While it's true that the costs for health insurance coverage continue to increase, having a health insurance plan will save you more money in the long run. But no health insurance plan will cover every medical treatment an insured individual needs over the course of his or her coverage period. No matter how good your health insurance is, you may occasionally encounter a medical treatment or condition that is not covered by your health insurance policy. Although these situations are normally confined to elective treatments like cosmetic surgery and liposuction, that is not always the case.
