What is a pre-existing condition in health insurance?

A pre-existing condition means that the insured had a medical condition, or a disease, before taking the health insurance policy. For instance, a policyholder having a health problem such as diabetes, asthma, or cancer before their new health insurance plan becomes active is known as a pre-existing condition.

For those of you thinking about whether insurance companies can refuse you in case of a pre-existing condition, you have nothing to worry about. As per the current law, health insurance companies cannot refuse to provide insurance plans to someone with pre-existing conditions or even charge more for their policies.
