It's more probable, due to the timing of the cxbladder launch, that PEB are working through a specific process within CMS. Thus, while discussions and final accreditation is ongoing, PEB remain a medicare provider with a final commercial agreement governed by the legislative changes pending.
With PEB having been a Medicare provider for six months now, it does seem to put that anticipated 'tens of thousands of tests in 2014' advice from Chris Swann into some perspective.
