More than 10 million U.S. residents now have high-deductible, health savings account-compatible health coverage, according to America’s Health Insurance Plans.

About half of the HSA plan enrollees are in large, employer-sponsored plans, 30% are in small group plans, and 20% have individual policies, says AHIP, Washington.

In March 2005, 64% of the holders of HSA-compatible coverage were holders of individual health insurance policies, and only 19% were in large group plans.

AHIP reports wide variations in HSA plan enrollment at the state level.

Almost 14% of privately insured Vermont residents, and 9.2% of the privately insured residents of Colorado and Minnesota, have HSA-compatible coverage.

In Hawaii, just 0.2% of privately insured residents are eligible to open HSAs.
