CPT® Code 91030

The CPT® Code 91030 refers to the esophagus acid perfusion test, commonly known as the Bernstein test, which is specifically utilized for diagnosing esophagitis. This diagnostic procedure is essential in distinguishing between chest pain that arises from gastroesophageal reflux disease (GERD) and pain that may be attributed to cardiac conditions. The test involves a series of steps that include the administration of a mild hydrochloric acid solution into the esophagus, allowing healthcare professionals to assess the patient's response to the acid. The procedure begins with the numbing of one nostril using lidocaine, which facilitates the passage of a catheter through the nasal passage and into the esophagus. As the catheter is advanced, the patient is instructed to swallow, aiding in the catheter's progression. The introduction of hydrochloric acid followed by saline solution allows for the evaluation of any discomfort or pain experienced by the patient, providing critical information for accurate diagnosis and treatment planning. This test is particularly valuable in clinical settings where differentiating the source of chest pain is crucial for appropriate management and intervention.
