Not all credit cards include coverage trip cancellation or trip interruption. Even some that do require you to buy-in to it. Credit card coverage often isn't as comprehensive for trip cancellation, trip interruption, travel medical expenses, and emergency medical transportation. And it typically doesn't include coverage for pre-existing conditions or if the travel supplier falls into bankruptcy or financial default.
Check to see if your credit card is this comprehensive. If so, you may just feel comfortable supplementing that coverage with a travel medical-only plan.
