Gastrointestinal testing

About 91065: Hydrogen or methane breath test

Measures exhaled hydrogen and/or methane after a test substrate to evaluate suspected carbohydrate malabsorption or intestinal bacterial overgrowth.

The test measures hydrogen and/or methane in a patient’s breath after administration of a test substrate. Gastroenterology practices and diagnostic laboratories commonly use it to investigate suspected lactose or fructose malabsorption and intestinal bacterial overgrowth. Serial breath measurements are interpreted in relation to the administered substrate and the clinical question; this is not an esophageal pressure or reflux study.

Report the service when the hydrogen/methane breath test is performed, with documentation identifying the indication, substrate or protocol, test results, and interpretation. The global service includes both the professional interpretation and technical work; modifier 26 identifies interpretation, while modifier TC identifies equipment and staff. The 0-day global period includes same-day preoperative and postoperative care. Modifier 50 is inappropriate for this test. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

91065 billing questions

When is 91065 appropriate instead of an H. pylori breath-test code?

Use 91065 for hydrogen and/or methane testing directed at issues such as carbohydrate malabsorption or bacterial overgrowth. H. pylori breath testing uses codes for that specific diagnostic target, such as 83013.

Can the professional and technical portions be billed separately?

Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service; billing without either modifier represents the global service.

Should modifier 50 be appended for this test?

No. The CMS facts identify bilateral adjustment as inappropriate for this service.

What documentation supports reporting 91065?

Document the clinical indication, the test protocol or substrate, the breath measurements, and the interpretation. These details support that the service was a hydrogen/methane breath test rather than another gastrointestinal diagnostic study.

What does the 0-day global period include?

Same-day preoperative and postoperative care is included in the service.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
