What Is The Function Of Health Insurance? 
The purpose of health insurance is to protect yourself financially in the event of a catastrophic event . For example , if you have a health insurance plan and broke your leg and needed to have a $ 100,000 surgery , you may only be responsible for a few thousand dollars of it -LRB- e.g. your deductible or coinsurance -RRB- , as opposed to being responsible for paying the entire bill yourself . Many health plans will provide additional benefits as well , such as coverage for preventive care , routine doctor visits , prescription drugs , etc. .
