Summary & Overview
CPT 49422: Removal of Tunneled Intraperitoneal Catheter
CPT code 49422 denotes the surgical removal of an existing tunneled intraperitoneal catheter used to drain recurrent abdominal fluid collections, such as ascites. Nationally, this code matters because it captures a discrete, procedure-based service tied to chronic fluid management, surgical device management, and post-procedural care pathways. Proper coding affects hospital and ambulatory surgical center claims, device tracking, and case-mix reporting.
Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical intent of the code, typical sites of service, common billing considerations, and the types of benchmarks and policy topics that tend to affect payment and utilization for this service. The publication summarizes typical modifiers and claim-line considerations (where available), highlights payer coverage patterns in broad terms, and outlines policy updates or coding guidance relevant to tunneled peritoneal catheter explantation.
This report is written for a national audience and focuses on clinical context, coding definition, and the policy implications that influence reimbursement and utilization monitoring for CPT code 49422. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 49422 describes the removal of an existing tunneled intraperitoneal catheter used to drain recurrent accumulation of fluid in the abdomen. This procedure involves explantation of a long-term, tunneled peritoneal access device that had been placed to manage recurrent ascites or other chronic intra-abdominal fluid collections.
-
Service type: Surgical removal of a tunneled intraperitoneal (peritoneal) catheter
-
Typical site of service: Hospital operating room or ambulatory surgical center; may also occur in an outpatient procedure suite depending on clinical complexity and institutional practice
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with recurrent malignant or refractory ascites managed with a tunneled intraperitoneal catheter (commonly a peritoneal drainage catheter) placed previously for outpatient intermittent drainage. The patient presents for elective removal because the catheter is no longer needed, has malfunctioned, or there is an infection or complication requiring removal. The workflow begins with pre-procedure evaluation (history, review of indications, medication reconciliation including anticoagulation, and informed consent), imaging review if catheter position or complication is suspected, and coordination of inpatient or ambulatory operating room/stable procedure room scheduling. The procedure is performed by a general surgeon, interventional radiologist, or surgical oncologist under local anesthesia with sedation or monitored anesthesia care; the catheter is dissected free, secured, and removed with attention to hemostasis and closure of the tunneled tract. Post-procedure steps include vital sign monitoring, wound care instructions, infection surveillance, documentation of device removal in the chart and device tracking logs, and coding/billing using 49422 with any applicable modifiers for payer adjudication.
