CPT® Code 0885T

Colonoscopy, flexible, with initial transendoscopic mechanical dilation (eg, nondrug-coated balloon) followed by therapeutic drug delivery by drug-coated balloon catheter for colonic stricture, including fluoroscopic guidance, when performed

The procedure described by CPT® Code 0885T involves a flexible colonoscopy that incorporates an initial transendoscopic mechanical dilation, specifically utilizing a nondrug-coated balloon, followed by the therapeutic delivery of medication through a drug-coated balloon catheter aimed at treating colonic strictures. Colonic strictures are often symptomatic benign bowel obstructions that can arise from various underlying conditions, including surgical complications, radiation therapy, or inflammatory diseases affecting the intestine. The use of a drug-coated balloon, which may be coated with a medication such as paclitaxel, is designed to provide immediate therapeutic effects post-dilation. This procedure is performed under fluoroscopic guidance, ensuring precise placement and effective treatment of the stricture. The flexible colonoscope is introduced through the rectum and navigated through the colon to locate the stenosed area. Once identified, a balloon catheter is advanced over a guidewire to the stricture site, where it is inflated to mechanically dilate the narrowed segment. Following this initial dilation, the drug-coated balloon is introduced through the endoscope's operating channel, inflated, and held in place to deliver the medication directly to the stricture. This dual approach not only alleviates symptoms but also aims to minimize the risk of stricture recurrence by inhibiting the proliferation of fibrotic tissue.
