LOVELY - I have been denied insurance coverage

[DeposeTheBoyKing]

My insurance from my job lapsed, and I didn't do the COBRA thing. (I didn't return to work after a 3-month absence for herniated discs, but would have been laid off anyway had I returned). We applied to have me added to my husband's insurance during the open enrollment month. However, I got a denial letter today. No reason given, but I suspect it was due to the back problem. I also have high cholesterol which is being treated, as well as hypothyroidism, also under treatment. I can appeal, but do I really have a chance of success? I thought about contacting my orthopaedic surgeon who treated my back problem to see if he can write a letter on my behalf Naturally it's Friday afternoon and the office is closed, it being 5:11 now.

I don't like being without insurance. I feel I have to drive very, very carefully to avoid accidents and just hope nothing happens to me. Does anyone have any experience with this?
