What 91125 covers
This study assesses anorectal function using a pressure-sensing catheter and rectal balloon testing. It evaluates anal sphincter pressures and coordination along with rectal sensory responses and the ability to expel a balloon. Gastroenterologists, colorectal specialists, and motility teams commonly perform it in an outpatient motility laboratory for patients with persistent constipation, suspected outlet dysfunction, or fecal incontinence.
Report 91125 when the service includes the combined anorectal manometry, sensory assessment, and balloon expulsion evaluation; document the test elements performed and relevant findings. The global service includes the professional interpretation and the technical work, equipment, and staff. When those portions are billed separately, modifier 26 identifies the interpretation and modifier TC identifies the technical service.

How to choose
91125 billing questions
When should 91125 be selected instead of 91122?
Use 91125 for the combined anorectal pressure, sensory, and balloon expulsion assessment. Use 91122 when the documented service is anorectal manometry without that combined testing.
Are sensory testing and balloon expulsion included?
They are part of the combined service represented by 91125. Document the elements performed and avoid reporting those elements again as separate services from the same test.
How are the professional and technical portions reported?
Report the global service without a component modifier. Use modifier 26 for the professional interpretation or modifier TC for the technical work, equipment, and staff when the portions are billed separately.
What documentation supports 91125?
Record the reason for testing, the anorectal measurements and sensory assessment performed, balloon expulsion results, and the interpreting clinician's findings.
Is 91125 appropriate for constipation alone?
The symptom alone does not establish the service. The record should show that the combined anorectal manometry, sensory assessment, and balloon expulsion evaluation was performed.
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.
