What 20251 covers
This service involves surgically exposing a cervical or lumbar vertebral body and obtaining tissue for diagnostic evaluation, such as when imaging raises concern for a tumor or infection. A neurosurgeon or orthopedic spine surgeon typically performs it in an operating room. The code is specific to the vertebral body and an open approach; a needle or trocar sample through the skin is a different service.
Select the code when the operative report supports open sampling of a cervical or lumbar vertebral body. Document the spinal region and level, the open approach, and the tissue obtained. Related postoperative visits during the 10-day global period are included. When other procedures are performed in the same session, Medicare pays the highest-valued procedure in full and reduces the others to 50%. Modifier 50 is inappropriate. Medicare may pay for an assistant at surgery, but co-surgeon and team-surgery billing are not permitted.

20251 billing questions
How do I distinguish this from 20250?
Use 20251 for an open biopsy of a cervical or lumbar vertebral body. Code 20250 is for an open thoracic vertebral body biopsy.
Is a needle biopsy reported with this code?
No. A percutaneous trocar or needle approach is distinct from open surgical exposure; consider 20225 when its deep bone biopsy criteria are met.
What documentation supports the open approach?
The operative report should describe surgical exposure of the vertebral body, the cervical or lumbar region and level, and the tissue sampled.
Can modifier 50 be reported?
No. CMS identifies bilateral adjustment as inappropriate for this code.
How are other procedures in the same session paid?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the others at 50%. Related postoperative visits for 10 days are included in this code's global period.
Can an assistant or co-surgeon be billed?
Assistant-at-surgery payment may be made. Co-surgeons and team surgery are not permitted for this code.
