Not necessarily. You should check these policies before you travel to assess exactly how or if you would be covered in case you have an emergency.
Credit cards and homeowner's policies. Many credit cards and homeowner's policies don't cover everything you need to protect, including some types of emergencies and trip cancellation or interruption. If they do provide coverage, it's often limited, depending on the type of card you use or the coverage you have with your homeowner's policy.
Health insurance. Most health insurance plans don't provide direct payment to foreign hospitals. They may also have deductibles and won't cover the cost of emergency medical transportation.
Additionally, travel insurance can provide you with a wide range of assistance benefits, even if you're traveling halfway around the world. You can find out more about these benefits in the question below.
