If you're not doing so already, take steps to discourage employees and dependents from holding duplicate health coverage.
Example: Ford Motor Co. is now requiring employees to disclose whether their spouses on their health plan have duplicate health coverage at their own jobs or elsewhere. When spouses have their own coverage, Ford will require employees to pay extra into the health insurance plan. Ford's goal is to avoid paying for costly duplicate coverage for employees' spouses and families.
Other companies encourage such double-covered spouses to get off their health plans by paying them an incentive bonus. Before doing so, make sure you obtain verification that the employee's spouse actually is covered elsewhere.
