The "liabiliy release" doesn't affect your health insurance-only whether you can sue your employer or collect comp. Health insurance pays for an injury regardless of your or anyone else's liability for it.

As to the preexisiting condition clause, most of this problem was eliminated by HIPPA if the injury occured while you were covered under another policy and there was no break in coverage b/w your prior policy and your current one.
