Found it on Medicare Interactive . gov
Couldn't copy and past from the doc, but see the bottom of pg 8, item # 6, "you have an SEP if..... "You want to disenroll from your FIRST Medicare private health plan (MA)" Link Here
Says you can disenroll from MA at any time during your first year and go back to Orig Med, with or w/o joining a stand alone PDP. It does not however, specifically state that you are GI to a Med Supp. Hmmmmm, one would think that you would have this option unless it has escaped the oversight of the regime, aka CMS/HHS.
