Summary & Overview

CPT 49405: Image-Guided Percutaneous Catheter Drainage, Abdomen and Chest

CPT code 49405 denotes image-guided percutaneous catheter drainage used as first-line therapy to drain fluid collections in the abdomen and chest. This interventional procedure is clinically significant nationally because it provides a minimally invasive option to manage abscesses, effusions, and other fluid collections, often reducing need for open surgery and shortening recovery times. Payers commonly involved in covering this service include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical intent and typical settings for the service, an overview of payer coverage considerations, and benchmarks and coding guidance relevant to billing and documentation. The publication also outlines common billing modifiers and service line implications for hospital inpatient, hospital outpatient, and ambulatory procedure center claims. Where specific input fields were not provided, such as associated taxonomies, ICD-10 diagnoses, and related codes, the document notes that data is not available in the input. This summary equips coding professionals, revenue cycle staff, and clinical leadership with the context needed to classify and submit claims for image-guided percutaneous catheter drainage under CPT code 49405.

Billing Code Overview

CPT code 49405 describes the use of imaging guidance for percutaneous catheter drainage as a first-line therapy for fluid collections in the abdomen and chest. The procedure involves percutaneous insertion of a drainage catheter under image guidance to evacuate or manage fluid collections.

Service type: Image-guided percutaneous catheter drainage
Typical site of service: Hospital inpatient, hospital outpatient, or ambulatory surgical/procedure center settings where imaging guidance and interventional radiology or surgical services are available.

Clinical & Coding Specifications

Clinical Context

A 58-year-old patient presents with fever, left upper quadrant abdominal pain, and leukocytosis. Cross-sectional imaging (CT abdomen/pelvis with contrast) demonstrates a 6 cm peripherally enhancing fluid collection in the spleen consistent with an abscess. Interventional radiology is consulted. After review of imaging and coagulation status, the interventional radiologist performs image-guided percutaneous catheter drainage under CT guidance with local anesthesia and conscious sedation. The procedure includes sterile needle access, tract dilation, placement of a drainage catheter, aspiration of purulent material for culture, and catheter securement with appropriate post-procedure monitoring and drainage output documentation. The typical site of service is an outpatient interventional radiology suite, ambulatory surgery center, or inpatient radiology/procedure suite depending on clinical acuity. The service type is image-guided percutaneous drainage of an intra-abdominal organ (spleen) with catheter placement as first-line therapy for fluid collection/drainage by catheter of abdominal and chest organs, corresponding to 49405.
