What 51741 covers
The patient voids into calibrated electronic equipment that records the flow pattern over time and related measurements, such as flow rate and voided volume. Urology practices commonly use the test when evaluating symptoms such as a weak stream, hesitancy, or incomplete emptying, including in patients with suspected bladder outlet obstruction. Staff may operate the equipment, with a qualified practitioner interpreting the results. Unlike pressure testing, this measurement records urine flow during voiding rather than bladder pressure.
Report 51741 for the complex electronic flow study, rather than the simple flow measurement represented by 51736. Documentation should support the indication, the test performed, the recorded results, and the interpretation. The service has professional and technical components: report modifier 26 for the interpretation, modifier TC for equipment and staff, or no component modifier for the global service. 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.

51741 billing questions
When should 51741 be used instead of 51736?
Use 51741 for a calibrated electronic flow study. Use 51736 for simple uroflowmetry; the equipment and method documented should support the code selected.
Can 51741 be reported with a cystometrogram?
Uroflowmetry and cystometrography measure different aspects of urinary function and may be performed in the same urodynamic evaluation. Document each service performed and its results.
Which modifiers identify the professional and technical portions?
Modifier 26 identifies the interpretation, and modifier TC identifies the equipment and staff portion. Without either modifier, the claim represents the global service.
What documentation supports 51741?
Document the clinical reason for testing, that calibrated electronic flow measurement was performed, the recorded flow findings, and the practitioner’s interpretation.
How does the multiple-procedure rule affect 51741?
When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the other procedures are paid at 50% under the standard reduction.
