The USA offers possibly the finest health care in the world. The problem is that, unless you have good insurance, it can be prohibitively expensive. It’s essential to purchase travel health insurance if your regular policy doesn’t cover you when you’re abroad.
Bring any medications you may need in their original containers, clearly labeled. A signed, dated letter from your physician that describes all medical conditions and medications, including generic names, is also a good idea.
If your health insurance does not cover you for medical expenses abroad, consider supplemental insurance. Find out in advance if your insurance plan will make payments directly to providers or reimburse you later for overseas health expenditures
