Medigap
The Medigap open enrollment period is unique to each person because it’s tied to the time around the 65th birthday. Enrollment starts the first month with Medicare Part B or on the 65th birthday and lasts for six months.
During this time, companies can’t consider any current health or medical history or deny coverage based on health. Outside of this period, you may be subject to higher costs or denials.
