About 91010: Esophageal pressure motility study
Esophageal manometry records pressure patterns during swallowing to evaluate dysphagia, suspected motility disorders, and esophageal function before selected procedures.
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.
CMS billing rules for 91010
- Global period
- Minor procedure with a 0-day global period: same-day preoperative and postoperative care is included.
- Professional and technical components
- Diagnostic test with a professional component (modifier 26, interpretation) and a technical component (modifier TC, equipment and staff); billing without a modifier is the global service.
- Bilateral procedures
- Bilateral adjustment does not apply; the descriptor or anatomy makes modifier 50 inappropriate.
- Assistant at surgery
- Assistant at surgery is paid only with documentation of medical necessity.
- Co-surgeons
- Co-surgeons not permitted.
- Team surgery
- Team surgery not permitted.

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.
