If you have a long-term health problem while on short-term health insurance, what happens when it expires?

For example, let's say you purchase a short-term health insurance plan with a duration of 6 months. Then, 3 months from now, something goes wrong that will require treatment for many months or years (cancer, liver problems, a bad accident, etc). Will the short-term health insurance plan only pay for your treatments for the remaining 3 months until the policy is set to expire? Or, since the health problem occurred while the plan was in effect, are treatments covered indefinitely (up until the lifetime maximum dollar amount is met)?

You have to contact the insurance provider. It varies from policy to policy but you can bet they won't want to spend a penny more than they must. The Muse
