What 43757 covers

A clinician advances an intubation tube into the duodenum and collects multiple aspirate specimens for diagnostic testing. Gastroenterologists and other physicians performing gastrointestinal diagnostic procedures may use this service when duodenal contents need laboratory assessment, including evaluation for suspected small-intestinal bacterial overgrowth. The service involves aspiration of duodenal contents rather than tissue sampling by biopsy.

Select this code when the documented procedure collects multiple diagnostic specimens from the duodenum; a single-specimen collection is represented by 43756. The record should identify the duodenal sampling site, diagnostic purpose, and collection of multiple specimens. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted. Modifier 50 is inappropriate for this service.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
