CPT code 91033 is a medical billing code used for a prolonged acid reflux test to evaluate gastroesophageal reflux disease (GERD).
CPT code 91033 is used to describe a prolonged acid reflux test, which is a diagnostic procedure that measures the amount of acid in the esophagus over an extended period. This test helps healthcare providers assess the severity and frequency of acid reflux, aiding in the diagnosis of conditions such as gastroesophageal reflux disease (GERD). By monitoring acid levels, providers can better understand a patient's symptoms and tailor appropriate treatment plans.
For CPT code 91033, which pertains to a prolonged acid reflux test, the following modifiers may be applicable:
