Getting so discouraged

Has anyone here recently, in the past 2 years, been approved for a second wls (after lap band removal) with Medicare?  I was getting everything set up, purchased a BCN plan in the Marketplace (Obamacare) as a second policy and thought I was homefree.  Then, my Medicare card shows up in the mail. I am in my 50's but on disability for spine issues so that made me eligible.  then I find out BCN wouldn't have approved me anyway because of the once in a lifetime clause.

I really need to hear something GOOD for a change.  I am set to have the band removed, have a date and approval thru BCN.  But I have to be on Medicare in August so they are my only saving grace.

Now I am finding out that I am probably going to have trouble with Medicare for the same reason.
