While treating gastroesophageal reflux disease (GERD), your physician may conduct such diagnostic tests as esophageal motility studies to learn the condition prior to a surgical intervention. Read on to know how you can code these tests for optimal results.
Read For Both Manometry and pH Monitoring
The gastroenterologist will most likely choose esophageal manometry if he is trying to assess the patient’s esophagus for neuromuscular disorders. “Esophageal manometry studies are used to evaluate how well the esophagus functions,” says Bridgette Martin, LPN, CPC, CGIC, Coding Specialist-Gastroenterology Associates, Evansville, Indiana. “They may also be ordered to evaluate a patient prior to recommending anti-reflux surgery.” The patient’s documentation will probably show mention of a “manometry nasal catheter” and pressure readings. You report this procedure with 91010 (Esophageal motility [manometric study of the esophagus and/or gastroesophageal junction] study with interpretation and report).

Your gastroenterologist might chose the use of a medication stimulant during the motility studies. If that’s the case, you should report the procedure with 91013 (Esophageal motility [manometric study of the esophagus and/or gastroesophageal junction] study with interpretation and report; with stimulation or perfusion [e.g., stimulant, acid or alkali perfusion] [List separately in addition to code for primary procedure]).
Another test that your gastroenterologist will usually perform while assessing a patient with GERD is pH monitoring using a pH probe placed through a nasal catheter. “pH studies...
