If you are a traveler, and you stay in other countries outside your home country quite a bit, you definitely need to have world health insurance.
You can get coverage for as long as you need it.
If you need it only for 6 months, that is fine.
If you need it for 3 years because you will be studying abroad, that is available also.
You can pay premiums monthly, quarterly, or annually.
Your basic coverage will be in-patient hospital stays, out-patient treatment, medical evacuation coverage for cases where there is not adequate care where you are located.
You can also get dental insurance, life insurance and maternity coverage as riders.
Don't assume that these are automatically covered.
They are usually not.
World medical insurance will cover you anywhere in the world you travel to.
Be sure to read all the details of your policy so that you are not surprised at a time that you can least handle a surprise.
World health insurance coverage is a portable health plan that will follow you wherever you go.
The reason to get world health insurance is because of the devastating costs of health care.
Health care is especially expensive if you need to be hospitalized.
In some countries the hospitals want to be paid right away, and want you to collect from the insurance company.
Most world health insurance companies will pay directly to the hospital or medical center though.
You just have to pay the initial deductible.
If you don't carry world insurance and you need medical care in another country, you can experience devastating financial problems.
With the coverage you can travel with the peace of mind that where ever you are, you have medical insurance coverage.
You do not have to worry about losing all your money due to an accident of illness while you are away from your native country.
