Tomorrow is the end of a grace period for certain people who are eligible for subsidized health insurance but haven't yet signed up.

Arizonans who were "in line" to get coverage by midnight, March 31, 2014 on the website has until tomorrow - April 15 — to complete the process.

You might not have finished enrolling in time for reasons like these:

- You couldn’t start or continue your application because of heavy traffic to or the Marketplace call center

-You encountered maintenance periods that kept you from using the site

-You were blocked by error screens or similar technical issues

-You tried to get an appointment with a navigator or other application assister but they had no times available before the deadline. Or you were working with an assister but didn't finish enrolling in time.

-You sent in an application by mail and didn’t get an eligibility result before the deadline

Federal officials offer the following instructions to people who didn’t finish enrolling for reasons like the ones above:

Log onto and continue the enrollment process. Pick up where you left off. Before you finish enrolling, you’ll see a statement that you tried to enroll before March 31 and didn’t finish. If you continue past that point, you’re confirming that statement.

Or contact the Marketplace Call Center. Be sure to tell the customer service representative that you tried to enroll before March 31. They can help you finish enrolling by phone. Call 1-800-318-2596 (TTY: 1-855-889-4325) 24 hours a day, 7 days a week.

You must finish your enrollment by April 15 to get coverage for 2014. If you enroll by April 15, your coverage will begin May 1.

If you enroll this way and your coverage begins May 1, you won’t need to pay the uninsured penalty for the months of 2014 that you didn’t have health coverage.
