Limited indemnity health insurance covers the essentials: emergency treatment and hospitalization. Unlike other types of health insurance, there are no limitations on which doctors, specialists, or hospitals you can visit. The downside is that you will be responsible for a significant co-insurance percentage of those costs (after the deductible that must be paid up front before coverage kicks in), which tends to be high), and you will often need to file claims yourself.
It is far less comprehensive than major medical coverage. For example, preventative care services may not be included. However, it is far less expensive on a monthly basis, and will protect against financial hardship due to serious health issues. As a result, limited indemnity coverage is best for those who are healthy and relatively young, yet have a tight budget. Many student health insurance options are limited indemnity plans.
