As many consumers already know, health insurance providers are less likely to insure people with preexisting conditions. If you have been diagnosed with Heart disease in the past, it may be extremely difficult to obtain health insurance quotes. After being denied coverage from several providers, you may want to apply for a guaranteed issue insurance policy. These policies are designed to cover consumers with preexisting conditions. The downside is that most guaranteed policies will not cover costs associated the condition for a certain period after purchasing the policy. Fortunately, once the wait period is up, the guaranteed policy will begin offering more complete coverage.
