Frequently Asked Questions

Q: Can I change plans after open enrollment ends? A: Only with a qualifying life event (marriage, birth, job loss) that triggers a Special Enrollment Period, or during your renewal period next year.

Q: What happens if I miss the deadline? A: You may have to wait until the next open enrollment period unless you qualify for a Special Enrollment Period or Medicaid/CHIP enrollment (available year-round).

Q: How do I know if my doctors are in-network? A: Check the insurance company's provider directory, call the doctor's office directly, and verify hospital affiliations. Always confirm before enrollment.

Q: Can I have two health insurance plans? A: Yes, you can have multiple plans. Coordination of benefits rules determine which pays first. This might occur with spousal coverage or Medicare with supplemental insurance.

Q: Is short-term health insurance a good alternative? A: Short-term plans don't cover pre-existing conditions, essential health benefits, or qualify as minimum essential coverage. They're temporary solutions, not replacements for comprehensive coverage.
