Supplemental Insurance is no different than a typical policy. The difference is that it gives you coverage for medical expenses not covered by your primary insurance. It can be used as an added protection to help make sure you’re covered when the worst can happen. Hospitalization coverage is available for unlimited days and protects you against million-dollar expenses for things like hip or knee replacements, heart bypass surgery and kidney dialysis. Cancer coverage can help pay for treatment like chemotherapy or radiation therapy, and critical illness coverage will cover things like coronary artery bypass surgery and total hip replacement. Plans are customizable so you get exactly what suits your needs.
