BCBS told me that diarrhea and a stomach ache are pre existing conditions...a couple of years back I had my gull bladder removed...I had a bad stomach ache. Last year I was hospitalized for what the doctors called colitis and I had a form of diarrhea that had mucus in it and had stomach crapping for over a month...When I got my bill, BCBS covered nothing. They told me it was a pre existing condition. I have had doctors write reports telling them it can't be a pre existing condition because I no longer have a gull bladder. and that it has nothing to do with the gull bladder. Shouldn't I be covered? I appealed the claim twice and have been denied both times.
