CPT code 51729: Urodynamic study, voiding and urethral pressures2026 Medicare rate & RVUs

Medicare pays $354.05 for 51729 nationally in the office. Local office rates run $312.11–$473.99.

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

What 51729 covers

This complex urodynamic study records bladder pressure during filling, pressure during voiding, and a urethral pressure profile. Urologists and urogynecologists commonly use it when assessing conditions such as urinary incontinence, retention, suspected outlet obstruction, or neurogenic bladder. Testing is generally performed in an office or facility with urodynamic equipment and trained staff; the clinician interprets the pressure data alongside the patient’s symptoms and other findings.

Report 51729 when documentation supports all three parts of the service, rather than a complex cystometrogram with only voiding pressure or only urethral pressure testing. The claim may represent the global service or the professional interpretation with modifier 26 or technical work with modifier TC. Same-day preoperative and postoperative care is included in its 0-day global period. When other procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

How to choose

51728Urodynamic studyWith voiding pressure

51728 includes complex cystometry and voiding pressure studies. Choose 51729 when a urethral pressure profile is also performed.

51727Urodynamic testingWith urethral pressure profile

51727 includes complex cystometry and urethral pressure profiling. Choose 51729 when voiding pressure studies are performed as well.

51726CystometrogramElectronic pressure-volume testing

51726 reports complex cystometry alone. It does not represent the combination of voiding pressure studies and urethral pressure profiling included in 51729.

51725CystometrogramSimple filling-phase study

51725 is a simple cystometrogram. It is not the complex study with both voiding pressure and urethral pressure profile testing represented by 51729.

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.
