About 63012: Lumbar spondylolisthesis decompression
Reports single-segment lumbar decompression for spondylolisthesis when abnormal facets or pars are removed to free the cauda equina and nerve roots.
63012 represents decompression at one lumbar vertebral segment for spondylolisthesis. The surgeon removes abnormal posterior elements, such as facets and/or the pars interarticularis, to free the cauda equina and nerve roots. This is associated with a Gill-type decompression for a slipped vertebra, rather than a routine lumbar stenosis laminectomy. Orthopedic spine surgeons and neurosurgeons typically perform it in an operating room at a hospital or ambulatory surgery center.
The operative report should identify the lumbar segment, spondylolisthesis, abnormal structures removed, and neural decompression performed. The bone removal and nerve-root decompression are part of this service. CMS classifies it as major surgery with a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment and co-surgeons are permitted; team surgery is not permitted.

63012 billing questions
When should I choose 63012 instead of 63047?
Use 63012 for single-segment lumbar decompression for spondylolisthesis involving removal of abnormal facets and/or pars. Use 63047 for lumbar stenosis decompression when its service description, rather than the spondylolisthesis-specific service, matches the operation.
Can the decompression steps be billed separately?
The abnormal facet or pars removal and neural decompression are integral to 63012. Do not separately report those same steps as another decompression service at that segment.
Should modifier 50 be appended for bilateral work?
No. CMS identifies bilateral adjustment as inappropriate for this code, even when the operative work involves both sides.
What documentation supports 63012?
Document the lumbar vertebral segment, the spondylolisthesis, which abnormal posterior elements were removed, and the cauda equina or nerve-root decompression performed.
How does the 90-day global affect postoperative reporting?
The day-before preoperative visit and 90 days of related postoperative care are included in the major-surgery global period.
