Health insurance is essential for protecting the wealth of high-net-worth individuals against significant losses due to illness. It allows access to top medical care and preserves net worth. High-limit disability insurance is recommended, offering up to $150,000 monthly, compared to standard policies that provide only $10,000. Critical illness insurance pays a lump sum for treatment costs, while long-term care insurance covers medical and non-medical services for seniors. As wealth increases, the need for comprehensive health coverage becomes more critical to safeguard assets.
