Life insurance is priced based on your life expectancy, the face amount you request and the length of the policy, whether it's the duration of your life (whole life) or a specific period (term life).

Because your current and past health conditions impact your life expectancy, insurers want to know as much as possible about your health condition. Common conditions such as high blood pressure, heart disease, obesity, cancer and depression can all raise your premiums or even result in a declination.

Based on your medical history, you'll be grouped into a category such as "preferred plus," "preferred," "standard" and "substandard." Your category ultimately determines your premiums.

Insurance buyers with severe health conditions or a combination of conditions can find it hard or impossible to find life insurance. They are known as "impaired risks." Local agents may not be experienced enough to find a company that specializes in insuring people with certain medical conditions. Fortunately, impaired-risk specialists have expertise in knowing where to direct applications for folks with medical conditions.
