What 91112 covers
The patient swallows a wireless capsule that records physiologic data as it moves through the gastrointestinal tract. The study can assess gastric emptying and transit through the small bowel and colon, helping evaluate suspected motility problems such as gastroparesis or slow transit. Gastroenterologists and GI motility specialists commonly interpret the recorded data in outpatient settings.
Choose 91112 when the clinical question concerns gastrointestinal transit and pressure, rather than visual inspection of the lining of the digestive tract. Documentation should identify the symptoms or suspected motility disorder, the capsule study performed, the recorded data, and the interpretation. CMS recognizes a professional component for interpretation (modifier 26) and a technical component for equipment and staff (modifier TC); report without a modifier when billing the global service.

- 91111 describes visual capsule imaging focused on the esophagus. 91112 measures motility-related data as the capsule travels through the gastrointestinal tract.
- 91113Colon capsule imagingColon segment
- 91113 is colon capsule imaging, while 91112 measures transit and pressure rather than producing a visual colon examination.

91112 billing questions
How is 91112 different from capsule endoscopy?
91112 measures gastrointestinal transit and pressure. Capsule endoscopy codes describe visual imaging of the digestive tract.
When should modifier 26 or TC be reported?
Use modifier 26 for the professional interpretation and modifier TC for the technical service, including equipment and staff. A claim without either modifier represents the global service.
What documentation supports 91112?
Document the clinical concern, such as suspected delayed gastric emptying or slow transit, along with the capsule study, recorded data, and interpretation.
Is this code for a colonic motility study?
91112 covers wireless capsule measurement of gastrointestinal transit and pressure. 91117 describes a separate colon motility study, so select based on the test actually performed.
