  • Students have special rules for temporary moves

Marketplace-Specific SEPs

Plan Year Changes:

  • If you move outside your plan's service area
  • If your plan substantially violates network adequacy standards

Cost-Related Changes:

  • If you gain or lose access to other qualifying coverage
  • If you become newly eligible for advanced premium tax credits

Common Mistakes to Avoid

Missing the Deadline:

  • Mark your calendar with the 60-day deadline
  • Don't wait — plans can take time to research
  • Some life events have shorter deadlines (like employer plans)

Not Having Documentation Ready:

  • Gather required documents before starting the enrollment process
  • Keep copies of everything
  • Some documents (like birth certificates) can take time to obtain

Not Understanding Effective Dates:

  • Coverage doesn't start immediately
  • Plan for gaps in coverage
  • Consider short-term coverage if needed

Assuming You Don't Qualify:

  • Many life events qualify that people don't realize
  • Contact Healthcare.gov or a navigator if unsure
  • It's better to apply and be told you don't qualify than to miss the opportunity

Pro Tips:

  • Set reminders for the 60-day deadline
  • Consider if your current plan still meets your needs after the life change
  • Don't just pick the same plan — shop around for better options
  • If you're unsure whether you qualify, apply anyway — the worst they can say is no
