0090T - Total disk arthroplasty (artificial disk), anterior approach, including diskectomy to prepare interspace (other than for decompression); single interspace, cervical
0091T - ... single interspace, lumbar
+0092T - ... each additional interspace (list separately in addition to code for primary procedure). Example: The surgeon performs total disk arthroplasty with placement of artificial disks at L2-3 and L3-4. In this case, you should report 0091T (for the initial lumbar interspace) and then code 0092T (for the additional lumbar interspace).
What about thoracic? No code describes thoracic disk arthroplasty, but this shouldn't be a problem - at least not for now.
"No companies have pursued thoracic disk arthroplasty for three reasons," says Kee D. Kim, MD, associate professor at the University of California at Davis in Sacramento. "Thoracic disk herniation is very rare, preserving motion in thoracic spine is not that important since there is little motion to begin with, and the approach to thoracic spine carries high risk." 0093T-0098T Describe Removals and Revisions Along with the placement codes, you'll also have three codes to describe removal of artificial disks and three codes to describe revisions: 0093T - Removal of total disk arthroplasty, anterior approach; single interspace, cervical
0094T - ... single interspace, lumbar
+0095T - ... each additional interspace (list separately in addition to code for primary procedure)
0096T - Revision of total disk arthroplasty, anterior approach; single interspace, cervical
0097T - ... single interspace, lumbar
+ 0098T - ... each additional interspace (list separately in addition to code for primary procedure).
Don't report both removal and revision: When the surgeon removes and then replaces previously inserted artificial disks, you can report only the revision codes. Parenthetical references following the revision codes specifically state, "Do not report 0096T with 0093T," "Do not report 0097T with 0094T" and "Do not report 0098T with 0095T."
Translation: If the surgeon removes previously inserted artificial disks and then performs spinal fusion, for example, you should report the appropriate removal [...]
