Medicare part B does NOT cover shingles vaccination. Part D covers it as a prescription drug (even though it is a preventive vaccine). If your Medicare advantage plan covers part D (drugs) then the shingles vaccine is covered. Your copay may vary from plan to plan. CDC determines the cost of the vaccine including the administration fee is around $190 (2013 price). The copay one has to pay may vary from $60 to 80 to 100. If you have a Medigap (supplemental coverage) policy you may avoid the copay also. Check with your Medigap policy administrator.
