Consumer complaints have led to two insurance companies to pay fines to the state.

Conseco Health Insurance Co. has paid a $25,000 fine and Washington National Insurance Co. a $5,000 fine.

Conseco Health's fine ranks among the largest ever paid by an insurance company to the state.

Nebraska Department of Insurance investigators said Conseco Health failed to explain the denial of claims, overlooked claims and had delays in processing claims far greater than allowed by law.

Washington National was disciplined for failing to promptly pay medical and long-term care claims in 2007.
