What 51736 covers

The patient voids into a flow-measuring device, which records urinary flow for clinical review. Urologists and urogynecologists commonly use the study when evaluating symptoms such as a weak stream, hesitancy, or suspected impaired bladder emptying. The service can be performed in an office or outpatient setting by the physician or trained staff, with the findings interpreted and reported by the qualified professional.

Report 51736 for the simple flow study, rather than the more involved electronic uroflowmetry represented by 51741. Documentation should identify the clinical reason for testing, the flow study performed, its results, and the interpretation. CMS recognizes professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies the equipment and staff, and an unmodified claim represents the global service. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

51736 billing questions

How does 51736 differ from 51741?

51736 represents a simple urinary flow study. Use 51741 for the more complex, electronically measured uroflowmetry service.

Can 51736 be reported with a cystometrogram?

A flow study and a cystometrogram measure different aspects of urinary function and may be performed during the same evaluation. Document each test performed and its findings.

When should modifier 26 or TC be appended?

Use modifier 26 for the professional interpretation and modifier TC for the technical service, including equipment and staff. Without either modifier, the claim represents the global service.

What documentation supports 51736?

Record the reason for testing, that a simple flow study was performed, the resulting flow data, and the professional interpretation.

How does the multiple-procedure reduction affect 51736?

When 51736 is performed with other procedures in the same session, CMS pays the highest-valued procedure in full and reduces the others to 50%.

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.
