does your employer deduct the insurance premiums from your paycheck? then it's probable it has a plan where by your taxable wages are reduced by those premiums. If so, you already got a deduction so you can not deduct them again. If you mean you use the money from your pay to make payments to a company of your choosing then you would be entitled to a schedule A deduction. in this case there would be no box 12DD on your W-2. If you are unsure ask your employer.
