Killeen's county & enrollment timing

A few practical details shape shopping for coverage in Killeen: which county you're in, and when you can actually enroll.

Open Enrollment for ACA Marketplace plans in Killeen runs November 1 into January each year. Note: a 2026 court ruling that would end Open Enrollment on December 15 is under appeal, so confirm the current closing date on HealthCare.gov (we track the case on our news & updates page). Outside that window, a job loss, a move, marriage, or the birth of a child opens a 60-day Special Enrollment Period to enroll without waiting for the next Open Enrollment. Medicare beneficiaries in Killeen have their own separate windows — see our Medicare Advantage guide for the specific dates.
