If you didn’t have Parkinson’s when you took out your life insurance policy, and were diagnosed during the policy term, then your life insurance will cover death caused by the disease or related causes.
If you had Parkinson’s when you applied for your life insurance policy, this counts as a pre-existing medical condition which must be disclosed on your application.
Your insurer may either: accept the application and insure you to include Parkinson’s cover, include an exclusion for Parkinson’s, meaning death as a result of the disease itself or any specified related conditions won’t be covered, or decline your application.
Whether you’re covered for Parkinson’s will be stipulated in your policy.
From our experience, most insurers will provide cover for the disease if they accept your application rather than apply an exclusion, but you will pay a higher premium for the cover.
