Gastroenterology
About 44407: Colonoscopy with ultrasound-guided needle sampling
Reports colonoscopy with endoscopic ultrasound-guided needle sampling of a target within or beyond the colon wall, including the limited colonic ultrasound examination.
A gastroenterologist or other qualified endoscopist advances a colonoscope to evaluate a target with endoscopic ultrasound and guides a needle through the instrument to sample tissue or fluid. The sampled target may be within the bowel wall or beyond it; the ultrasound examination is limited to the colon. This service is performed in an endoscopy unit, ambulatory surgery center, or hospital setting when needle sampling is needed during the colonoscopy.
Report the service when the record supports both ultrasound guidance and intramural or transmural fine-needle aspiration or biopsy. Document the target, sampling method, and procedure performed; the ultrasound examination is included in this service. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, endoscopy family pricing applies. Modifier 50 is not appropriate for this descriptor. Medicare does not pay an assistant at surgery for this service, and co-surgeons and team surgery are not permitted.
