Since Medicare covers people over the age of 65, and those with certain disabilities that have received Social Security benefits for 25 months, it would be very rare for Medicare to cover a circumcision. It would be possible, if someone with Medicare had a true medical need to be circumcisized later in the life, but very rare, as most circumcisions are done at birth.
Given the fact that 40% of births in American are covered by Medicaid, a better question may be "Does Medicaid cover circumcisions?" That varies by state, as 18 states currently do not cover this procedure, primarily due to the fact that it is most often elective, or not necessary.
