What 62330 covers
62330 represents image-guided percutaneous decompression at one lumbar level, targeting ligamentum flavum that contributes to spinal canal narrowing. Through limited interlaminar access, the operator removes tissue to create more space for neural elements. This is not an epidural medication injection or an implanted-device service. Spine surgeons and appropriately trained interventional pain physicians may perform it in an outpatient procedural or surgical setting for selected patients with lumbar stenosis and related walking-limited symptoms.
Report one unit for the treated lumbar level; the code is priced for bilateral work, so modifier 50 does not increase payment. When another lumbar level is treated in the same session, report add-on code 62331 for that additional level. Documentation should identify each level, the stenosis and ligamentum flavum involvement, the approach, and the work performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. With multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are reduced to 50%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

62330 billing questions
When should 62330 be reported instead of 63047?
62330 describes percutaneous decompression focused on ligamentum flavum at one lumbar level. Code 63047 describes a conventional surgical decompression and is selected when that more extensive operative approach is performed.
How is an additional lumbar level reported?
Report 62330 for the first treated level and add-on code 62331 for each additional treated lumbar level in the same session.
Should modifier 50 be appended for bilateral work?
No. CMS prices 62330 as bilateral, and modifier 50 does not increase payment.
What documentation supports reporting 62330?
Document the treated lumbar level or levels, the stenosis and ligamentum flavum involvement, the percutaneous approach, and the decompression performed.
What postoperative care is included in the global period?
The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care.
