Health insurance covers conditions that develop after your policy starts. Pre-existing conditions are typically not covered, and insurers may exclude related issues. Some policies may cover symptoms of pre-existing conditions under specific circumstances. Always review your policy's exclusions. Coverage for pre-existing medical conditions may be available if you currently hold a medical insurance policy or are transitioning from a company scheme. However, if you have never had medical insurance before or if your policy is not active at the moment, pre-existing conditions will not be covered. This limitation exists because health insurance is primarily intended to protect against unexpected health issues. To simplify, it's akin to getting into a car accident and then trying to obtain insurance coverage afterward to repair the vehicle — insurance companies typically do not cover such claims. Nevertheless, there is an option to gain coverage for pre-existing conditions after a two-year waiting period, subject to specific rules and conditions.
