Catastrophic health insurance is a type of health insurance that provides coverage for unexpected, high-cost medical events. It is generally intended for individuals who are relatively healthy and do not require frequent medical care, but want to be protected in case of a major medical emergency. Catastrophic health insurance typically has lower monthly premiums than traditional health insurance plans, but also has higher deductibles and out-of-pocket expenses. This means that policyholders will be responsible for paying a significant portion of their medical expenses out of pocket before their insurance coverage kicks in. While catastrophic health insurance may not be suitable for everyone, it can be a good option for those who want to protect themselves against the financial impact of a major medical event.
