Frequently Asked Questions
When should I enroll to avoid a gap?
Enroll during the 3 months before your birthday month — then your coverage can start the first day of your birthday month, with no gap.
What if I miss my Initial Enrollment Period?
You may qualify for a penalty-free Special Enrollment Period (e.g., if you had employer coverage). Otherwise you’d use the General Enrollment Period and may owe a late penalty.
