What is meant by "pre-existing condition" in health insurance?

A "pre-existing condition" in health insurance refers to a health issue that existed prior to the issuance of an insurance policy. This means that if a person was diagnosed with a particular medical condition before obtaining their health insurance, that condition is categorized as pre-existing. These conditions are significant in the context of health insurance because insurers often assess the risks associated with covering individuals with such conditions. As a result, many insurance plans may have exclusions or waiting periods regarding coverage for treatments related to pre-existing conditions. This is a vital aspect for policyholders to understand, especially when considering coverage options or seeking care for their existing health issues.
