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.

Coding Specifications

Modifier	Description	When to Use
`26`	Professional component	Use when only the interpreting physician's professional component is billed separately from technical resources.
`50`	Bilateral procedure	Use if the procedural billing system requires indication of bilateral procedures (rare for enteric tube clearance).
`51`	Multiple procedures	Use when `49460` is reported along with other distinct procedures during the same session.
`52`	Reduced services	Use when the procedure is partially reduced or not completed as originally intended.
`53`	Discontinued procedure	Use when the procedure is started but terminated for patient safety before completion.
`62`	Two surgeons	Use when two surgeons share responsibility for the procedure in a co-surgery model.
`66`	Surgical team	Use when a surgical team approach is used and billing requires team modifier.
`73`	Discontinued outpatient procedure prior to anesthesia administration	Use when the outpatient procedure is canceled after patient preparation but before anesthesia and needs documentation.
`78`	Unplanned return to operating/procedure room by the same physician following initial procedure for a related procedure during the postoperative period	Use when re-intervention is required in the immediate postoperative period related to the original procedure.
`80`	Assistant surgeon	Use when an assistant surgeon is documented and an assistant modifier is required by payer.
`81`	Minimum assistant surgeon	Use when a minimum assistant is documented per payer policy.
`82`	Assistant not available	Use when an assistant surgeon is required but not available and documented per payer rules.
`AS`	Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery	Use when an advanced practice clinician acts as the assistant surgeon and payer accepts `AS`.
`TC`	Technical component	Use when billing only for the technical component (equipment, imaging) separate from professional interpretation.
