Motility and Gi Function Studies Billing and Coding Guidelines: A Position Paper of The American Motility Society

Abstract

Tests that measure gastrointestinal function, such as esophageal motility testing, ambulatory twenty-four hour pH, electrogastrography, gastroduodenal, sphincter of Oddi, and anorectal manometry, as well as hydrogen breath testing are now an essential part in the evaluation of patients with functional gastrointestinal disorders. They are widely performed in a variety of clinical settings. In this paper we outline the position of the American Motility Society on billing and coding for these studies, and review the issues for these studies under the current United States Relative Value Scale system. We have also provided an outline for standardization of reports for these procedures, and propose changes and modifications of current medical necessity diagnoses.
