Deductibles are an element of any insurance product, but as deductibles have grown in recent years, a surprising percentage of people with private insurance, and especially those with lower and moderate incomes, simply do not have the resources to pay their deductibles and will either have to put off care or incur medical debt.

The chart above, based on a Kaiser Family Foundation study published Wednesday, shows that about a quarter of all non-elderly Americans with private insurance coverage do not have sufficient liquid assets to pay even a mid-range deductible, which at today’s rates would be $1,200 for single coverage and $2,400 for family coverage. We found that more than a third don’t have the resources to pay higher deductibles.
