What generally happens to premiums for individuals with serious pre-existing conditions?

Individuals with serious pre-existing conditions often face significantly increased premiums for their insurance policies. This is primarily due to the higher risk associated with covering individuals who have existing health issues that may require more frequent or costly medical care. Insurance providers assess the likelihood of needing to pay out claims and adjust premiums accordingly to mitigate their financial risk.

In many cases, when someone has a serious health condition, it indicates a greater probability of future health-related expenses. Consequently, to cover potential higher healthcare costs, insurers are likely to increase the premium rates substantially. This increase serves to balance the risk pool, ensuring that the insurer can maintain financial viability while still providing necessary coverage for higher-risk individuals.

As for the other choices: premiums typically do not remain the same or decrease for individuals with serious conditions, as those would not adequately reflect the elevated risk. While coverage might be eliminated in some cases, it's more common for insurers to offer coverage, albeit at a higher cost, rather than completely denying it.
