You are not going to have a very easy time finding quality health insurance for young adults. It will sometimes seem the very best health insurance for young adults would be none at all...shocking but true. If you're a young adult (18 to 39 years old) and you are confident that you lead a pretty healthy lifestyle and you have a decent enough income that you are able to pay for going to the doctor or for OTC medications out of pocket, you may very well opt out of finding health insurance in the traditional sense of paying premiums for a policy. You just have to be willing to take your chances!
If you're a very young adult (18 to 26) in the United States you can now get an extension regulated by law that enables you to stay on your parents' health insurance policy. This means that for some extra money on their premiums your parents can keep you on their policy. It is true that this will bring forth some additional costs to your parents but it would never cost anywhere near the amount of money that would be required for you to buy your own health insurance when you are a young adult. There is an inordinate amount of young adults - even professional adults - living at home and they often are "stuck" living at home longer when in college due to increased and expanded credit loads required for graduation which makes this option most likely the best health insurance for young adults available. If you find that you could qualify for this type of health insurance for young adults, just remember that your parents may want you to be able to pay them the difference for what it costs to keep you on their policy.
If you're a working professional young adult who doesn't live at home (your parents' home), and you're healthy, you can opt for a high deductible health insurance plan. This keeps your premiums lower and the chances of your needing pay the deductible are low because of your youth and health. All 50 states have their own rules and regulations in terms of what is allowed and offered under this category so taking part in some further research could be required.
Health Insurance: Pregnancy an Maternity Health Insurance
If you're a young woman who still may, or expects to, become pregnant, you will want to make sure that you have coverage in your health insurance for maternity and pregnancy. This health insurance coverage takes care of your medical costs that you'll incur in the event you become pregnant. This coverage can be considered very helpful when you are a young adult woman because the enormous costs of a pregnancy - of OB-GYN visits, the delivery the baby, hospital stays, etc - the final tally could be in the $10,000 range.
If your pregnancy is a high risk one, you will probably find your pregnancy costs to be significantly more expensive. Insurance coverage of this nature should be available in this high risk scenario which will usually be an unforeseen one.
The American Pregnancy Association and the AmeriPlan service are designed to help individuals save money in health care services but be mindful of the fact these are not insurance plans or providers.
