Putting this out there so anyone who has challenges getting things approved - this is what I found out today. BCBS did not deny but it was the 3rd party they use that denied my petscan. BCBS connected me to them and I explained my whole story - she said the dr did not even do a peer to peer with them. She said most likely they (3rd party) want more information like blood tests. She gave me their direct# and case ref# and I gave them back to the doctors nurse and asked them to make this happen. Perhaps the dr is so busy and did not take the time - I do not know but that is a bit frustrating. The response I got back was the skeletal CT scan sb sufficient along with the bone marrow biopsy.....but what I see on the web from Sloan Kettering Hospital and Cleveland Clinic and Mayo as well - is that the petscan is an integral part along with the BMB because it is possible that the spot they pull the biopsy from may not have the bad cells in that spot which is why a petscan is also needed as it sees all of the bones on in the inside. The skeletal CT shows if any lesions are on the bones on the outside.....SO. I have asked the doctors office to push this today as my insurance changes 8/1 and I need to know what I am dealing with. QUESTION - Am I being unreasonable....
