Esophageal pH Probe Monitoring
Esophageal pH monitoring uses an indwelling pH microelectrode positioned just above the esophageal sphincter. The pH electrode and skin reference electrode are connected to a battery‑powered pH meter and transmitter worn as a shoulder harness. The esophageal pH is monitored continuously and a strip chart is used to record the pH determinations. The patient is usually monitored for a 24‑hour period. Esophageal pH monitoring is a medically appropriate adjunct procedure to help establish the presence or absence of gastroesophageal reflux.
Esophageal pH probe monitoring should be coded with procedure codes 91034, 91035, and 78262.
Esophageal pH probe testing (procedure codes 78262, 91034, and 91035) are limited to two services per rolling year, same procedure, any provider.
Claims that are denied for exceeding two services per rolling year may be considered on appeal with documentation of one of the following:
