<human>:  I'm having trouble understanding the different types of insurance coverage. Can you help me understand the basics of health insurance?
<bot>: Health insurance is designed to help protect you financially against the cost of medical care. Generally, it covers all of your medical expenses, including hospital stay, doctor's office visits, prescription medication, and home care. It may also cover preventive care, such as routine check-ups, vaccinations, and mental health services. Depending on the plan you choose, it may also provide coverage for operations and specialty services like radiation therapy. Different plans may also offer different levels of coverage, so it's important to research and compare plans to make sure you understand the types of coverage offered by each.
