An estimated 1.3 million in the Houston area don't have health insurance, and as the second open enrollment period under the Affordable Health Care Act kicks in, the city of Houston, with the help of nonprofit groups, is trying to change that. For the next three-month open enrollment period, which starts Saturday and runs through February 15, Houston is relaunching its campaign to get people insured, with events and dedicated navigators to help people through the process. Local officials, including Mayor Annise Parker and Director of Houston Health and Human Services Stephen Williams, and State Senator Rodney Ellis gathered for an event at the Houston Public Library downtown on Friday morning. The group is called the Gulf Coast Health Insurance Marketplace Collaborative. "Just connecting someone to in-person assistance greatly increases the chance that they'll get enrolled," said Tiffany Hogue, policy director for the Texas Organizing Project, one of 18 government and nonprofit organizations working on the city's effort to enroll uninsured residents. Information is also available from staff at 14 health centers, multi-service centers and Women, Infant and Children (WIC) centers in the area.
