Wisconsin Insurance Commissioner Sean Dilweg is imposing a $750,000 fine on a health insurer.
Dilweg is imposing the fine on Humana Insurance Company, a unit of Humana Inc., Louisville, Ky.
Wisconsin regulators found a number of concerns, including evidence that Humana may have paid commissions it should not have paid to agents selling Medicare Advantage and Medicare Part D plans.
The examination that led to the fine covered a period extending from 2005 to 2007.
Humana has agreed to pay the fine to resolve the investigation but has denied the allegations in the Wisconsin exam report and any violation of the law.
