When to Enroll in Medigap in Charleston
Your Medigap Open Enrollment Period is the 6 months after you turn 65 AND enroll in Part B. During this window, insurers cannot deny you coverage or charge more due to health conditions.
If you miss this window, you may need to pass medical underwriting to get Medigap coverage. South Carolina has not expanded Medicaid, making Medigap timing especially important.
We help Charleston residents understand their enrollment window and make timely decisions.
