What 62329 covers
This service involves placing a needle or catheter into the spinal canal to drain cerebrospinal fluid for treatment, with fluoroscopy or CT used to guide placement. A typical clinical use is therapeutic drainage to reduce elevated CSF pressure, such as in a patient with idiopathic intracranial hypertension. Radiologists, neurologists, and other clinicians who perform image-guided spinal procedures may provide it in a hospital or outpatient setting.
Select this code when the puncture is performed to drain CSF therapeutically and imaging guidance is used; a diagnostic CSF sample alone points to a different service. The record should identify the therapeutic reason, the drainage performed, and the imaging guidance used. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and the others at 50%. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

62329 billing questions
How does this differ from 62328?
62329 is for therapeutic CSF drainage; 62328 is for a diagnostic spinal puncture with imaging guidance. Choose based on the purpose of the puncture, not simply whether CSF is collected.
How does this differ from 62272?
Both describe therapeutic CSF drainage, but 62329 includes fluoroscopic or CT guidance. 62272 is the counterpart when the therapeutic puncture is performed without that imaging guidance.
Can imaging guidance be reported separately?
Fluoroscopic or CT guidance is part of 62329. The record should support the guidance used as part of the puncture service.
What documentation supports therapeutic rather than diagnostic intent?
Document the clinical reason for CSF drainage, the therapeutic drainage performed, and the use of fluoroscopic or CT guidance. A diagnostic workup or CSF sampling by itself does not establish therapeutic intent.
How does Medicare handle multiple procedures in the same session?
The highest-valued procedure is paid in full, and the other procedures are paid at 50%. The service has a 0-day global period, with same-day preoperative and postoperative care included.
Can an assistant or co-surgeon be reported?
