What 63020 covers
A spine surgeon uses a posterior approach to relieve pressure on cervical nerve root tissue at one interspace. The operation may involve removing part of the lamina or facet and widening the nerve exit opening; a herniated disc may also be removed when needed. Typical indications include cervical radiculopathy associated with a disc herniation or narrowing around the nerve root. These procedures are commonly performed in a hospital or ambulatory surgery facility.
Report this code for one cervical interspace, documenting the level, side, nerve-root compression, and decompression performed. For another cervical interspace treated during the same session, report the additional-level code 63035 rather than repeating this code. The service has a 90-day global period that includes the day-before preoperative visit and related postoperative care for 90 days. When multiple procedures are performed in the same session, the highest-valued is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery and co-surgeon services may be paid; team surgery is not permitted.

63020 billing questions
When should 63020 be used instead of 63030?
Use 63020 for a single cervical interspace and 63030 for a single lumbar interspace when the comparable nerve-root decompression is performed.
How is a second cervical interspace reported?
Report 63035 for each additional cervical interspace treated in the same session with the primary procedure. Document each level treated.
What documentation supports 63020?
The operative report should identify the cervical interspace and side, the nerve-root compression, and the work performed to decompress it, including any disc removal.
Can modifier 50 be reported?
CMS identifies this as a bilateral procedure; bilateral reporting with modifier 50 is paid at 150%. The operative documentation should support work on both sides.
How does 63020 differ from 63040?
63040 is for cervical nerve-root decompression performed as a re-exploration. Use 63020 for the applicable single-interspace procedure when it is not a re-exploration.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care for 90 days.
