What 63308 covers
Code 63308 captures removal of an additional vertebral segment during transpedicular resection to excise an intraspinal lesion. Spine surgeons, including neurosurgeons and orthopedic spine surgeons, report it when the resection involves more segments than the primary procedure represents. The primary code distinguishes extradural from intradural disease and identifies the spinal region; this add-on accounts for each additional segment removed.
Report 63308 only with a qualifying primary procedure from 63300–63307, not for the first segment alone. The operative report should identify the lesion, its extradural or intradural relationship, the spinal region, and each additional vertebral segment resected. CMS treats 63308 as an add-on: it is billed only with a primary procedure and paid within that procedure’s global period. It is not a stand-alone service for a separate encounter.

How to choose
- 63300Vertebral resectionCervical, extradural, single segment
- 63300 is the primary code for resection of an extradural cervical lesion. Code 63308 accounts for additional vertebral segments and must accompany a qualifying primary code.
- 63301Vertebral resectionThoracic, extradural lesion
- 63301 identifies a primary extradural thoracic resection. It does not represent an additional segment in the way 63308 does.
- 63304Spinal lesion surgeryCervical, intradural
- 63304 is the primary code for an intradural cervical lesion. Choose the primary code based on lesion relationship and region; use 63308 for additional resected segments.
63308 billing questions
When is 63308 reported instead of a primary code?
Use 63300–63307 for the primary resection, based on the lesion’s extradural or intradural location and spinal region. Report 63308 for each additional vertebral segment resected beyond the segment represented by the primary procedure.
Can 63308 be billed by itself?
No. It is an add-on code reported with a qualifying primary resection code from 63300–63307.
What documentation supports an additional segment?
The operative report should identify each additional vertebral segment actually resected as part of the intraspinal lesion procedure. It should also support the primary code’s lesion relationship and spinal region.
How does CMS treat payment and the global period?
CMS requires 63308 to be billed with a primary procedure and pays it within that procedure’s global period.
Can a modifier make 63308 payable without its primary code?
No. A modifier does not replace the required primary procedure; 63308 remains an add-on to a qualifying resection code.
