CPT® Code 49407

Image-guided fluid collection drainage by catheter (eg, abscess, hematoma, seroma, lymphocele, cyst); peritoneal or retroperitoneal, transvaginal or transrectal

The CPT® Code 49407 refers to the procedure of image-guided fluid collection drainage by catheter, specifically targeting fluid accumulations such as abscesses, hematomas, seromas, lymphoceles, or cysts. This procedure can be performed in various anatomical locations, including the peritoneal or retroperitoneal cavities, and can be approached transvaginally or transrectally. The physician utilizes imaging techniques such as fluoroscopy, ultrasound, or computed tomography to accurately locate the fluid collection. Once identified, a catheter with a sheath is carefully introduced into the cavity containing the fluid. This process involves passing the catheter through the organ that houses the fluid collection, allowing for effective drainage. The procedure may also include flushing the cavity with sterile saline or an antibiotic solution to ensure the removal of all unwanted fluids, such as pus or blood. Depending on the clinical situation, the catheter may either be removed after the drainage is complete or left in place for ongoing drainage. The transvaginal approach is particularly common for fluid collections associated with urogenital organs, while the transrectal approach is similarly executed but involves access through the rectum. This procedure is essential for managing fluid collections that can cause discomfort or complications if left untreated.
