How do health plan enrollment periods work?

Health insurance can be complicated. To start your journey, think about which group of statements below best describes you.

Medicare Annual Enrollment Period

The Medicare Annual Enrollment Period (also called AEP) is every year from October 15th to December 7th. It’s a time when people getting Medicare can make changes to their coverage. 

The AEP enrollment window applies to Original Medicare, Medicare Advantage, and Medicare-Medicaid (D-SNP) coverage.

Look into finding a health plan during the Medicare Annual Enrollment Period if the following describes you:

• I am 65 or about to turn 65.

• I currently have Medicare, or a Medicare-Medicaid (D-SNP) plan.

• I’m under 65, but have a disability that keeps me from working.

Open Enrollment for Medicaid

If you’re a member of a Medicaid plan, or think you may be eligible for Medicaid, enrollment works a little differently.

• You can enroll in a Medicaid health plan at any time of year, as long as you’re eligible.

• Your child may qualify for the Children’s Health Insurance Program (CHIP), even if you don’t qualify for Medicaid.

Make sure to double-check your Medicaid eligibility before December 31st! The requirements can change each year.

Open Enrollment Period

If you aren’t eligible for Medicare or Medicaid, Open Enrollment is the only time of year you can get health coverage without a qualifying event. (Check the FAQ to learn about qualifying events.)

The Open Enrollment Period is every year from November 15th to December 31st. This is a time when people can look for health plans on their state’s Health Insurance Marketplace.

Look into finding a health plan during the Open Enrollment Period if the following describes you:

• I am 18 to 64, and do not have a disability that keeps me from working.

• I don’t get health insurance through my employer.

• I don’t qualify for Medicaid.

Some questions to ask yourself as you look for coverage:

  • • Are the providers I want to see in-network?
  • • Are my prescriptions covered?
  • • How often do I expect I’ll need healthcare services next year? Are my needs going to change, or stay the same?
  • • What additional benefits, if any, do I need?
