Gastroenterology Coding Alert
Turn to This Code for Reflux Test with Nasal Catheter
Question: My gastroenterologist conducted an esophageal acid reflux test using a disposable nasal catheter. Which code do I report? Does duration of placement matter? South Dakota Subscriber Answer: When a gastroenterologist provides an esophageal acid reflux test using either a disposable or a reusable nasal catheter, you would report 91034 (Esophagus, gastroesophageal reflux test; with nasal catheter pH electrode(s) placement, recording, analysis and interpretation). In terms of duration, make 91034 your go-to code regardless of how long the nasal catheter remains in place. Typically, however, the physician will leave the catheter in place for about a day. In the past, you had to distinguish between standard and “extended” pH monitoring. Currently, only one code (91034) describes a catheter-based pH service. On the other hand, if your gastroenterologist conducts pH testing using a Bravo capsule, you will turn to 91035 (Esophagus, gastroesophageal reflux test; with mucosal attached telemetry pH electrode placement, recording, analysis and interpretation) instead of 91034.
