 @Html.TextBoxFor(m => m.IDnumber, new { @class = "form-control", id = "txtIdNumber" })
 @Html.ValidationMessageFor(m => m.IDnumber)

Why you need to have IsMedicalInsurance to be nullable since the value is either true of false and shouldn't be null? I have try your code and it is working with IsMedicalInsurance change to bool instead of bool
