Gastrointestinal testing

About 91132: Diagnostic electrogastrography without challenge

Electrogastrography records gastric electrical activity without a provocative test, helping evaluate patients with symptoms such as persistent nausea or vomiting.

Electrogastrography uses sensors placed on the abdominal skin to record the stomach’s electrical activity. A gastroenterologist or other qualified clinician may order it when evaluating upper gastrointestinal symptoms, including persistent nausea or vomiting, and possible abnormalities in gastric electrical rhythms. The study is noninvasive and may be performed in an outpatient setting. This code distinguishes a recording without a test or challenge from the related service that includes one.

Report 91132 for the electrogastrography service without a provocative test; documentation should identify the recording performed and support that no test component was included. CMS recognizes separately priced professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies the equipment and staff, and an unmodified claim represents the global service. The record should support the portion billed, including the interpreting clinician’s report for the professional component or the technical resources furnished for the technical component.

CMS billing rules for 91132

Professional and technical components
Diagnostic test with a professional component (modifier 26, interpretation) and a technical component (modifier TC, equipment and staff); billing without a modifier is the global service.

91132 billing questions

How does 91132 differ from 91133?

91132 is for electrogastrography without a test or challenge. Use 91133 when the study includes a test component, such as a meal challenge.

Which modifier identifies the interpretation?

Append modifier 26 when billing only the professional interpretation. The interpreting clinician’s report should document the results.

When is modifier TC appropriate?

Use modifier TC when billing only the technical portion, including the equipment and staff. An unmodified claim represents the global service.

Can the professional and technical portions be billed separately?

Yes. CMS separately prices the 26 and TC components; the global service is billed without either modifier.

What documentation distinguishes this code from a challenged study?

Document the electrogastrography recording and whether a test or challenge was included. A study with a test component belongs to 91133 rather than 91132.

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.
