What is a coverage plan that can supplement a primary benefit called?

A coverage plan that supplements a primary benefit is referred to as secondary coverage. This type of insurance is designed to provide additional financial support alongside a primary insurance policy. When a primary coverage plan has been utilized, secondary coverage can help to pay for remaining eligible expenses that may not be covered, such as deductibles, copayments, or other out-of-pocket costs.

Secondary coverage is especially beneficial in scenarios like healthcare, where having multiple layers of insurance can reduce the financial burden on the insured individual. It ensures broader protection and can enhance the total benefits received from both policies, resulting in reduced overall costs for medical care or other covered services.
