The main ways that mental health affects life insurance are coverage limits and price. When you apply for coverage, the underwriter will ask questions about your specific disorder, including how long you have had the disorder, how severe it is and what your treatment plan is like (if you have one).
Because mental health disorders are a pre-existing condition, you might pay more for life insurance if you have been diagnosed with a condition like depression or anxiety. In addition, if your illness is severe or if you are not getting treatment, it might limit the amount of coverage you are eligible for.
