What 63064 covers
This service involves reaching a thoracic spinal lesion through a costovertebral exposure and decompressing the spinal cord or nerve root at one segment. The surgeon may remove bone or address a herniated thoracic disk as part of the decompression. Spine surgeons, including orthopedic surgeons and neurosurgeons, typically perform it in a hospital or other facility operating room.
Select the code when the documented approach is costovertebral and the work treats one thoracic segment; identify the level, pathology, approach, and decompression performed. For additional segments, CPT add-on code 63066 may be reported with this primary procedure when its requirements are met. The 90-day global period includes the day-before preoperative visit and related postoperative care. When other procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be made; co-surgeons require supporting documentation, and team surgery is not permitted.

63064 billing questions
How does this differ from 63055?
Both describe thoracic spinal cord decompression, but 63064 uses a costovertebral approach. Code 63055 is for a transpedicular approach.
Can 63066 be reported with 63064?
CPT add-on code 63066 may be reported for an additional thoracic segment treated through the costovertebral approach. Documentation should establish the additional level and work.
Is disk removal separately reported?
Disk removal performed as part of the decompression is included in this service. Do not separately report another procedure for the same disk work.
Should modifier 50 be used for bilateral work?
No. The descriptor and anatomy make modifier 50 inappropriate for this code.
What documentation supports code selection?
Document the thoracic level, the costovertebral approach, the condition treated, and the decompression performed. If additional segments are treated, identify each one.
