Thanks for clarifying. If the FEHB premiums are paid with after-tax dollars for retirees (which I believe is the case), you premiums will be deductible. The above example sites the case for presently employed workers who have the premiums paid pre-tax.
Regarding the Medicare premiums:
Medicare A
If you are covered under social security (or if you are a government employee who paid Medicare tax), you are enrolled in Medicare A. The payroll tax paid for Medicare A is not a medical expense.
If you are not covered under social security (or were not a government employee who paid Medicare tax), you can voluntarily enroll in Medicare A. In this situation you can include the premiums you paid for Medicare A as a medical expense.
Medicare B
Medicare B is a supplemental medical insurance. Premiums you pay for Medicare B are a medical expense. Check the information you received from the Social Security Administration to find out your premium.
Medicare D
Medicare D is a voluntary prescription drug insurance program for persons with Medicare A or B. You can include as a medical expense premiums you pay for Medicare
