ICD-10-PCS Code For Cerebral Ventricle: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group XW06 includes procedures performed to introduce therapeutic substances into the cerebral ventricle. These ICD-10-PCS codes are used for inpatient documentation when a substance is percutaneously delivered into the cerebral ventricular system as part of treatment or a new technology intervention. Accurate coding within the ICD-10-PCS XW06 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Cerebral Ventricle Introduction Procedure Overview

This procedure group covers introduction procedures into the cerebral ventricle using a percutaneous approach as part of the New Technology section of ICD-10-PCS. These procedures involve delivering a therapeutic substance into the cerebral ventricular system and target the anatomical regions of the brain. Accurate coding ensures inpatient records reflect the specific introduction procedure performed and supports appropriate inpatient reimbursement and case mix assignment.

ICD-10-PCS Code	Description
XW0632B	Introduction of CPI-601 Enzyme Replacement Therapy into Cerebral Ventricle, Percutaneous Approach, New Technology Group 11

Typical Clinical Scenarios

An adult patient with a progressive lysosomal storage disorder causing recurrent accumulation of enzyme-deficient substrate in the central nervous system presents for a planned inpatient administration of a novel enzyme replacement directly into the ventricular system to bypass the blood-brain barrier. The patient is admitted electively for image-guided percutaneous access to the cerebral ventricle and controlled infusion of the therapeutic enzyme to achieve CNS distribution. Typical codes: XW0632B
A pediatric patient with rapidly worsening neurocognitive decline due to confirmed enzyme deficiency is brought to the hospital emergently for urgent delivery of investigational enzyme therapy into the cerebral ventricle after systemic therapy failed to reach therapeutic CNS levels. The procedure uses percutaneous ventricular access in an inpatient setting to provide immediate CNS-directed enzyme replacement aimed at halting acute neurological deterioration. Typical codes: XW0632B
An adult patient who previously received systemic treatment but develops progressive hydrocephalus and persistent central nervous system substrate accumulation undergoes an inpatient percutaneous intracerebroventricular introduction of a next-generation enzyme replacement as part of a new technology therapeutic plan to address refractory CNS disease. The procedure is performed to directly introduce the therapeutic enzyme into the cerebral ventricle to improve ventricular drug distribution when other routes have been ineffective. Typical codes: XW0632B
