Many Republicans, including President Donald Trump, say they want to replace the Affordable Care Act health insurance system with a new system that will rely more heavily on health savings accounts.
In 2016, however, with the ACA system still in effect, health insurers had a hard time increasing sales of HSA-compatible coverage.
The participating carriers said they covered 20.2 million U.S. residents through HSA-compatible, individual, small-group or large-group plans in 2016.
The number of people with HSA-compatible coverage was just 2.4 percent higher than in 2015.
Between 2014 and 2015, enrollment in HSA-compatible coverage grew 3.6 percent.
AHIP also reported data implying that the number of insurers in the HSA-compatible plan market might be falling.
The Washington-based trade group has recorded a drop in the number of issuers participating in its survey every year from 2012 through 2015. The number dropped again in 2016. Just 59 issuers filled out survey forms for 2016. The issuer count was down 7.8 percent, from 64, in 2015. In 2012, 95 issuers filled out survey forms.
AHIP believes that a total of 97 issuers were selling HSA-compatible coverage in 2016. The number of known HSA plan issuers was down from 109 in 2015, and down from 113 in 2014.
An AHIP representative said the organization believes the decline in the number of survey participants is mainly a result of survey participation issues and does not reflect a decline in insurer activity in the HSA-compatible plan market.
