What's the difference between Medigap and Medicare Advantage?
Medigap supplements Original Medicare by covering some of its out-of-pocket costs, and you keep Original Medicare as your primary coverage. Medicare Advantage (Part C) replaces Original Medicare with a private plan that bundles hospital, medical, and often drug coverage — you generally can't have both at the same time.
When can I enroll in a Medigap plan without medical underwriting?
Your Medigap open enrollment period is generally a six-month window starting when you're 65 or older and first enrolled in Medicare Part B. During that window, insurers can't deny you coverage or charge more based on health. Outside that window, underwriting rules vary by state. {{VERIFY: state-specific Medigap underwriting rules}}.
