Medical insurance premiums are paid pretax when purchased from my employer.  When I retire (quit my job), prior to medicare age, are medical insurance premiums pre-tax?

Out-of-pocket medical insurance premiums are eligible to be included with other qualifying medical expenses as an itemized deduction above 7.5% of your adjusted gross income.
