What 91010 covers
Esophageal manometry uses a pressure-sensing catheter passed through the nose into the esophagus to record pressure changes during swallowing. The study evaluates coordinated esophageal contractions and lower esophageal sphincter function, often for dysphagia, suspected achalasia, or other motility disorders. Gastroenterology practices typically perform it in an outpatient motility lab or endoscopy setting, with a clinician interpreting the recorded study and producing a report.
Report the study when standard pressure measurements are performed; document the indication, procedure details, findings, and interpretation. The global service includes both the technical work and interpretation; modifier 26 identifies the professional interpretation, while modifier TC identifies equipment and staff. Same-day preoperative and postoperative care is included in the 0-day global period. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment requires documented medical necessity; co-surgeon and team-surgery billing are not permitted.

How to choose
- 91013Esophageal motility
- 91010 represents standard pressure motility testing. 91013 is added when stimulation or perfusion is performed with the motility study.
- 91037Esophageal impedance
- 91010 records esophageal pressure patterns during swallowing; 91037 evaluates esophageal function using impedance to assess bolus movement or reflux.
- 91034Reflux monitoring
- 91010 evaluates esophageal motility with pressure measurements. 91034 monitors esophageal acid exposure to investigate reflux.
91010 billing questions
When should 91010 be reported instead of 91013?
Report 91010 for a standard esophageal pressure motility study. Use 91013 as an add-on when the study includes stimulation or perfusion.
Can the interpretation and technical service be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service, including equipment and staff. Without either modifier, the claim represents the global service.
What documentation supports 91010?
Document the clinical reason for testing, the study performed, the pressure findings, and the interpreting clinician's report. The record should support that standard esophageal motility measurements were obtained.
Is modifier 50 appropriate for this code?
No. The descriptor and anatomy do not support bilateral reporting, so modifier 50 is inappropriate.
How are same-day services around the test treated?
The code has a 0-day global period, which includes same-day preoperative and postoperative care.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
