Urodynamic testing
About 51792: Urinary reflex response study
Reports a diagnostic study of reflex pathways involved in urinary control, typically when evaluating suspected neurologic impairment affecting bladder or urethral function.
A urinary reflex study evaluates the reflex response involved in urinary control, rather than simply measuring urine flow or bladder filling pressure. The clinician stimulates a relevant reflex pathway and records the physiologic response to assess neuromuscular function. Urologists and other clinicians evaluating urinary dysfunction may order the test when neurologic involvement is suspected; it is commonly performed in an office urodynamics setting by trained staff, with physician interpretation.
Select this service when the documented test is a urinary reflex study, not a cystometrogram, uroflow measurement, or sphincter electromyography study. The record should identify the reflex testing performed, the clinical indication, and the findings supporting the interpretation. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. The service may be billed globally or split into professional interpretation with modifier 26 and technical equipment and staff with modifier TC. When multiple procedures occur in one session, the highest-valued is paid in full and other procedures are subject to the standard multiple procedure reduction. Modifier 50 is inappropriate; assistant-at-surgery payment requires documented medical necessity, and co-surgeons and team surgery are not permitted.
CMS billing rules for 51792
- 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.
- Multiple procedures
- Standard multiple procedure reduction: the highest-valued procedure is paid in full and others at 50% when performed in the same session.
- 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.

51792 compared with similar codes
Office rates for Colorado, from the same CMS release.
51785 reports needle electromyography of anal or urinary sphincter muscle activity; 51792 reports a urinary reflex study, not needle muscle testing.
51726 reports complex cystometry, which measures bladder pressure and filling function. 51792 is selected for reflex response testing.
51741 reports complex uroflowmetry, measuring urine flow during voiding. It is not a study of urinary reflex pathways.

51792 billing questions
How is 51792 different from cystometry?
51792 evaluates a urinary reflex response. Cystometry codes such as 51726 measure bladder pressure during filling and related testing.
Can the professional and technical portions be billed separately?
Yes. Report modifier 26 for the professional interpretation or TC for the technical equipment and staff; without either modifier, the claim represents the global service.
Is modifier 50 appropriate?
No. CMS identifies modifier 50 as inappropriate for this service's descriptor and anatomy.
What same-day care is included in the global period?
The 0-day global period includes same-day preoperative and postoperative care.
How does the multiple procedure rule affect payment?
When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% multiple procedure reduction.
What documentation supports reporting 51792?
Document the clinical reason for reflex testing, the reflex study performed, and the recorded response and interpretation. The record should distinguish the study from pressure testing, urine-flow measurement, and sphincter EMG.
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.
