Summary & Overview
CPT 49460: Fluoroscopic Removal of Feeding or Drainage Tube Obstruction
CPT code 49460 documents the fluoroscopically guided removal of a blockage from an existing feeding or drainage tube in the stomach or intestines, often including contrast injection to visualize the tube lumen. Nationally, this service is relevant for acute and chronic enteric access maintenance, preventing interruptions in enteral nutrition or drainage and reducing the need for tube replacement or more invasive interventions. The code is commonly billed when interventional radiology or gastroenterology teams restore tube patency using image guidance.
Key payers covered in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find clinical context for the procedure, typical sites of service, and billing considerations tied to image-guided enteric tube maintenance. The publication summarizes benchmark topics such as typical utilization settings, coding descriptors, and payer coverage patterns where available. It also highlights policy and documentation elements that commonly affect claim adjudication for fluoroscopically guided tube declotting.
This resource is written for a national audience and is intended to orient clinicians, billers, and policy analysts to the clinical purpose and billing context of CPT code 49460. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 49460 describes a procedure to remove an obstruction from an existing feeding or drainage tube placed in the stomach or intestines under fluoroscopic imaging guidance. The provider may inject contrast dye into the tube to improve visualization of the tube lumen and its contents while restoring patency and flow through the device.
-
Service type: Image-guided tube declotting/clearing procedure
-
Typical site of service: Hospital outpatient department, interventional radiology suite, or procedure room where fluoroscopic imaging is available
Clinical & Coding Specifications
Clinical Context
A 68-year-old hospitalized patient with a long-standing percutaneous gastrostomy tube (G-tube) presents with inability to infuse enteral nutrition and progressive abdominal discomfort. Nursing reports difficulty flushing the tube; bedside attempts to irrigate and aspirate fail. The patient has a history of stroke with dysphagia requiring chronic enteral access. The interventional radiology team is consulted. Under fluoroscopic guidance in the IR suite, the provider assesses patency of the existing gastrostomy/jejunal tube by injecting water-soluble contrast through the lumen to localize the obstruction. Using guidewires and catheter manipulation through the tube lumen, the provider dislodges or clears the occlusion and confirms restored flow with repeat contrast injection and aspiration. The procedure is documented with start and stop times, medications administered, level of sedation, type of imaging used, and confirmation of tube function. Typical site of service is the hospital outpatient department or inpatient radiology/interventional suite; this service is commonly billed when tube obstruction cannot be resolved at the bedside and requires fluoroscopic intervention to restore enteral or drainage flow.
