What 91022 covers
This diagnostic study records pressure patterns in the duodenum to assess how the upper small intestine contracts. A motility catheter is positioned in the duodenum, and the recorded activity is interpreted and reported by a gastroenterologist or another clinician experienced in gastrointestinal motility testing. It is generally performed in a specialized motility laboratory when symptoms or other findings raise concern for disordered small-bowel movement.
Report 91022 for the duodenal motility study, not for testing directed at the esophagus or stomach. Documentation should identify the duodenal study, the recorded findings, and the interpretation and report. The code has a 0-day global period, so same-day preoperative and postoperative care is included. Bill the global service without a component modifier, or use modifier 26 for interpretation or TC for the technical service when billing separately. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

How to choose
- 91010Esophageal manometry
- Use 91010 when the motility study evaluates the esophagus. Code 91022 identifies a study directed at the duodenum.
- 91013Esophageal motility
- 91013 is for esophageal motility testing that includes stimulation or perfusion. It is not the code for a duodenal study.
- 91020Gastric motility
- 91020 evaluates gastric motility; 91022 evaluates duodenal motor activity. The documented study site distinguishes them.
91022 billing questions
How is 91022 different from gastric motility code 91020?
91022 is for a study of duodenal motor activity; 91020 is directed at gastric motility. Select based on the anatomic site studied and documented.
Can the professional and technical portions be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Without either modifier, the claim represents the global service.
Does 91022 have a global period?
It has a 0-day global period. Same-day preoperative and postoperative care is included.
Should modifier 50 be used for a study involving both sides?
No. The code's descriptor or anatomy makes bilateral adjustment and modifier 50 inappropriate.
What should the record support?
Document that the study evaluated duodenal motility, the recorded findings, and the clinician's interpretation and report.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted.
