Does most health insurance companies provide insurance to injuries that Occurred before having insurance?

Usually not preexisting injuries, but if you had a disease they would. such as Diabetes.

Answer

Group insurance policies can only exclude preexisting conditions for 12 months, 18 months for a late enrollee. And not at all if you have prior "creditable" coverage. For more info use this link: http://mtnhealthinsurance.com/index.php?pageName=sec9801

In most states you are not going to be able to obtain individual (non group) coverage with a preexisting condition.
