About 91013: Provoked esophageal motility study
An add-on to esophageal manometry for provocation with stimulation or perfusion when assessing esophageal motor responses.
This service adds a provocative phase to esophageal manometry, using stimulation or perfusion to assess how the esophagus responds during pressure testing. A gastroenterologist or other qualified clinician typically performs it in a diagnostic endoscopy or motility lab for patients being evaluated for symptoms such as dysphagia or suspected esophageal motility disorders. The stimulation or perfusion is performed as part of the manometric evaluation, rather than as a separate general reflux-monitoring study.
Report 91013 only with the primary esophageal motility study, 91010; it is not a stand-alone service. The record should support the manometry and the additional provocative procedure performed. CMS treats 91013 as an add-on paid within the primary procedure’s global period. The diagnostic service may be billed globally without a modifier, or by component: modifier 26 identifies the professional interpretation and modifier TC identifies the technical service, including equipment and staff.
