CPT® Code 91010

Esophageal motility (manometric study of the esophagus and/or gastroesophageal junction) study with interpretation and report;

The CPT® Code 91010 refers to an esophageal motility study, which is a diagnostic procedure designed to assess the function of the esophagus and the gastroesophageal junction. This study is particularly useful in identifying the underlying causes of swallowing difficulties and non-cardiac chest pain. During the esophageal motility study, the muscle contractions of the esophagus are evaluated, providing critical insights into esophageal function. A common condition diagnosed through this procedure is esophageal achalasia, a disorder characterized by the inability of the lower esophageal sphincter to relax properly, coupled with uncoordinated contractions of the thoracic esophagus. This dysfunction can lead to a functional obstruction of the esophagus, making it difficult for food and liquids to pass into the stomach. To perform the study, a catheter equipped with a manometer is introduced through one of the nostrils, which is first numbed with lidocaine to minimize discomfort. The catheter is then carefully advanced through the pharynx and into the esophagus, with the patient asked to swallow to facilitate the catheter's movement. The procedure involves measuring the contractility of the lower esophageal sphincter, followed by the assessment of muscle contractility in the mid-esophagus after the patient sips water. The results are displayed on a manometry monitor as a two-dimensional (2D) graph, which the physician later reviews to provide a comprehensive written evaluation of the esophageal motility. This detailed analysis is essential for diagnosing various esophageal disorders and guiding appropriate treatment options.
