61026 Ventricular injection Medicare reimbursement rates in Michigan

This service involves delivering medication or another substance into the cerebral ventricles through a ventricular catheter that was implanted previously. A neurosurgeon or another qualified physician managing ventricular access may perform it in a hospital or other procedural setting. Intraventricular treatment is a typical clinical use; the code describes the injection procedure, not a particular medication or diagnosis.

Report the code when documentation identifies the ventricular route, the established catheter, and the substance administered. It is distinct from a new ventricular puncture for drainage and from injection through cisternal access. Medicare assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple 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 for this anatomy. Medicare does not pay an assistant at surgery for this service, and co-surgeon and team-surgery billing are not permitted.
