CPT code 51736: Uroflowmetry, simple flow study2026 Medicare rate & RVUs in California

Medicare pays $15.10–$18.40 for 51736 in the office in California, from Chico, CA to San Benito County, CA. Which amount applies depends on the service address.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
