For employers that are looking for peace of mind, a Fully Insured plan might be the way to go.
Payments

The company pays a premium, typically fixed for a year, to the insurance carrier. The monthly premium normally only changes during the year if the number of enrolled employees in the plan changes
Benefit Design

The covered persons (that is, employees and dependents) are responsible to pay any deductible amounts or co-payments required for covered services under the policy. These plans are usually limited by the insurers plan designs.
Assumption of Risk

The insurance carrier collects the premiums and pays the health care claims based on the coverage benefits outlined in the policy purchased.
Regulation

The Plans must comply with federal AND state regulations
