what documentation is needed for interpretation of a bravo reflux testing system
CPT contains two codes for acid reflux tests: 91032 Esophagus, acid reflux test, with intraluminal pH electrode for detection of gastroesophageal reflux. 91033 prolonged reading. For tests that last less than 24 hours, use 91032. Because the Bravo system is a 48-hour test, assign prolonged reading code 91033, Harris says. For best reimbursement results, report 91033 when the test is completed and the gastroen-terologist analyzes the results.
