Hi Linda
The assessor can request additional information that is why they ask you for details of your doctor or any specialist who is treating you for a prognosis.
Appeals can take a long time to get a hearing date depending on where you live, although on the forum we have heard from members where it has taken only a few weeks. The last one I did took 8 weeks from submitting the appeal online to getting a decision, so it does vary.
I have attended Tribunals where it has been adjourned as the Chair wanted to see the claimants medical file, the claimant suffered from epilepsy, the chair received over 200 pages of medical evidence, we were awarded standard rate for both components.
The claimant had tried 3 times by themselves to apply for PIP and was going to give up when I got involved.
