CPT 49407 Image-Guided Drainage Reimbursement | OpenPayer

Summary & Overview

CPT 49407: Image-Guided Transvaginal or Transrectal Catheter Drainage

CPT code 49407 covers image-guided catheter drainage performed via a transvaginal or transrectal approach into the peritoneal or retroperitoneal space. The procedure involves imaging guidance to traverse the vaginal or rectal wall, place a catheter into the target space, and drain fluid collections. This code is relevant nationally for hospitals and interventional radiology practices that manage pelvic and retroperitoneal fluid collections and abscesses where minimally invasive drainage is indicated.

Key payers addressed in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context for the procedure, typical sites of service, and common billing considerations tied to this type of image-guided drainage. The publication also summarizes benchmark payment perspectives, common modifiers reported with this service, and implications for coding compliance and documentation.

The report equips coding professionals, compliance officers, and clinical billing staff with the operational and policy context needed to classify and bill CPT code 49407 correctly, understand payer coverage patterns at a national level, and align documentation practices with the procedural description for accurate reporting.

Billing Code Overview

CPT code 49407 describes a procedure in which a provider uses imaging guidance to place a catheter through the vaginal or rectal wall into a peritoneal or retroperitoneal space to drain fluid once the catheter is correctly positioned. This is a percutaneous, image-directed transvaginal or transrectal catheter drainage procedure.

Service type: Image-guided catheter drainage
Typical site of service: Operative or interventional suite, interventional radiology, or hospital inpatient/outpatient setting where imaging guidance is available

Clinical & Coding Specifications

Clinical Context

A 58-year-old female with a history of recurrent pelvic abscess presents with lower abdominal pain, fever, and leukocytosis. Cross-sectional imaging (CT or ultrasound) demonstrates a loculated fluid collection in the pelvis consistent with a peritoneal abscess adjacent to the vaginal cuff. Interventional radiology is consulted for image-guided drainage. Under conscious sedation in an interventional suite, the provider uses real-time imaging guidance to introduce a drainage catheter transvaginally through the posterior vaginal wall into the abscess cavity, aspirates purulent fluid for culture, and secures an indwelling catheter for continued drainage. The procedure includes pre-procedure consent, sterile draping, local anesthesia, catheter placement using fluoroscopy and/or ultrasound, sample collection, and post-procedure monitoring until recovery. Typical sites of service include the hospital-based interventional radiology suite, ambulatory surgery center, or inpatient radiology department when patients require overnight monitoring.
