They might be trying to determine if they are your primary or seconday insurance coverage. Don't sweat it just answer them honestly.
They're looking to see if you've got the insurance that people over 65 years old are eligible for. I assume that your answer is "no".
it means that your health insurance will only pay for your health coverage after deducting your medicare
