Upcoming hearing

I have a hearing coming up in March. I have waited for a long time for this, and am very anxious about what may happen. While reviewing my denial I realized that they initially left off my inflammatory arthritis, which is my major physical illness. They had me listed as severe for fibromyalgia, which was listed later in the claim. How can they just pick and choose what they decide to rate and ignore your diagnosis listed as your primary issues? Also, I’m reading of people having hearings scheduled and then upon review they are cancelled because the files have been reviewed and approved prior to the hearing. How often does that happen? Does that have to be requested or is it automatically done? Thank you.
