Another problem may be shaping up for the Golden State's answer to the federal health care law.
According to the San Jose Mercury News, 15 percent of people in the Covered California program have not made their first month's payment.
The state's health care exchanges said they are trying to bill those enrollees via e-mail and by phone. These people could lose their insurance if they do not pay.
Last December, the health plans agreed to extend payment deadlines when they ran into huge numbers of applications piling up.
For people who don't have insurance right now in California, the deadline to sign up is March 31 or pay a penalty.
