The Student Injury and Sickness Insurance Plan is a one-year term policy. The premium rates and coverage dates are set and cannot be changed or pro-rated out further. Each year the premium rates and benefits may change. Premium rates usually increase each year due to inflation as well as the rising cost of health care. William & Mary and UnitedHealthcare StudentResources both work hard to offer the highest level of benefits at a competitively priced premium rate. See below for the premium rates for each policy year.
