High-deductible health plans (HDHPs) have only increased in popularity over the past several years. According to a recent report from ValuePenguin, a record 55% of Americans enrolled in HDHPs in 2021. That's an 83.7% increase over seven years, from 30.3% in 2013. Many employers might prefer HDHPs over other insurance options because the premium costs are lower, suggests ValuePenguin health insurance expert Divya Sangameshwar. However, HDHPs can become prohibitively expensive for lower-income workers, particularly those with chronic conditions and whose employers don't also provide health savings plan contributions. Nevertheless, with health care costs expected to rise in 2023, HDHPs are likely to be the plans of choice for many Americans—and a new report shows just where those plans are currently the most popular among private-sector employees. The report, funded by the Robert Wood Johnson Foundation, uses data from the State Health Access Data Assistance Center at the University of Minnesota. For the purposes of the report, a high deductible health plan is defined as a plan that meets the minimum deductible amount required for a Health Savings Account (HSA). In 2021, that amount was $1,400 for an individual and $2,800 for a family.
