Why can't I enroll in health coverage whenever I want?

Health insurance providers offer open enrollment periods to avoid people enrolling in a plan only when they're sick and then dropping it when they are healthy. If this were the case, there wouldn't be enough healthy people paying premiums to cover the medical costs of individuals when they are sick.

How Do Open Enrollment Periods Vary?

Open enrollment periods often vary based on the type of coverage offered. The classifications of coverage with different open enrollment periods are as follows:

  • ACA Marketplace: Annual enrollment periods span from November 1st to January 15th.
  • Medicare: Annual enrollment periods are typically from October 15th - December 7th.
  • Medicare Advantage: annual enrollment spans from January 1st - March 31st.
  • Employer-Sponsored: Open enrollment is set by the employer.

Can I Make Changes to my Coverage Outside of Open Enrollment?

  • Adopting a child
  • Becoming a U.S. citizen
  • Changing income
  • Getting married
