What is high deductible health plan? A high-deductible health plan is one that requires single enrollees to spend between $1,050 and $5,100 on health care (families must spend between $2,100 and $10,200) before insurance benefits kick in. What is a Health Savings Account? A Health Savings Account (HSA) allows consumers to save and invest pre-tax dollars that can later be withdrawn to pay medical expenses, such as co-payments and deductibles. Like other savings accounts, if the money isn’t used in a year, it can be rolled over and continue to compound and accrue. To open one, however, a consumer must be enrolled in a qualified high-deductible plan.
