Supplemental Medicare Coverage

No.  Only if you itemize.  But You can only deduct the amount of unreimbursed Medical Expenses you actually paid over 7.5% of your AGI.  And then all your itemized deductions have to be more than the standard deduction to get any benefit (so you would only be getting the benefit of the amount that puts you over the standard deduction).  And since the Standard Deduction is increased more people will not need to Itemize.

Thank you. I appreciate your assistance. 

the other possibility would be if you were self-employed. those that are can deduct it, but there rare limitations based on net SE income.
