Summary & Overview
CPT 62225: Ventricular Catheter Replacement or Flush for CSF Drainage
Headline: CPT code 62225 covers replacement or flushing of a blocked ventricular catheter to restore cerebrospinal fluid (CSF) drainage. Lead: CPT code 62225 identifies a neurosurgical procedure to replace or clear a previously placed ventricular catheter when obstruction prevents CSF from draining; the procedure can be performed with an endoscope and typically occurs in an operating room or ambulatory surgery center.
CPT code 62225 matters nationally because ventricular catheter malfunction can lead to elevated intracranial pressure, infection risk, and neurologic worsening, making timely revision or flushing clinically important. Payers commonly involved in coverage decisions and reimbursement for this service include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
This publication provides a concise clinical and billing overview of CPT code 62225, including the clinical context for use, typical sites of service, and common modifiers used with the code. Readers will find benchmarks on utilization and reimbursement patterns where available, discussion of payer coverage considerations, and operational notes relevant to facility and professional billing. Data not available in the input will be identified as such in the detailed sections.
Billing Code Overview
CPT code 62225 describes the replacement or flushing of a previously placed ventricular catheter for drainage of cerebrospinal fluid (CSF). This procedure is performed when a ventricular catheter is blocked or malfunctioning and requires restoration of CSF drainage; an endoscopic approach may be used.
-
Service type: Surgical/neurosurgical device maintenance and revision
-
Typical site of service: Operating room or procedure suite in an acute care hospital or ambulatory surgery center
Clinical & Coding Specifications
Clinical Context
A 56-year-old male with a history of subarachnoid hemorrhage status post external ventricular drain (EVD) placement presents with declining CSF outflow and rising intracranial pressure measurements on monitoring. Imaging suggests a nonfunctioning ventricular catheter due to intraluminal clot or positional blockage. The neurosurgeon schedules the patient for bedside or operating room revision: removal of obstruction by flushing or replacement of the ventricular catheter. The procedure may be performed under general anesthesia or conscious sedation depending on clinical status and may use a neuroendoscope to visualize the ventricular system. Peri-procedural workflow includes preoperative neurologic assessment, review of intracranial pressure trends and imaging, informed consent, sterile prep and drape, catheter flushing or replacement, CSF sampling as indicated, hemostasis, dressing application, and post-procedure monitoring for neurologic changes and CSF leak.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
00 | No modifier — default | Used when no specific modifier applies to the service. |
22 | Increased procedural services | When the procedure required substantially greater work than typical due to extensive adhesiolysis, dense blockage, or complex anatomy. |
