Short Term Medical plans are used to fill a short-term need for medical insurance. Occasionally, an employee will need medical insurance to cover him between jobs. Short-Term Medical is an inexpensive way to provide major medical benefits to protect against accidents or major illnesses that are not pre-existing. The benefit designs are basic, no-frills plans with little or no office or prescription co-pays. They are designed strictly to cover large claims that may occur during a lapse in other coverage.
