A patient who has been having chronic reflux is scheduled to have an acid perfusion test performed on the esophagus. This test is also known as the Bernstein test. What is the correct CPT code for this procedure?

91022
91030
91034
91035

Explanation

Answer: B - 91030 is the correct code for the Esophagus acid perfusion (Bernstein) test for esophagitis.
Code 91022 is incorrect because this code is for a duodenal motility study. Codes 91034 and 91035 are incorrect codes because these are used to test for gastroesophageal reflux testing.
