Health coverage is essential, and the ACA Open Enrollment Period is your opportunity to review, renew, or enroll in a new health insurance plan for 2026. Whether you’re in Tucson or anywhere across Arizona, knowing the important dates can make the process easier and ensure you don’t miss out on the coverage you need.

At Meadowbrook Insurance, we understand that navigating health insurance can feel overwhelming. That’s why we’re here to help you plan ahead and make informed choices before the deadlines arrive.


🗓 Key ACA Open Enrollment Dates

  • November 1, 2025: First day to enroll, renew, or change your 2026 plan.

  • December 15, 2025: Deadline for coverage starting January 1, 2026.

  • January 15, 2026: Last day of open enrollment. Plans selected now begin February 1, 2026.


After January 15, you can only make changes if you qualify for a Special Enrollment Period (SEP) — typically due to major life events like marriage, the birth of a child, or loss of other coverage.

If you already have a plan, this is the perfect time to review your benefits, compare new options, and ensure your coverage still meets your needs and budget.
