What 43754 covers

A clinician passes a tube into the stomach and aspirates gastric contents to obtain one specimen for diagnostic analysis. The service may be performed in a hospital or another setting where gastric sampling is clinically indicated. It is distinct from placing a gastric tube without diagnostic aspiration and from using intubation and aspiration for treatment.

Report this code when the documented service includes diagnostic gastric aspiration and collection of a single specimen. Documentation should identify the gastric sampling and the specimen collected; when multiple specimens are obtained, the corresponding multiple-specimen code is the relevant comparison. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. Modifier 50 is inappropriate for this service. Assistant-at-surgery services may be paid; co-surgeons and team surgery are not permitted.

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.

43754 billing questions

When should this code be chosen over 43755?

Use this code for diagnostic gastric aspiration with one specimen. Code 43755 is the multiple-specimen counterpart.

Is gastric tube placement by itself enough to report this code?

No. The service includes diagnostic aspiration and collection of a specimen; tube placement alone is represented by 43752.

How does this differ from 43753?

This code describes diagnostic sampling of one gastric specimen. Code 43753 is for therapeutic gastric intubation and aspiration.

Can modifier 50 be used for aspiration from both sides?

No. Bilateral adjustment is inappropriate for this gastric procedure.

What same-day care is included in the global period?

The 0-day global period includes same-day preoperative and postoperative care.

Can an assistant or another surgeon be reported?

CMS permits payment for an assistant at surgery. Co-surgeons and team surgery are not permitted.

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.
