What is a key advantage of having Secondary Insurance?

A key advantage of having secondary insurance is that it provides coverage for services that remain unpaid by primary insurance. This means that if a claim is partially covered or denied by the primary insurer, secondary insurance can help cover the remaining balance, reducing the financial burden on the individual. This is particularly beneficial for individuals with significant medical expenses or those who require ongoing treatment, as secondary insurance can fill in gaps in coverage and ensure better overall financial protection against medical costs.

The other options do not accurately represent the main advantage of secondary insurance. For instance, while it can reduce out-of-pocket costs, it does not eliminate all of them. Additionally, secondary insurance does not automatically apply to all medical expenses, as it typically only addresses the costs that the primary insurance has not fully covered. Lastly, secondary insurance does not inherently lower the premium of the primary insurance; it is a separate policy that may require its own premium payment.
