Sounds like it's all getting sorted, albeit a bit slower than normal, but at least it's one less thing to worry about at an already worrying time.The scheme is Fast Track (although I was told, "It's more like slow track at the moment"). It is virtually certain that the application will go through, but sometimes, clarification may be sought from the consultant making the application.
The beauty of Fast Track compared to regular CHC funding is that the ICB has no wriggle room. Their responsibilities are set out in the Standing Rules which are legally binding, as opposed to the National Framework which, as many on here will tell you, can turn out to be several years of battles.
Glad your mum is more comfortable and getting the care she deserves. At the end of the day that's the most important thing.
