I got mine at Walgreen's, not my Doctor's Office. I was surprised to get a bill from them, especially since I have a Plan F Supplemental through AARP United Healthcare with my Medicare. When I called UHC, they said they don't pay it, and upon checking with Medicare (after waiting 40 minutes on the phone), they told me that Medicare does not pay for the Shingles vaccine.
The Shingles vaccine (single dose) I received 8 years ago was paid by my Police Dept. Hospitalization Plan which was United Healthcare at that time. Why they (UHC) doesn't pay for it now is beyond me.
