What 51728 covers
This urodynamic test records bladder pressure as the bladder fills and during voiding, helping assess how the bladder stores and empties urine. Urologists and urogynecologists commonly order it for patients with urinary retention, incontinence, suspected outlet obstruction, or neurogenic bladder. Testing is generally performed in an office or facility with catheter-based pressure measurement and recording equipment.
Report 51728 when the completed study includes complex cystometry and voiding pressure assessment; a filling-only complex study or one that also includes a urethral pressure profile may call for a different code. The record should support the study performed and its interpretation. The global service includes the professional interpretation and technical work; modifier 26 identifies interpretation, and modifier TC identifies equipment and staff. This has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued is paid in full and others are subject to the standard 50% reduction. Bilateral adjustment is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

51728 billing questions
When should 51728 be selected instead of 51726?
Use 51728 when the complex cystometric study includes assessment of voiding pressure. A complex filling study without that voiding-pressure component is distinguished by 51726.
How does 51728 differ from 51729?
51729 includes a urethral pressure profile in addition to complex cystometry and voiding pressure assessment. Use 51728 when the documented study includes voiding pressure but not that additional profile.
Can the professional and technical portions be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical portion, including equipment and staff. Without either modifier, the code represents the global service.
Can 51797 be reported with 51728?
51797 is an add-on for a separately performed intra-abdominal voiding pressure study and may be reported with 51728 when that additional study is performed and documented.
What documentation supports reporting 51728?
Document the complex cystometric testing, the voiding pressure assessment performed, and the interpretation or findings. The record should distinguish the service from filling-only cystometry and from a study that includes a urethral pressure profile.
How does the multiple-procedure reduction affect 51728?
When it is one of multiple procedures performed in the same session, the highest-valued procedure is paid in full and the other procedure or procedures are subject to the standard 50% reduction.
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.
