Gastroenterology testing

About 91035: Wireless esophageal pH monitoring

Reports ambulatory esophageal acid monitoring with a mucosa-attached wireless electrode to evaluate suspected gastroesophageal reflux and measure acid exposure.

This service uses a wireless pH electrode attached to the esophageal lining to collect acid readings during ambulatory monitoring. A gastroenterologist or other qualified clinician commonly places the electrode during an upper endoscopy; the patient then leaves with the recorder and follows instructions for documenting symptoms and activities. The completed study is analyzed to assess esophageal acid exposure and its relationship to reported symptoms, such as persistent heartburn or regurgitation.

Report 91035 for the wireless, mucosa-attached monitoring method, including electrode placement, recording, analysis, and interpretation. Documentation should identify the clinical reason for testing and support the recorded study and interpretation. The global service includes the professional interpretation and technical recording; modifier 26 identifies the professional component, while TC identifies the technical component. The 0-day global period includes same-day preoperative and postoperative care. Modifier 50 is inappropriate for this service. Assistant-at-surgery payment requires documented medical necessity; co-surgeon and team-surgery billing are not permitted.

91035 billing questions

How does 91035 differ from 91034?

91035 is for pH monitoring with a mucosa-attached wireless electrode. 91034 describes catheter-based esophageal pH monitoring.

Does 91035 include electrode placement and study interpretation?

Yes. The service includes placement of the mucosa-attached electrode, recording, analysis, and interpretation.

Can the professional and technical portions be billed separately?

Yes. Use modifier 26 for the professional interpretation and modifier TC for the technical service; billing without either modifier represents the global service.

Can modifier 50 be reported?

No. Modifier 50 is inappropriate for this service because its descriptor and anatomy do not support bilateral adjustment.

What documentation supports reporting 91035?

Document the reason for reflux testing, the wireless mucosa-attached method, the recorded study, and the interpretation of the results.

Can an assistant surgeon or co-surgeon be reported?

Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeon and team-surgery billing are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
