, saying they had 30 days to renew their plans for 2014, or they would have to choose a more expensive option that complies with the Affordable Care Act.

At the time, state officials pointed to the other two operators as proof of coverage. But now one of those operators, Kentucky Spirit, is leaving next July.
