Cigna Corp., a leading health insurer, has managed to beat all estimates by posting a much better than expected third quarter report. The rise in the firm's earnings for the July-September period for the year has been attributed by the company to a strengthening stock market which surged the value of variable annuity products in the reinsurance business.

New York Attorney General Andrew Cuomo said health insurer Cigna Corporation will no longer use the faulty Ingenix database to calculate out of network reimbursement rates and will contribute $10 million to a new independent payment database.
