Hi...sorry I do not have scoliosis or a syrinx, but I was wondering if you have leg issues and bowel issues...if so you may have tethered cord which could have caused the scoliosis.
Sorry your insurance is halting the investigation as to what is going on.....sometimes when you have a change in symptoms they (Dr) may be able to use a different code to get the INS to approve....it really depends on your Drs ability to get around the INS.
