Turmoil in the commercial individual major medical insurance market may be hurting people's ability to get private coverage.
The number of people with individual coverage fell 3% between the end of 2015 and the end of 2016, to 17.3 million, according to Mark Farrah Associates.
That compares with 5.8% growth in individual health enrollment between 2014 and 2015.

The individual enrollment figures include people who bought their coverage through the Affordable Care Act public exchange system and people who bought their coverage outside the exchange system.
"The volatility of the Affordable Care Act's exchange program forced many insurers to dramatically raise premiums in order to make up for financial losses, or to withdraw from the exchanges altogether, negatively impacting membership," according to Mark Farrah analysts. "Needless to say, the market outlook is uncertain."
