Why Are Insurance Companies Allowed To Deny Coverage Of Life Saving Procedures Because It’s Cost Effective?

I am not sure that I am totally for universal health care.
However I do think something needs to be done about private insurance companies denying life saving procedures because of cost and this causing the consumer to either #1. Bankrupt themselves trying to cover the cost themselves. OR #2. Die.
There have been insurance company supervisors who have testified before Congress that they have made these decisions and the insurance companies have pressured them into making these decisions more and more.
Do you think this is acceptable?
