Summary: Amends part D of title XVIII (Medicare) of the Social Security Act to: (1) extend the 2006 and 2007 initial enrollment periods for the Medicare prescription drug benefit, (2) suspend the late enrollment penalty through December 31, 2007. And (3) permit Medicare beneficiaries to change enrollment in a prescription drug plan during the first 12 months of enrollment.
