We went through every level of appeal with the snipet test and last Thursday I participated in the last level of appeals...an appeal panel. Three people with no prior knowledge of the case read her whole file pertaining to this test. My participation in this panel was to state further information and reasons why this test should be covered, as well as to answer any questions the panelists might have.
Today I received the decision letter from the panel and they are approving and covering the genetic snipet test from December! We don't know how much of the test will be covered, or what our expense will be, but this is still a win!
I would like to add that we did not discuss the full genome sequencing test during this panel. We still have a few levels of appeal available to us with that test, and the panelists did not want us to lose those appeal levels by considering it with the snipet test.
