The Kaiser Family Foundation conducts an annual survey of employer-sponsored health plans. According to the 2012 survey, one-third (31 percent) of firms that offer health coverage offers a consumer driven health plan (CDHC) option. Approximately one-in five covered workers are in CDHC plan. Eleven percent of covered workers are in a Health Savings Account-qualified (HSA) plan in 2012 — up from 9% in 2011; while 8% are in an HRA plan in 2012 — about the same as in 2011.
About 149 million people are covered through an employer health plan. The report didn’t break down HSAs/HRAs by the number of people enrolled. But the data suggests that as many as 28 million people may be in an employer HRA/HSA plan.
