About 43756: Diagnostic duodenal intubation with aspiration
Reports diagnostic passage of a tube into the duodenum to aspirate one specimen of duodenal contents for laboratory evaluation.
A clinician passes an intubation tube into the duodenum and aspirates duodenal contents for diagnostic testing. The service may be performed when a specimen of duodenal fluid is needed for laboratory evaluation; it is distinct from collecting gastric contents or placing a tube for therapeutic use. The code is for one specimen, making specimen count a key distinction from its duodenal sibling code.
Report the service when documentation supports diagnostic duodenal intubation and aspiration of a single specimen. The record should identify the duodenal site, the diagnostic purpose, and the specimen obtained. 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.

43756 billing questions
When should 43756 be chosen over 43757?
Use 43756 for aspiration of one diagnostic duodenal specimen. The related 43757 code is for multiple specimens.
How does this differ from gastric intubation codes?
43756 involves diagnostic intubation and aspiration in the duodenum. Codes 43754 and 43755 concern gastric specimens, with the specimen count distinguishing those codes.
Can tube placement be billed separately?
The intubation and aspiration are part of this diagnostic service. Do not separately report a tube-placement service for the same intubation.
What documentation supports reporting 43756?
Document that the tube reached the duodenum, that aspiration was performed for diagnostic evaluation, and that one specimen was obtained.
Can modifier 50 be used, or can co-surgeons be reported?
Modifier 50 is inappropriate for this service. CMS does not permit co-surgeons or team surgery; an assistant at surgery may be paid.
What care is included in the global period?
The service has a 0-day global period, which includes same-day preoperative and postoperative care.
