KSL TV 5PM: Utahns have another chance to enroll in Affordable Care Act marketplace KSL TV SALT LAKE CITY — Utahns who missed open enrollment for the federal Affordable Care Act marketplace have a second chance. Normally, sign-up is just once a year. The federal exchange website reopened sign-ups for another three months, giving uninsured Americans plenty of time to explore health insurance options. "This is an open door for anyone who is uninsured or underinsured," Stanford explained to KSL-TV. "If you're currently in an aca plan and you want to make changes, this is a really wide open enrollment period."
