Can someone please help me with coding this procedure. The only code I know to use is the 22612 but I need help with the others. Any help is greatly appreciated.
PROCEDURES PERFORMED:
1. L3-4 interspinous decompression and fusion arthrodesis using
ASPEN LANX interspinous device as well as locally harvested
bone autograft, bone allograft sponge and iliac crest bone
marrow stem cells as well as demineralized bone matrix.
2. L3-4 bilateral posterolateral arthrodeses from transverse
process to transverse process using again local bone autograft,
iliac crest bone marrow stem cells and bone allograft as well as
demineralized bone matrix.
3. L3-4 right-sided laminotomy, medial facetectomy and foraminotomy
with right L3 and L4 nerve root decompression. :confused:

I am not really familiar with the ASPEN LANX device, so I would pose two scenarios and ask your physician. If the ASPEN LANX is actually an interspinous destraction device for stenosis, you would code as follows, 22633 (this code replaces 22612 and 22630 01/01/2012), 0171T 51, 20936, 20930 and 38220 51. If the ASPEN LANX is more like a spacer or a cage to hold the graft it would be: 22633, 63047 59, 22851, 20936, 20930 and 38220 51. It is my understanding that usually they use an interspinous destraction device to avoid doing a fusion so I suspect that scenario 2 is more correct but I would double check with your physician.
