Health insurance with pre-existing diseases financially shields individuals with pre-existing medical conditions like diabetes or hypertension. It is crucial to understand this type of insurance as it often comes with specific terms and waiting periods.
A waiting period is the time after purchasing a health insurance plan when you are unable to submit claims for a pre-existing condition. Let us understand what are the pre-existing diseases and their waiting period are covered by major insurers.
A pre-existing disease (PED) refers to any illness, disease, or medical condition that you had before purchasing a health insurance policy. This chronic disease health insurance in India includes conditions like diabetes, asthma, hypertension, thyroid disorders, and so on.
Health insurers typically impose a waiting period before covering such conditions, which means you cannot claim expenses related to the PED during that time. Declaring pre-existing conditions honestly is vital to avoid claim rejection later.
The waiting period for pre-existing diseases in health insurance varies by insurer, typically ranging from two to four years. During this period, any claims related to pre-existing conditions will not be covered. Once the waiting period ends, the policy will cover these conditions.
It is important to check the waiting period details in your policy to avoid surprises during a claim.
