Wisconsin Health insurance premium deduction

My son works for an employer the provides health insurance.  He has an amount deducted for his portion of the premium from his bi-weekly check.  Is this premium deductible on Wisconsin return?   For myself my wife and I are on social security so there is the monthly medicare deduction.  My wife and I also pay a monthly premium for a medicare supplement.  Same question, are these premiums deductible?  Neither my, or my son's medical costs were not large enough to be deducted on fed return.  Hope this question makes sense.
