ACA Open Enrollment 2027: Key Dates for Katy, Dallas, San Antonio & Oklahoma City

Open enrollment for ACA Marketplace (Obamacare) plans runs from November 1 through January 15. If you want your coverage to start January 1, apply by December 15. Enrollments made between December 16 and January 15 usually start February 1.

Texas did not expand Medicaid, so for many lower-income adults and anyone with a pre-existing condition, the Marketplace is often the only realistic option. Marketplace plans cannot deny you or charge you more because of your health history.

Before you pick a plan, check three things: whether your doctors and hospital are in the network, whether your prescriptions are covered, and how much tax-credit help your household income qualifies for.
