Short term or temporary health insurance is health insurance that just lasts for a certain period of time, typically 6-12 months but sometimes policies are as short as 30 days. Short term health insurance works the same as long term health insurance.
Depending on the policy, you will get a health insurance card and will have a deductible and limits on services. Although short term health insurance works the same as long term health insurance, one needs to realize that there is a major difference in coverage.
