Which statement about enrollment periods for Medicare Supplement Insurance is true?

The statement regarding enrollment periods for Medicare Supplement Insurance being limited to specific periods is true because Medicare Supplement Insurance, also known as Medigap, has designated enrollment windows. Specifically, there is an open enrollment period that begins when an individual is both 65 years old and enrolled in Medicare Part B. This six-month window is critical, as during this time, individuals cannot be denied coverage or charged higher premiums based on pre-existing health conditions.

Outside of this open enrollment period, individuals can still apply for Medigap coverage, but insurers may have the discretion to impose waiting periods for pre-existing conditions or to apply medical underwriting, which could result in higher premiums or outright denial of coverage based on health status. Therefore, understanding the limitations and designated periods for enrollment is essential for beneficiaries seeking Medigap policies.
