Humana Insurance Co. has agreed to pay $1.8 million in fines and $2.7 million in restitution to Missouri and other states resolve complaints about its sale of small group health insurance.

The Missouri Department of Insurance alleged that Humana required small employers to buy group life insurance in order to get small group health coverage. Such bundling violates insurance regulations. Ten states will divide the fine. Missouri regulators led the investigation with regulators from Wisconsin and Mississippi.
