About 61001: Subdural fluid aspiration by puncture
Report this service for needle access to the cranial subdural space to aspirate a fluid collection or deliver medication into that space.
A neurosurgeon or other qualified physician uses a needle to enter the cranial subdural space, most often to remove fluid from a subdural collection such as an effusion or hygroma. The code also encompasses medication delivery through this subdural puncture. It is distinct from withdrawing fluid from a ventricular cavity, a cistern, or a shunt reservoir; the documented access site determines the appropriate code.
Report the service when the procedure record supports subdural-space access and aspiration or medication delivery. Document the clinical indication, the space entered, the side or sides treated, and what was aspirated or injected. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. The code is priced as bilateral; modifier 50 does not increase payment. 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. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.
