In my opinion, and as far as my patients are concerned, the price.
According to Axiom Worldwide, the makers of the DRX9000TM, their machine and their machine alone offer "true spinal decompression"; and technically, they are completely correct. The reason I don't dispute this is because the manufacturer of the DRX9000TM machine obviously has a brilliant marketing department; they actually named the machine the "DRX9000TM True Spinal DecompressionTM System". This full "name" rarely goes unmentioned on any advertisement for the machine.
Nevertheless, as far as the FDA's "classification" and "common name" for both machines is concerned, they are the same for the DRX9000TM, http://www.fda.gov/cdrh/pdf6/K060735.pdf , as they are for the Triton® DTS, http://www.fda.gov/cdrh/pdf5/K053223.pdf. This is one of the main points I based my decision on to purchase the Triton® DTS over the DRX9000TM.
Granted the DRX9000TM is gorgeous and it comes with all kinds of awesome bells and whistles. It also comes with a tremendous price tag. The Triton® DTS costs 1/10th of what the DRX9000TM does. However, when I chose the Triton® DTS over the DRX9000TM, it wasn't because of what it would cost me, but rather what it would cost my patients. I prefer to find ways to offer services for a reasonable fee than be forced to charge thousands and thousands of dollars, in ADVANCE?!?, to cover the cost of my overhead. Again, my opinion.
For most patients we recommend 18-20 sessions; daily for the first week and 3x/week for the next four weeks . The cost per session is $45.00; $800-900 for the whole series. Insurance does cover this service when it is billed correctly as mechanical traction (CPT 97012), not as the experimental code of S9090. Patients may pay as they go on each day of service. If they prefer, patients may pay for the whole series in advance and we will apply a 10% pre-payment discount. We offer treatment for both the cervical or lumbar, the price is the same.
