CIGNA Corp. and Humana Inc. announced plans to work together selling Medicare Advantage to employers that offer health coverage to retirees, the Hartford Courant reports. The agreement allows CIGNA Corp. to sell Humana's Medicare Advantage plan to CIGNA's group-based customers. CIGNA will continue to manage the accounts, but the retirees will have a Humana plan and access to Humana's network of doctors and hospitals.
