What 43755 covers

The service involves passing a tube into the stomach and aspirating multiple specimens for diagnostic evaluation. A physician, often in a hospital or other facility setting, may perform it when gastric contents are needed for testing, including acid analysis. The code describes obtaining multiple specimens from the stomach, rather than a single specimen or aspiration performed for treatment such as decompression.

Select this code when the procedure documentation supports collection of multiple gastric specimens; a single specimen is described by 43754. Record the diagnostic purpose, gastric site, and number of specimens collected. The service includes the intubation and aspiration; laboratory analysis is a separate service when performed. Medicare assigns a 0-day global period, so same-day preoperative and postoperative care is included. Modifier 50 is inappropriate for this single-organ service. Medicare may pay an assistant at surgery, but does not permit co-surgeon or team-surgery billing for this code.

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.

43755 billing questions

When should 43755 be chosen instead of 43754?

Use 43755 when multiple diagnostic gastric specimens are collected. Use 43754 when the documented service obtains a single specimen.

Does this code include placement of the tube?

Yes. The service includes gastric intubation and aspiration to obtain the specimens; do not treat those steps as separate services within the same procedure.

Does 43755 include laboratory analysis of the specimens?

No. It describes obtaining the gastric specimens, not performing their laboratory analysis.

What documentation supports reporting multiple specimens?

The procedure note should identify the diagnostic purpose, confirm gastric intubation and aspiration, and document that multiple specimens were obtained.

Can modifier 50 be reported?

No. Modifier 50 is inappropriate for this single-organ gastric service.

How is same-day care handled?

The code has a 0-day global period, so same-day preoperative and postoperative care is included. Medicare may pay an assistant at surgery, but co-surgeon and team-surgery billing 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.
