The Medigap Open Enrollment Period is a six-month period that begins when a Medicare beneficiary is both 65 years old or older and enrolled in Medicare Part B. During this period, beneficiaries have guaranteed issue rights, meaning they can enroll in any Medigap policy sold in their state without being subject to medical underwriting. This means insurance companies cannot deny coverage, charge higher premiums, or impose waiting periods based on the beneficiary’s health status or pre-existing conditions. The Medigap Open Enrollment Period is the best time for beneficiaries to purchase a Medigap policy because they have the most flexibility and protection against insurance denials or higher costs. Missing this enrollment period may result in limited options and higher premiums. It’s important for beneficiaries to take advantage of their Medigap Open Enrollment Period to secure the coverage they need for their healthcare expenses.
