As far as I know a lot of funding has granted in collaboration with PCTs and Specialised Commissioning groups. And it is they who are 'billed' for your surgery. These groups have been in transistion for a while, and there will be further changes. But basically the SEGs will work with the new CCGs in the a similar way as they did with PCTs. There may be some disruption, but I think its highly unlikely that your funding will disappear.
