Auto-Reenrollment

Auto-reenrollment is the process by which your ACA Marketplace health insurance plan automatically renews for the following year if you don’t actively make changes during Open Enrollment. If you take no action, the Marketplace will re-enroll you in your current plan (or a similar one if your plan is discontinued) and recalculate your Premium Tax Credit based on projected income.

Auto-reenrollment is convenient, but relying on it without reviewing your options carries real risks:

  • Premium changes: Your plan’s premium may have increased significantly. Your auto-renewed subsidy may not fully offset the increase.
  • Network changes: Your doctors or specialists may no longer be in-network under your renewed plan.
  • Formulary changes: Medications you take may have moved to a higher cost tier or been removed from coverage.
  • Income changes: If your income changed, your subsidy may be wrong — leading to a repayment at tax time or leaving money on the table.
  • Better plans available: New plan options may have entered your market that offer better value for your situation.

The best practice is to actively log in to your Marketplace account each Open Enrollment, review your options, and confirm your enrollment rather than allowing auto-reenrollment to take effect passively.

Frequently Asked Questions

Will my coverage lapse if I forget to renew during Open Enrollment?

Yes, if you’re enrolled in a Marketplace plan and don’t make changes during Open Enrollment, you’ll be auto-enrolled for the new year. Your coverage won’t lapse. However, the plan you’re auto-enrolled into may have different premiums, networks, or drug coverage than your current plan — which is why reviewing your options each year matters even if you plan to keep the same coverage.

Does auto-reenrollment apply to Medicaid?

Auto-reenrollment doesn’t apply to Medicaid — Medicaid uses an annual redetermination process where your eligibility is re-verified. If you miss redetermination, your Medicaid coverage can be terminated. The auto-renewal process described here applies specifically to ACA Marketplace (private) plans.
